Two-dimensional titanium dioxide/graphene flaky modified self cleaning fabric and preparation method thereof

Abstract

The invention provides a two-dimensional titanium dioxide / graphene flaky modified self cleaning fabric and a preparation method thereof. According to the method, a titanium source and a triblock copolymer F127 are added into a tetrahydrofuran solution; the pH is regulated to an acid state; continuous stirring is performed until the solvent is completely volatilized; titanium source precursor gel is obtained; the titanium source precursor gel is added into a polylol mixed solution; after the uniform mixing, an oxidized graphene solution is dripped; uniform mixing is performed; the materials aretransferred into a hydrothermal reaction kettle; hydrothermal reaction is performed; after the centrifugal separation and cleaning, a graphene modified two-dimensional titanium dioxide flaky materialis obtained; then, the graphene modified two-dimensional titanium dioxide flaky material is dispersed into a flexible substrate solvent; the material is applied or sprayed onto the surface of the fabric; drying is performed; then, through ethanol water vapor treatment, the two-dimensional titanium dioxide / graphene flaky modified self cleaning fabric is obtained. The graphene modified two-dimensional titanium dioxide flaky materials are uniformly distributed in the flexible substrate nanometer layer on the surface of the prepared fabric; the fabric has good ventilation performance, comfort performance and good self cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a two-dimensional titanium dioxide / graphene flake modified self-cleaning fabric and a preparation method thereof. Background technique [0002] Self-cleaning textiles originated from the self-cleaning properties of fur on the surface of animals and the surface of some plant leaves. In recent years, studies have found that the modification of textiles with titanium dioxide coating can endow textiles with self-cleaning properties, usually under low temperature conditions. The gel method combines nano-titanium dioxide to treat the textiles to form a layer of titanium dioxide film on the textiles. The photocatalytic performance of the titanium dioxide film under the irradiation of ultraviolet light or light is used to achieve antibacterial and antifouling effects, so as to achieve the purpose of self-cleaning. [0003] At present, there are many studies on self-...

AI Technical Summary

Problems solved by technology

It can be seen from the above prior art that most of the nano-titanium dioxide in self-cleaning fabrics currently prepared are nano-titanium dioxide particles, and only nano-titanium dioxide with visible light catalytic activity is combined with other materials to make a finishing agent or spinning solution. There are few studies on the structure of titanium dioxide, the thickness of nano-titanium dioxide-modified coatings, and the bonding between coatings and textiles.
