The construction methods for self-cleaning materials are systematically sorted out according to various literatures,and summarized upon different hydrophilicity of self-cleaning surfaces(dividing into super-hydrophobic,super-hydrophilic,super-hydrophobic/super-hydrophilic transformable),and different surface construction mechanisms.Some development ideas are suggested for overcoming the difficulties faced by self-cleaning materials at present.
