Effect of Pore Size on the Hydrophilicity in Dark of TiO2 films
Mesoporous Ti02 films was prepared by evaporation-induced self-assembly and dip-coating method. And the pore size of the TiOa films is adjusted by controlling the molar ratio of H2O/TiO2 (H value). Water contact angle was chosen to represent the hydrophilic property, and XRD and AFM were carried out to characterize the films. With the increase of H value, the pore size increased firstly then decreased. And when H is 15, the pore size is the biggest, which hydrophilicity in dark is the best too. With the extention of the non-irridation time, the hydrophilicity is worse. And the reason may be ascribed to the adsorption of organic matter in air.
