Definitions
- the present invention relates to surfaces of objects, in particular liquid-absorbing containers with a surface and a method for producing the surface that is extremely hydrophobic.
- the invention describes in particular the excellent use of such an extremely hydrophobic surface in the pouring area of a liquid-holding container and / or in the inner wall region of such a liquid-holding container, liquids also being understood to mean those liquids which already have poor-flowing behavior (such as honey), pasty or thixotropic (e.g. ketchup, mayonnaise).
- the highly hydrophobic surface can be formed on various materials such as metals, glasses, plastics or ceramics and is also suitable for bulk goods and for any geometries.
- the wetting behavior of a surface is determined by two factors:
- the microscopic, morphological structure of the surface which depending on its nature can support or weaken the water-repellent behavior of liquids in close dependence on the chemically induced surface.
- the effect observed in some plants that individual parts of plants are completely non-wettable with water which has an advantageous self-cleaning effect for these plants.
- This phenomenon is based on the presence of small elevations, which can either be wax crystals or wax-covered, papillary cell protrusions.
- drops e.g. raindrops
- the lotus effect is particularly described in "Barthlott, W. & C. NEINHUIS (1 997), Purity of the sacred lotus, or escape from contamination in biological surfaces, Planta 202, pages 1 to 8; BARTHLOTT, W. & Co.
- NEINHUIS (1 998), lotus flowers and car paints, ultrastructure of plant interfaces and biomimetic, dirt-free materials, BIONA-REPORT 1 2, Proc. Int. Congress GTBB, pages 281 to 293, Akad. Wiss. Lit. Mainz (Gustav Fischer Verlag), BARTHLOTT, W. & C. NEINHUIS (1 998), Lotus effect and car paint, The self-cleaning of microstructured surfaces, BiuZ 28, pages 314 to 321.
- the surface structuring consisting of elevations and depressions of a material that is inherently hydrophobic, is taken into account as well as the subsequent hydrophobization of a surface-structured, non-water-repellent material and the application of hydrophobic surface structures to a non-water-repellent material.
- the size of the effective surface structures is explicitly set in a range from 5 ⁇ m to 200 ⁇ m, that is, the distance between the elevations is in the range from 5 ⁇ m to 200 ⁇ m.
- EP 0 909 747 describes the production of self-cleaning water-repellent bricks by dispersing inert powder articles which are wetted with a siloxane solution, which is then cured.
- the water-repellent effect is achieved through the interaction of surface structure and hydrophobicity.
- the size of the surface structure is set to 5 ⁇ m to 100 ⁇ m.
- US-A-3,354,022 describes a method for hydrophobicizing surfaces by spraying on a paraffin solution or dispersion. The volatilization of the dispersant or solvent results in wax bumps from 50 ⁇ m to 80 ⁇ m in diameter at a mutual distance of 20 ⁇ m to 1 60 ⁇ m.
- CH-PS 26 82 58 describes water-repellent surfaces which are produced by applying previously hydrophobized, ceramic powder together with curable resins to a surface.
- Hydrophobic surfaces can also be produced using a special plasma polymerization technique (DE 1 95 43 1 33 C2).
- the large-scale implementation, especially with regard to the task, is not possible.
- the structuring of the surface is not used.
- the object of the invention is first of all to develop a simplified method for producing a self-cleaning, extremely hydrophobic surface.
- the aim should also be achieved, as far as possible, of producing a reproducible surface which can be formed from different materials and which has a contact angle with water of not less than 120 °, preferably not less than 140 °.
- Another object is to be achieved, namely to greatly improve the pouring behavior of containers which can hold liquids.
- the object of providing attractive, transparent containers which allow the material stored in them not to adhere to the inner wall of the container is also to be achieved.
- the invention is based on the knowledge that self-cleaning surfaces, even those as are known from the prior art, can be used in an outstanding manner to improve the pouring behavior of containers if a self-cleaning surface is formed in the pouring area, in which case the adhesive force acting on the liquid is drastically reduced.
- a self-cleaning surface whose surface structures are less than 5 ⁇ m is particularly suitable. This is all the more surprising, since EP 0 772 514 expressly points out that the surface effect which is less than 5 ⁇ m cannot be determined by the self-cleaning surface effect. Surface structures in the range from 10 ⁇ m to 100 ⁇ m are therefore also proposed as optimal.
- EP 0 909 747 or US-A-3, 354,022 also describe Surface structures whose size is always over 5 ⁇ m.
- the pouring behavior of such a container is improved in such a way that liquid drops do not run off the outside of the container (due to the minimization of the adhesive force occurring there).
- a technical solution is provided which eliminates a problem that is thousands of years old, namely preventing the undesired running of drops on the outside of a container when / after pouring liquids out of the container.
- This improved pouring effect can be achieved regardless of the base material used for the container, even if the surface structure has a size in the range from 0.1 ⁇ m to 200 ⁇ m.
- a suitable morphological surface structure is created. This can be done using fine blasting, for example, but also using other techniques such as embossing or etching.
- the morphological surface structure is preferably achieved by (fine) blasting the surface with suitable blasting material (e.g. blasting material made of corundum with a grain size of 0.15 mm to 0.35 mm; blasting material with sharp-edged grains is particularly suitable).
- suitable blasting material e.g. blasting material made of corundum with a grain size of 0.15 mm to 0.35 mm; blasting material with sharp-edged grains is particularly suitable.
- the choice of the blasting material and the parameters used depend on the given substrate material, which can be a polymer, metallic or ceramic structure.
- the decisive factor is that the blasting material through the Formation of a fine-rough surface structure of the size in the range of less than 200 ⁇ m causes what is preferably accomplished by pointed grains. It is also important that the processed material is not broken, which is particularly important for plastic.
- the blasting material itself should not remain in the processed surfaces in order to ensure good adhesion of the subsequent coating, which is why the blasting process is usefully followed by a cleaning that maintains the surface structure.
- the blasting process must be carried out in such a way that too much material is not removed by over-treatment, so that PE is removed from disposable packaging made of PE-coated cardboard. It should only be structured.
- the suitable morphological surface structure is formed or embossed, this can be done, for example, with an embossing stamp, which is also possible at room temperatures if the substrate, for example the surface of a package, e.g. is a commercially available milk packaging.
- the second step in the production of the hydrophobic surface consists in applying a contour-simulating coating, which would be applied to smooth substrates and would have a wetting angle between 90 ° and 120 °.
- This coating can also perform other functions such as Have corrosion protection or a sealing effect.
- the contour-simulating coating should be characterized in particular by a low surface energy and can be applied, for example, using the plasma polymerization process. Here, either low pressure or atmospheric processes can be used. As an alternative or in addition to plasma polymerization, methods such as the sol-gel method, siliconization, teflonization or other methods can also be used.
- the contour-simulating coating is characterized as follows:
- a gas of a suitable chemical composition e.g. HMDSO
- a layer is deposited on a presented substrate, in the present case on the structured surface (after the first step).
- the contour-simulating coating can be applied to all types of material and adheres equally well to all of them. Depending on the process, this can be explained by the fact that the reactive particles generated in the plasma chemically bind to them. The preservation of the surface structures is guaranteed.
- the layer thickness can be in the range from 0.1 nm to 400 nm, preferably in the range from 1 nm to 50 nm, and its thickness can also be applied in a precisely defined manner.
- the contour-simulating coating can be closed on the pre-structured surface, but it can also not be closed at all.
- a closed coating is to be expected in the layer thickness range of approximately 5nm to 50nm. But only partial coatings (e.g. only on the elevations) already show the desired hydrophobic effect according to the invention, this taking place particularly with a "uniform" partial coating.
- the layer thickness of the contour-simulating coating can be essentially constant, but it is also entirely possible for the layer thickness to correspond to the Elevations and depressions are different and the layer thickness on the elevations, at least their exposed parts, is greater on average than the layer thickness on the depressions.
- the advantage of the method according to the invention is the very simple production of extremely hydrophobic surfaces on materials of the most varied of geometries and properties, even with material combinations.
- the sealing force can be set in a defined manner via the layer thickness of the (plasma polymeric) coating between no change compared to the uncoated material (small layer thicknesses approx. 1 nm to 10 nm) and no sealing ability (high layer thickness from 100 nm).
- the sealing force is particularly important where, for example, packaging, such as standard milk packaging from Tetra-Pack ® , has two layers of packaging material (coated paper) lying on top of each other, which are connected to each other and which should also be sealed at the same time.
- packaging such as standard milk packaging from Tetra-Pack ®
- packaging material coated paper
- the tear-open behavior of a package preferably a one-way package
- the tear-open behavior of a package can also be adjusted so that it can be more easily detached from one another at the preferred tear-open points, with adequate liquid sealing in the unopened state given is.
- hydrophobic surface not only can self-cleaning be achieved, but also the pouring behavior of objects in which liquids or flowable foods are stored.
- objects include, for example, bottles, milk churns (ceramics), coffee or teapots (glass), juice or milk disposable packaging (coated paper), ketchup or sauce bottles etc.
- the hydrophobic surface can be attached to the outside of the packaging, for example in the roof area of the packaging. This is preferably pre-punched in the pouring area, so that it can be more easily pressed in or the corresponding part can be torn out. If the described hydrophobic surface delimits the pouring opening, no liquid can be captured and retained on the outer edge during pouring, but all liquid is poured out with it and no undesired drainage drops form on the outside of the packaging.
- the packaging can also be provided that it also has an adhesive cover, which is detachable on one side of the packaging and which can be attached to the packaging with the loosened side after the partial emptying of the packaging, so that the pouring opening is closed almost airtight (or completely airtight), so that even if the packaging is inadvertently inclined, the outflow of liquids is prevented as far as possible.
- an adhesive cover which is detachable on one side of the packaging and which can be attached to the packaging with the loosened side after the partial emptying of the packaging, so that the pouring opening is closed almost airtight (or completely airtight), so that even if the packaging is inadvertently inclined, the outflow of liquids is prevented as far as possible.
- the hydrophobic surface according to the invention can also be a flow surface which covers the outer skin of an aircraft or a vehicle (railroad, car, ship, bicycle, boat, paddle, sports boat, surfboard) or the inner wall of a pipe (pipeline) of any kind.
- the formation of the hydrophobic surface not only improves the flow behavior in general, i.e. the flow resistance is reduced, which entails less energy (or higher speed with the same effort) for the movement of the respective vehicle, but especially in rainy weather, fuel can be saved considerably, because the raindrops hitting the aircraft or vehicle move much faster with the Airstream can be brushed away.
- the external attachment of the described hydrophobic surface according to the invention to the ship's outer walls, in particular to its underwater area also appears sensible in order to reduce the friction between water and the ship.
- the use of the surface according to the invention also makes it possible to avoid icing on aircraft or other objects which experience rapid movement through the air.
- Rain for example falling or hitting a flying aircraft and being carried away by it, tends to evaporate faster, which leads to additional evaporative cooling on the surface of the aircraft, which then supports "immediate” icing of the affected surface (flash ice).
- the formation of a highly hydrophobic surface according to the present invention provides in particular in cooperation with the high Lucasgeschwindig ⁇ ness that the water drops leave immediately the surface again, so that the problem of evaporative cooling and icing does not arise at all. As a result, the aircraft is lighter overall and therefore requires less energy when flying. This also applies to the formation of the surface according to the invention on the rotor blade of a wind turbine.
- the surface according to the invention can be used wherever objects come into contact with liquids or dusts and where it is desired that the adhesion between the liquid or dusts and the article is reduced and / or minimized. This is e.g. with a liquid line, e.g. a pipeline, the case.
- Example 1 The invention is explained below using several exemplary embodiments.

- Example 1 The invention is explained below using several exemplary embodiments.
- Example 1 Example 1 :
- a surface made of aluminum (AIMg3SiO, 5) is blasted evenly with blasting material made of corundum.
- the workpiece is then cleaned in ethanol in an ultrasonic bath and, after drying, transferred to a plasma reactor.
- the aluminum surface is provided with a plasma polymer coating according to the prior art.

- H2 ⁇ wetting angles result:
- the invention also makes it possible not only to provide the pouring area of liquid-absorbing containers with an extremely hydrophobic surface, but also the inner wall of these containers. This makes it possible that even with the intake of viscous or tending to thixotropy Masses (liquids) that do not get stuck on the inside of the wall, for example when the container is partially emptied, but the bulk material remaining in the container, including material that initially adheres to the inner wall, flows down as far as possible, so that if the container is transparent, it looks very aesthetically appealing to the viewer. This also results in improved hygiene because the contact area between the bulk material, e.g. ketchup, mustard, sauce etc.
- FIG. 1 shows a cross section through a surface according to the invention.
- FIG. 2 shows a cross section through a surface according to the invention with a water drop lying thereon;
- 3 shows a cross section through the upper part of a bottle in cross section with the surface according to the invention applied on the inside and outside;
- FIG. 4 shows a plan view of the upper part of a milk packaging with a surface according to the invention partially applied there;
- Fig. 7 is a microscope image (enlarged view of FIG. 6) of a structured surface according to the invention.
- the surface shows a surface 7 according to the invention, which is formed on a substrate 1 consisting, for example, of plastic, glass, ceramic or metal.
- the surface consists of elevations 2 and depressions 3.
- the distance between adjacent elevations is (on average) less than 5 ⁇ m, e.g. the distance between the elevations is measured from the elevation peak to the elevation peak, which are projected onto a common line.
- the height of the elevations is preferably also less than 5 ⁇ m, e.g. the height of the bumps is measured from the top of a bump to the adjacent lowest level of the depression.
- the surface 7 structured in this way is not uniform, which is not excluded, but rather structured irregularly, the distances between adjacent elevations 5 also being regularly different.
- a contour-reproducing layer 4 which consists of a preferably extremely hydrophobic material, is applied to the morphological surface structure of the substrate 1.
- the chemical composition of this coating is selected so that it would produce contact angles of more than 90 ° with water even on a completely flat surface.
- the layer 4 is preferably coated by plasma polymerization, the coating material being deposited on the elevations and depressions.
- the layer thickness is less than 500 nm, preferably in the range from 0.1 nm to 300 nm. Particularly good results were achieved in tests with a layer thickness of more than 7 nm.
- a contact angle or wetting angle is established between the surface 7 and the ball, which is significantly greater than 1 20 °, e.g. 140 ° and more.
- the contact angle is measured by applying a tangent to the water droplet surface and touching the surface 7 and a horizontal 16.
- the water drop tends to bead up easily from the surface.
- the adhesion between water drops and the surface is extremely low and many times less than when the water drops on a flat surface, e.g. Glass surface would lie, at which then a contact angle of significantly less than 90 ° (e.g. 45 °) is regularly established.
- FIG 3 shows the cross section through the upper section of a liquid-absorbing container, for example through a bottle 9.
- This bottle 9 consists of glass with an inner wall 1 2 and an outer wall 1 3 and an outer pouring area 8, usually also called bottle opening.
- the hydrophobic surface 7 is formed both on the inside of the bottle and in the outflow area and also projects somewhat beyond the upper edge of the bottle.
- liquid in the bottle e.g. Poured water
- it easily detaches from the surface 7 so that not one or more drops run down - as usual - when the bottle is swung back into the vertical position on the outer wall 1 3 of the bottle.
- Liquid lying on the inside of the wall 1 2 of the bottle cannot get stuck there due to the low adhesive force and sinks downwards until the liquid remaining in the bottle has reached its maximum fill level.
- liquid-absorbing containers If the liquid is rather viscous, such as a salad dressing or ketchup, it also sinks on the inside due to the surface 7 formed, so that the viewer of the bottle has the impression that the inside of the bottle has been cleaned. This considerably improves the aesthetic impression of such liquid-absorbing containers when they are to be used in the catering sector.
- FIG. 4 shows the upper part of a disposable milk packaging (milk carton) as a liquid-absorbing container.
- This milk packaging is folded to form it, the packaging material being regularly coated paper.
- this has, for example, a roof, the upper edge of which regularly has layers of material butting against one another, which are folded and / or sealed so that they can be glued together.
- a surface 8 with the hydrophobic surface 7 is formed in the roof area.
- a perforation 11 follows within this area 8. Under certain circumstances, this can also only protrude into the surface 8 with its lower part.
- This perforation (it can also be a pre-cut without to break through the material at this point) is used so that the roof of the packaging can easily break through at this point and press the pre-perforated surface inwards or tear it outwards.
- the milk in the packaging can be poured out, and due to the formation of the surface 7 in the pouring area of the milk packaging, no milk runs down there on the outside of the milk packaging even when the pouring angle is very small.
- FIG. 5 shows a microscopically enlarged image of a milk packaging carton in the original state (unexposed). As can be seen, the surface is not evenly structured and largely flat.
- FIG. 6 shows the microscopically enlarged illustration of the outside of the carton in the pouring area in the state after the structured surface according to the invention has been produced.
- the surface structure is not only extremely irregular, but is also characterized by a large number of elevations and depressions distributed over the entire surface.
- FIG. 7 shows a further microscopically enlarged representation of the surface 7 according to FIG. 6. From the scale given below the picture, it can be seen in comparison with the picture representation that an extremely unevenly structured surface is again formed, the distances between adjacent elevations are significantly less than 5 ⁇ m.
- FIGS. 6 and 7 were produced by (fine) blasting. Such structuring of the surface is, however, also possible by means of engraving or embossing stamps or also by etching the surface, as is shown in FIG. 5.
- the surface according to the invention can also be formed on the inside of a freezer or refrigerator or on the inside wall of a freezer or cold store. det be. This prevents ice build-up, which has previously led to long downtimes for freezers, refrigerators, freezers or cold stores.
