A Study on Design, Preparation of Refractory Ceramic Coating Materials Containing Nano-Nickel Particles, Properties of the Coating, Interface Reaction and Elements Diffusion between Substrate and the Coating
The results show that the optimal coating is prepared by 1% 3275, pH8. 0 and rubbing 1h and the particle can disperse well in organic membrane and the average diameter of the particle is 30nm by TEM detection.
According to the means and the functions of modification, the main methods of surface modification including mechanochemical modification, oxidation modification, surface chemical modification, encapsulation modification, coating modification and deposition modification were described.
PL analysis show that the Gd2O3:Eu still obtain well luminescent properties after coating silica.
After successfully prepared the nano- TiO_2, nano- CeO_2 coating TiO_2,the measurement and comparison of oxygen sensitivity and complex impedance have been carded out, and the results have been analyzed by thermodynamic and activity energy calculation.
Mordenite composite membranes were prepared by means of coating a porous α-alumina support with nanosized mordenite seeds followed by hydrothermal crystallization.
Results showed that optically variable pigments can be prepared by coating Cr2O3 on the surface of the pretreated TiO2-coated mica.
Effect of TiO2-coating on structure and electrochemical performance of LiCo0.2Ni0.4Mn0.4O2
LiCo0.2Ni0.4Mn0.4O2, as the cathode material for lithium ion batteries, was modified by TiO2-coating.
The results suggest that a small amount of TiO2-coating does not change the crystalline structure, but considerably improves the electrochemical performance of LiCo0.2Ni0.4Mn0.4O2 in terms of capacity delivery and cyclability.
