Background technology
The high score that laminated film is composited by the film of two layers or multiple layers of different materials by modes such as gluing or hot pressing
Sub- material, laminated film can be made up of the film of multiple layers of different materials, therefore laminated film can be made to have multiple material concurrently
Partial properties, assign the more combining properties of laminated film.At present, laminated film is widely used in packaging field, due to THIN COMPOSITE
Film has pliability strong, and mechanical property is excellent, the low feature of production cost, researcher gradually by laminated film apply sensor,
The field such as ultracapacitor and functional fibre, still, traditional laminated film surface is all smooth, exists and compares surface
The small shortcoming of product, it is impossible to preferably realize sensing, conductive, the function such as absorption.
The content of the invention
To solve problem above, it is an object of the invention to provide a kind of laminated film of nanofiber surface and its preparation side
Method, the laminated film has the characteristics of specific surface area is big.
To achieve the above object, the technical scheme designed by the present invention is：
The laminated film of nanofiber surface, including basement membrane, the outer surface of the basement membrane are pasted with nano fibrous membrane, described
The average diameter of nanofiber is 50~800nm in nano fibrous membrane；The basement membrane is polypropylene, polyethylene, polyester and polyamides
One kind in amine, the nano fibrous membrane is one kind in polypropylene, polyethylene, polyester and polyamide；The thickness of the basement membrane
For 50~100 μm, the thickness of the nano fibrous membrane is 50~100 μm.
Preferably, the nano fibrous membrane is same material with basement membrane.
The preparation method of the laminated film of nanofiber surface, comprises the following steps：
1) outer layer copolymer in mass ratio, is weighed：Acetylbutyrylcellulose is 1:9~4:6, it is used as outer layer after being well mixed
Film raw material, double-deck cast film machine is put into by outer layer film raw material and basement membrane polymer, through double-deck cast film machine extrusion, simple tension and
It is cooled and shaped the laminated film for obtaining being overlapped after process by basement membrane and outer membrane；The outer layer copolymer be polypropylene, polyethylene,
One kind in polyester and polyamide, the basement membrane polymer is one kind in polypropylene, polyethylene, polyester and polyamide；
2) laminated film is soaked in acetone soln, after acetylbutyrylcellulose in acetone extract outer membrane, outside
Tunic formation nano fibrous membrane, obtains the laminated film of nanofiber surface after drying.
Preferably, the basement membrane polymer is same material with outer layer copolymer.Basement membrane polymer and outer layers of polymer
Thing be the laminated film of nanofiber surface made from same material in two membranes composite effect more preferably, attaching it is tighter.
Preferably, the nanofiber film thickness is 50~100 μm, basement membrane thickness is 50~100 μm.
Preferably, the average diameter of nanofiber is 50~800nm in the nano fibrous membrane.
Preferably, the mass ratio of the outer layer film raw material and basement membrane polymer is 1:1~2.
The advantage of the invention is that：
1, compared with traditional composite membrane, outer membrane of the invention is nano fibrous membrane, and the specific surface area of outer layer is expanded
Tens times, the average diameter of nanofiber is 50~800nm in nano fibrous membrane, and nano level fiber has an excellent surface
Activity, if being handled by functional materials, the micron-sized nano fibrous membrane can adsorbed close functional materials so as to realizing spy
Different function, it is such as conductive, it is hydrophilic, it is hydrophobic, you can in special weaving face fabric, sense, the field such as ultracapacitor is applied.
2, after being combined by double-deck cast film machine, the composite effect of nano fibrous membrane and basement membrane is good, without viscous glutinous agent.
3, outer layer copolymer：Acetylbutyrylcellulose mass ratio is 1:9~4:When 6, acetylbutyrylcellulose as marine facies,
Outer layer copolymer is as island phase, and outer membrane passes through blending extrusion drawing-off, and calorific value is separated, and hot outer layer copolymer is dispersed into nanometer
Fibre structure, after by acetone, acetylbutyrylcellulose is extracted, outer membrane is changed into nano fibrous membrane, and is fixed on the table of basement membrane
Face, forms the composite membrane of nanofiber surface.When mass ratio is less than 1:9, the nano fibrous membrane of outer layer is excessively rare, works as mass ratio
More than 4:6, then acetylbutyrylcellulose is uniformly dispersed in outer layer copolymer, and can not form continuous phase, works as acetone
After extraction, it is impossible to form nanofibrous structures but form pore space structure.
