Background
Due to excellent self-cleaning, antifouling, bacterial adhesion prevention, personal protection, corrosion prevention and other performances, the super-hydrophobic surface is applied to many fields. Commonly used superhydrophobic surfaces are typically prepared by structuring the rough structure and using extremely low surface energies, wherein fluorochemicals, while susceptible to excellent barrier properties, are limited by their difficulty in degradation and toxic bio-accumulation. In addition, the super-hydrophobic coating, including the roughness of the nanoparticles, is easily peeled off or rapidly lost by washing with water, rubbing, etc., so that it is very necessary to improve the durability of the super-hydrophobic coating, especially for wearable textiles, and thus chemical grafting is a great concern in the aspect of surface chemical grafting modification. Meanwhile, due to the problems of long process preparation, pretreatment and the like, the super-hydrophobic coating is difficult to be applied in actual large-scale industrial production, so that the super-hydrophobic coating which is universal, one-step and short-process and has excellent durability and surface protection performance is urgently needed.

In the embodiment, 3-mercaptopropyltriethoxysilane is not added, the finished fabric can meet the super-hydrophobic requirement, but the hydrophobic effect is poorer than that of the added 3-mercaptopropyltriethoxysilane, and the finishing effect of the process can be influenced to a certain extent by the 3-mercaptopropyltriethoxysilane.
