Description
Technical field
The present invention relates to field of textiles and oily water separation technique field, more particularly to a kind of hydrophobic cotton fabric and its preparation
Methods and applications.
Background technology
In nature, the contact angle of many super hydrophobic materials is both greater than 150 °, and most common is exactly lotus leaf and mosquito eye
Eyeball.At present, super hydrophobic material is applied to many fields, such as water-oil separating, drag reduction, automatically cleaning and antifouling.People's profit
Super hydrophobic surface, such as vapor phase deposition method, plasma etching, sol-gel process and infusion process are simulated with many methods.So
And from the point of view of environment and sustainable development, there are many defects for existing method：Such as need complexity technique, organic solvent and
The use of fluorine-containing material (generally all poisonous, difficult degradation), the prices of raw materials are expensive etc..Therefore, there is an urgent need for a kind of simple, environment friend at present
Good and low cost method prepares super hydrophobic material.
Cotton is widespread in nature, and in textile industry.Its is cheap, is readily available, and cotton fabric is
It is used in a variety of study on the modification, including uvioresistant and fire-retardant, or even resists and electrochemistry.In order to meet that people are growing
Need, the preparation of functionalization cotton fabric has been widely studied.Cotton fabric is itself had as scale texture, can be in secondary roughness
On the basis of add two level Nanometer Roughness or low-surface energy substance, prepare super-hydrophobic cotton fabric.Meanwhile inspired by nature
Phenomenon be also widely studied, it is representational have by mussel catechol inspire method for preparing super-hydrophobic surface.This method one
As be divided into three steps：By the autohemagglutination of catechol, poly- catechol face coat is constructed；Prepared and received by the reproducibility of autopolymer
Rice microroughness；H is carried by Michael's addition or schiff base reaction grafting2The material of the low-surface-energy of N- or HS- groups.
However, above-mentioned reaction often uses dopamine, and preparation process very time-consuming when small (generally 24) and of high cost.Therefore explore
Preparing cheap, environmental-friendly, the simple super-hydrophobic cotton fabric of preparation process has great significance.
In recent years, the research of the material of water-oil separating is very extensive, but current water-oil separating material is expensive, material
The preparation process of material itself is complicated, and separative efficiency also has deficiency, and separation process waste of energy, and therefore, research can be continuously high
The oily water separation technique of effect has very high application value in practical applications.
The content of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of hydrophobic cotton fabric and preparation method thereof and answer
With method of the invention is simple and environmentally-friendly, efficient, and reaction condition is gentle, and prepared hydrophobic cotton fabric has in various environment
