Description
Technical Field
The invention relates to the technical field of functional materials, in particular to a preparation method of a high-thermal-conductivity super-amphiphobic fabric with liquid drop one-way permeability.
Background
The one-way permeability of liquid droplets is widely found in nature, for example, beetle backs, spider webs, cactus, and the like. In recent years, fabrics made by using the characteristics similar to liquid diodes can directionally transport sweat on the surface of human skin to the outer side of clothes, so that the skin can keep dry and comfortable temperature, and the fabric is a focus of attention in the fields of functional garment manufacturing and special wettability fabrics. The material with the liquid drop one-way permeability is mainly compounded by a plurality of layers of materials with different wettabilities through the modes of hot pressing, spinning, spraying and the like, and can also be prepared through asymmetric chemical modification.
However, although the current commercial cloth can realize unidirectional transportation of liquid drops on the inner side to the outer side, the pollution of external liquid cannot be avoided. Meanwhile, sweat on the surface of the skin is continuously conveyed to the outer side of the cloth, and the sweat cannot be rapidly removed from the outer side of the cloth, so that the cloth is gradually heavier, the sweat conveying speed is reduced, the application of the cloth is greatly limited, the oil pollution resistance, the heat conductivity and the air permeability of the cloth are poor, and the preparation process is complex.
Disclosure of Invention
The invention provides a preparation method of a high-thermal-conductivity super-amphiphobic fabric with unidirectional liquid drop permeability, and aims to enable the fabric to have the unidirectional liquid drop permeability and also have the characteristics of rapid dehydration, oil resistance and rapid thermal conductivity.
The above purpose is realized by the following technical scheme:
a preparation method of a high-thermal-conductivity super-amphiphobic fabric with liquid drop one-way permeability comprises the following steps:
s1, soaking the fabric in an organic solvent for cleaning, cleaning and drying;
s2, soaking the dried fabric in an acetone solution containing boron nitride with the concentration of (5 to 30) g/L and alpha-cyanoacrylate with the concentration of (2 to 12) g/L, and drying after soaking; wherein the particle size of the used boron nitride micro-nano particles is 2 μm.
S3, repeatedly soaking the fabric in the cationic polyelectrolyte solution and the anionic polyelectrolyte solution; preferably 5 times, and the specific sequence is cationic polyelectrolyte solution-anionic polyelectrolyte solution-cationic polyelectrolyte solution. Wherein the cationic polyelectrolyte solution is polydiallyldimethylammonium chloride solution, polyethyleneimine solution, chitosan solution or polyacrylamide hydrochloride solution, the anionic polyelectrolyte solution is sodium polystyrene sulfonate solution or sodium alginate solution, the concentrations of the cationic polyelectrolyte solution and the anionic polyelectrolyte solution are (1 to 3) mg/ml, and both the cationic polyelectrolyte solution and the anionic polyelectrolyte solution contain sodium chloride with the concentration of (0.5 to 1.2) mol/L, preferably, the fabric is washed by plasma water for one minute before the cationic polyelectrolyte solution and soaking;
s4, soaking the fabric in a perfluorooctanoic acid ethanol solution, and drying after soaking;
s5, covering a mask with a hole array on one surface of the fabric and irradiating ultraviolet light; the wavelength is less than or equal to 254nm when the lamp is irradiated, the irradiation time is 30 to 45min when the lamp is irradiated at 180W, and about 4 hours are required when the lamp is irradiated at 40 to 60W.

Detailed Description
Example 1:
a preparation method of a high-thermal-conductivity super-amphiphobic fabric with liquid drop one-way permeability comprises the following steps:
step 1, soaking white or colored knitted or woven cotton fabric in organic solution, washing for 5-20 min (preferably for 15min) by ultrasonic oscillation, and drying at 80 ℃ in an air circulation drying oven; wherein the organic solution is high-polarity solution such as ethylene glycol, methanol and/or deionized water, preferably mixed solution of ethanol and acetone;
step 2, soaking the dried fabric in an acetone solution containing boron nitride and alpha-ethyl cyanoacrylate, wherein the concentration of the boron nitride is 12g/L, the concentration of the alpha-ethyl cyanoacrylate is 5g/L, and taking out and drying the fabric after ultrasonic oscillation is carried out for 5 to 20min (preferably 10 min);
step 3, repeatedly soaking the fabric in the poly (diallyldimethylammonium chloride) solution and the sodium polystyrene sulfonate solution for 5 times in sequence, preferably washing the fabric with plasma water for one minute before soaking the poly (diallyldimethylammonium chloride) solution for each time;
step 4, soaking the fabric treated in the step 3 in 0.1mol/l of perfluorooctanoic acid ethanol solution;
and 5, taking out the fabric treated in the step 4, drying the fabric in an air circulation drying oven at 60-120 ℃ (preferably 80 ℃) for 5-15 minutes (preferably 15 minutes), covering a mask with a hole array with the diameter of less than or equal to 3mm (preferably 2mm) and the distance of more than or equal to 1.5mm (preferably 10mm) on one surface of the fabric, and irradiating the mask with ultraviolet light of 254nm and 180W for 45 minutes to finally obtain the high-heat-conduction super-amphiphobic fabric with the liquid drop one-way permeability, wherein the single-way permeability effect with the optimal value is adopted in the step.
The particle size of the used boron nitride micro-nano particles is 2 mu m;
the concentrations of the cationic polyelectrolyte solution and the anionic polyelectrolyte solution are both 1mg/ml, and both contain 1mol/L sodium chloride;
as shown in fig. 1, the ultraviolet light irradiated portion of the fabric surface exhibits gradient wettability in the thickness direction, and the surface exhibits super-hydrophilicity and super-lipophobicity at the irradiated point, but exhibits super-amphiphobicity as a whole.
Example 2:
combining with the example 1, the poly (diallyldimethylammonium chloride) solution in the step 3 is replaced by a polyethyleneimine solution.
The ultraviolet irradiation time of 180W in step 5 was replaced by 30min from 45 minutes.
As shown in fig. 2, the reverse and front sides of the fabric prepared in this example all have the amphiphobic property, and after the fabric is taken out from water, only the points of the front side irradiated by ultraviolet light are adhered with water drops, and the water drops can be thrown away. Fig. 2c shows the dynamic process of the unidirectional penetration of the droplets, and it can be seen that the droplets do not flatten on the surface after the unidirectional penetration of the fabric, but automatically slide off the fabric surface when the droplets accumulate to a certain size.
Example 3:
in combination with example 1, the 180W UV light in step 5 was irradiated for 30 min.
As shown in fig. 3, it can be seen from the electron microscope images of the front side illumination point, the front side mask covered part and the back side of the fabric prepared in this example that the boron nitride particles are uniformly distributed on the fabric fibers, so that the overall thermal conductivity of the fabric is improved.
This application adopts polyelectrolyte layer upon layer equipment's strategy, makes the fabric possess super amphiphobic characteristic through combining fluorine-containing ion to illumination makes through covering behind the mask:
(1) not only can prevent the outside from being soaked by water, but also has double-sided oil resistance, can prevent various oils from polluting fabrics and is easy to clean.
(2) Compared with the common Janus fabric, sweat or water transported from the inner side to the outer side can be quickly removed instead of being directly absorbed by the outer side, the lighter weight of the fabric is kept, and the speed of liquid drop permeation is not influenced.
(3) Compared with the existing commercial fabric, the fabric has the advantages that the heat dissipation is faster due to the addition of the boron nitride particles with good heat conductivity, and the function of unidirectional sweat conveying is combined, so that the temperature of a person can be rapidly reduced after the person moves.
(4) The preparation process disclosed by the invention is simple to operate, has low requirements on factors such as environment and equipment, is good in repeatability, and is suitable for large-scale production.
