Styrene and methyl methacrylate diblock copolymers were synthesized by sequential living anionic polymerization, and the fractal-like hierarchical micro-/ nano-rough structures of the copolymer surfaces with superhydrophobicity were prepared by using phase separation method. When the ethanol content in the mixed solvents was 60%, the copolymer surfaces with water contact angle (WCA) of 156.7° and low contact angle hysteresis (7.1°) was obtained. The copolymer surfaces had excellent self-cleaning ability.
