Abstract

The invention discloses a method for preparing a nano titanium dioxide thin film on the surface of a dacron. The method provided by the invention comprises the following steps of: firstly, ultrasonically vibrating and washing the dacron to be treated for 10-30 min at a temperature in a range of 60-90 DEG C by utilizing treating fluid under the conditions that the frequency is 28 kHz and the poweris 100 w; then drying the dacron for future use; secondly, utilizing titanium sulfate solution and urea solution to subject the dacron to a hydro-thermal reaction; finally, washing the dacron by utilizing the washing solution in the bath ratio of 1 to 30-50 for 15-30 min at a temperature of 100 DEG C; repeatedly washing the dacron by hot water and cold water and then drying to prepare the nano titanium dioxide thin film on the surface of the dacron. The method for preparing the nano titanium dioxide thin film on the surface of the dacron provided by the invention saves raw materials, is convenient for operating and has a good use effect; and the washing resistance of the modified dacron is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of functional textile materials, and relates to a surface treatment method for polyester fabrics, in particular to a method for preparing a nanometer titanium dioxide film on the surface of polyester fabrics. Background technique [0002] Among many semiconductor functional inorganic materials, nano-titanium dioxide powder has broad application prospects in the fields of photocatalysis, dyes, industrial catalysis, lithium-ion secondary battery materials and photosensitive batteries due to its good photocatalytic activity and electrical properties. It has become the focus and hotspot of current nanotechnology research. The more prominent problem of nano-titanium dioxide powder materials is that they are easy to agglomerate, which leads to a decrease in photocatalytic activity and has a great impact on other properties. Therefore, the synthesis of monodisperse high-quality nano-TiO2 powder is the focus of res...
