Problems solved by technology

[0003] However, SiO prepared by traditional methods 2 Superhydrophobic fabrics have general hydrophobic effect and poor washing resistance, and SiO 2 It is mainly attached to the surface of the fabric through physical adsorption, the adhesion fastness is poor, and the SiO attached after washing 2 will continue to fall off (Zou Rui, Xu Lihui, Shen Yong, Zhang Huifang, Li Qian. Constructing superhydrophobic surface of cotton fabric based on modified nano-silica[J]. Silicate Bulletin, 2014,33(12):3319-3324+ 3342)

Abstract

The invention discloses a silicon-dioxide superhydrophobic cotton fabric and a preparation method thereof. The preparation method comprises the following steps of: anionizing the cotton fabric, modifying with bovine serum albumin, modifying with nano silicon dioxide, modifying with bovine serum albumin and modifying with n-octyl trimethoxysilane. The silicon-dioxide superhydrophobic cotton fabricand the preparation method disclosed by the invention have the advantages of simple operation and mild reaction condition and the like, the defects of general hydrophobic effect and poor washability of SiO2 superhydrophobic fabric prepared by the traditional method are effectively improved; after SiO2 modification, the cotton fabric can obtain excellent superhydrophobicity and washability.

Description

technical field [0001] The invention relates to a silicon dioxide superhydrophobic cotton fabric and a preparation method thereof, belonging to the field of functional nanometer materials and textile materials. Background technique [0002] Superhydrophobicity refers to a special physical phenomenon in which the contact angle of water droplets on a solid surface exceeds 150°. Studies have shown that the microscopic rough structure and low surface energy of the material surface are the main reasons for the superhydrophobic phenomenon. Therefore, there are two methods for preparing superhydrophobic materials: one is to construct micro-nano structures on the surface of hydrophobic materials; the other is to modify low-surface-energy substances on the surface of micro-nano with layered structure. In view of the promising application prospects of superhydrophobic phenomena in the fields of waterproofing, oil / water separation, self-cleaning, and anti-icing, the preparation and ap...
