二氧化钛表面改性及其涂布膜光催化性能的研究
Surface Modification of Titanium Dioxide and Photocatalytic Activity of Its Coating Film
摘要
Abstract
Titanium dioxide was modified by coupling agents and characterized with grain size, zeta potential, etc, in order to obtain the optimum systhesis conditions.The results show that titanate coupling agent could successfully modify titanate powder, which increases the dispersion effect of the powder in polyvinyl alcohol.The coupled powders were dispersed in polyvinyl alcohol, and then coated on the BOPP film substrates, thus achieving the titanium dioxide coating films with photocatalytic properties.The above coating films were analyzed by micro gloss tester, friction coefficient tester, and fog degree instrument.The film shows good mechanical properties, dispersion effect with 1% of the modified powder.In the bactericidal effect was examined the film with 2% TiO2 can achive the best antibacterial effect of 99.2% and in the photodegradation experiment, the degradation rate increased nearly 70 times.关键词
