In Situ Growth of Hydrophobic TiO2 on Calocedrus macrolepis Kurz Wood Surface Using a Cosolvent-Controlled Hydrothermal Method
This paper examined the in situ growth of hydrophobic anatase TiO2 coating on wood surface using a cosolvent-controlled hydrothermal method. EDXA, FTIR and XRD analysis confirmed that the growth of TiO2 coating on wood surface was bonded to hydrocarbon chains. The relative contact angle of before and after treated wood sample was changed from 46.5o to 136.8o with the examination of contact angle analyzer, which induced a change of the untreated wood surface from hydrophilic to hydrophobic. As observed on SEM image, some slippery TiO2 spheres with about 300-600 nm in diameter evenly dispersed on treated wood surface.
