Abstract

The invention relates to a method for low-temperature preparation of an anatase titanium dioxide film on the surface of cotton fabric, which comprises the following steps: (1) mixing absolute ethyl alcohol, glacial acetic acid and n-tetrabutyl titanate, then slowly dropwise adding the mixture into a mixed solution of acetic acid with a pH value of 2.5-3 and water for hydrolysis, and severely stirring to form titanium dioxide sol; and (2) soaking the cotton fabric in the titanium dioxide sol for 2-3 minutes, soaking twice and rolling twice; pre-drying at 70-90 DEG C for 3-5 minutes; and steaming at 80-100 DEG C for 2-3 hours. The preparation method provided by the invention is simple and does not need an adhesive or high-temperature curing treatment; through a conventional soaking-rolling-steaming technology, an anatase film with good binding strength, high crystallinity and excellent photocatalytic performance is formed on the surface of the cotton fabric; and the method can be applied to the purification of in-car and indoor air, self-cleaning of fabric and the like.

Description

technical field [0001] The invention belongs to the field of preparation of titanium dioxide thin films, in particular to a method for preparing anatase titanium dioxide thin films on the surface of cotton fabrics at low temperature. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's functional requirements for textiles are not limited to the most basic wearable performance. favor. For textile printing and dyeing enterprises, endowing textiles with special functions plays a vital role in improving product quality and increasing product added value. Photocatalytic material TiO 2 (especially the anatase crystal form) has high photocatalytic activity, good stability and heat resistance, non-toxic and cheap to the human body, and has been widely known. The application of nano photocatalytic materials in textiles can endow fabric Photocatalytic self-cleaning, UV resistance, VOC degradation and other func...
