Preparation of the Self-Cleaning and Luminous PVC Membrane Structure Material and its Properties Study
Coating nano-sized TiO2 and SrAl2O4:Eu2 +, Dy3 + lanthanum luminous material on PVC membrane structure material to change its surface properties, then study the self-cleaning and luminous properties after the surface treatment .The results show that: the PVC membrane structure material can degrade the organic matter of methylene blue and oleic acid and has good dirt-pick property after the surface treatment with nano-sized TiO2 and SrAl2O4:Eu2 +, Dy3 +lanthanum luminous material. The photodegradation efficiency reaches to the highest when the TiO2 concentration is 1% and coated for three layer. In addition, the SrAl2O4:Eu2 +, Dy3+ lanthanum luminous material can not only endow the PVC membrane structure material glowing function in the darkness, but also ,it can improves the photodegrading efficiency of the PVC membrane structure material. With the increasing of the concentration of luminous materials, the photodegrading efficiency is increased.
