Abstract

The invention discloses titanium dioxide / baffeta with super-hydrophobic and self-cleaning functions. The titanium dioxide / baffeta is prepared by the steps of in-situ generating nanometer TiO2 particles in the baffeta, and cladding the TiO2 particles in the middle of BSA to obtain BSA / TiO2 / BSA modified baffeta; then soaking the BSA / TiO2 / BSA modified baffeta into a fluoroalkyl silane ethanol solution with the volume fraction being 1 to 10 percent for 1 to 24h, and after finishing reaction, repeatedly cleaning through deionized water, and vacuum drying to obtain the titanium dioxide / baffeta withthe super-hydrophobic and self-cleaning functions. A preparation method provided by the invention has the advantages of simplicity in operation, moderate reaction conditions and the like; the baffetahas an excellent super-hydrophobic performance, an excellent self-cleaning performance, an excellent anti-microbial performance, an excellent uvioresistant performance, an excellent photocatalysis performance, an excellent anti-wrinkle performance and excellent washing resistance.

Description

technical field [0001] The invention relates to a titanium dioxide / cotton fabric with superhydrophobic and self-cleaning functions, 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 types of methods for preparing superhydrophobic materials: one is to construct micro-nano structures on the surface of hydrophobic materials; . Zn sheets were modified by hydrothermal reaction and fluorosilane to construct superhydrophobic ZnO surface[J]. Acta Physicochemical Sinica, 2009,25(08):1593-1598). In view of the promising application prospects of superhydrophobic phenomena in the fields of waterproofing, oil...
