Problems solved by technology

Zhou et al. used the in-situ deposition method to introduce polyaniline (PANI) and perfluorooctanoic acid (PFOA) into cotton fibers to produce superhydrophobic and highly oleophobic cotton fabrics. However, the PFOA used in this method is difficult to degrade and is harmful to human body. Healthy, can not be industrialized production and application; for example, Liu et al. used dopamine to undergo self-polymerization under oxygen and weak alkali conditions, prepared biomimetic polydopamine@octadecylamine nanocapsules (PDA@ODA), and deposited it in situ On the surface of the fabric, a temperature-responsive superhydrophobic fabric was prepared; Xue et al. used dopamine to migrate molecular chains under oxygen plasma irradiation, and prepared an oxygen plasma-responsive hydrophobic polyester fabric
[0004] Although there are many methods for preparing super-hydrophobic surfaces, the above-mentioned methods have the disadvantages that the preparation process of super-hydrophobic surfaces is complicated and difficult for industrial application.
In addition, the superhydrophobic fabrics prepared by existing methods still have problems such as poor wear resistance, so it is urgent to find an industrialized and simple method for preparing wear-resistant superhydrophobic fabrics and superhydrophobic materials.

Abstract

The invention discloses a wearing-resistant super-hydrophobic fabric and a preparation method thereof and belongs to the field of super-hydrophobic fabrics. The preparation method comprises the following steps: firstly, on the basis of dopamine, and under oxygen and weak alkali conditions, carrying out a self-polymerization reaction so as to obtain a poly-dopamine buffer liquid, and depositing thedopamine on the surface of a fabric; secondly, carrying out roughening treatment on the surface of the fabric by using a nickel sulfate solution; and finally treating the surface of the fabric with alow surface energy substance, namely octadecylamine, thereby obtaining the super-hydrophobic fabric. The contact angle of the prepared super-hydrophobic fabric is up to 165 degrees, after 1000 timesof friction, the super-hydrophobic property is still maintained, high wearing resistance is achieved, the application range of the fabric can be greatly increased, and requirements of different fieldscan be met; and in addition, the strength in warp and weft directions of the fabric can be maintained, and application of the fabric is barely affected.

Description

technical field [0001] The invention relates to a wear-resistant superhydrophobic fabric and a preparation method thereof, belonging to the field of superhydrophobic fabrics. Background technique [0002] Inspired by the lotus leaf effect, super-hydrophobic surfaces have been favored by many researchers, because super-hydrophobic surfaces have strong practical and potential application values, such as self-cleaning, anti-icing, corrosion resistance, oil-water separation, anti-fog, etc. , People continue to develop different types of superhydrophobic materials to meet different application requirements through different methods, such as sol-gel method, template method, plasma technology, deposition method, electrospinning method, etc., such as Zhou et al. using dopamine, Silver nitrate and dodecyl mercaptan prepared superhydrophobic copper mesh, which was used in the field of oil-water separation; Bai et al. used the template method, using polystyrene as the template, cetyltr...
