Abstract: Self-cleaning technology has attracted much attention due to its great potential in the sectors of antifouling, anticorrosion, energy saving and environmental protection, etc. This article discussed the theoretical foundations of super-hydrophobic self-cleaning surface and super-hydrophilic self-cleaning surface based on TiO₂ photocatalysis, and generally analyzed the progress and the applications of the two types of self-cleaning surfaces.Finally,the inadequacy and the future developments of the two types of self-cleanning surfaces were given.

Key words: super-hydrophobic, photocatalysis, super-hydrophilic, self-cleaning surface
