Results show that the optimum encapsulation conditions are chloroform as solvent,a reactive temperature of(35±5)℃,pH value of 8.5 and a reaction time of 6 h,in which the homogenous and compact maleic anhydride coating of SrAl2O4:Eu2+,Dy3+ phosphor is formed. Thereby,the water resistance of the composite phosphor is improved.
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.
