Preparation And Performance Characterization Of Super Hydrophilic Coating

In our life, with the improvement of science and technology, all kinds of glass buildings can be seen everywhere,However, how to keep it clean and beautiful the phenomenon which we must face; The droplets will form a water film on the glass surface,without interfering with the line of sight of clarity; How to make artificial ceramic teeth clean, and so on all,that are needed human beings to solve the problems. Then Super hydrophilic coating research, which will be to solve the problem. This paper mainly introduces the composition and use of the super-hydrophilic coating. The major component of super hydrophilic coating is nano-titanium dioxide, and its photo catalytic performance is good, which can thoroughly decomposed the pollutants of the surface of the substrate. The good hydrophilicity of nanometer titanium dioxide,which can solve the phenomenon of atomization, but the response spectrum in the UV region, but the visible light utilization rate is low. This chapter mainly discusses how to improve the photo catalysis of the nano-meter titanium dioxide in the visible region of the performance and the wettability of water droplets.This chapter mainly introduces the preparation of nano-titanium dioxide and doping modification,the test is analyed and discussed.The nano-composite photo-catalyst Fe3+-TiO₂,Cu²⁺-TiO₂, and P5+-TiO₂, which were preparated by the method of Sol-Gel, which were tested by XRD, SEM,TG-DTA, Contact angle meter and UV-Vis.The influence factors of the preparation process, photocatalytic properties and hydrophilic of the composite photocatalyst were studied by the scientific researcher.
