摘要
The photoactivity of TiO2 catalyses coating degradation. The hydrophilicity and level of surface moisture on TiO2 particles were found to be directly proportional to photoactivity. Thus, if TiO2 can be kept dry in a paint its photoactivity should be reduced. Notably, a fully calcined TiO2 sample showed no hydrophilicity and negligible photoactivity.
