Abstract A facile method of phase separation was developed for fabricating the superhydrophobic polypropylene/titanium dioxide film. The prepared film showed superhydrophobicity with a high contact angle (169°) and low sliding angle (less than 4°). Moreover,the surface showed high contact angle (larger than 160°) for all the solution with pH value ranging from 1 to 14. Scanning electron microscopy images presented a kind of flower-like and micro/nano binary structure on the obtained polypropylene/titanium surface, which could trap air and form air cushion between water and the surface. Thus this micro/nano hierarchical structure played an important role in the formation of the superhydrophobicity. The superhydrophobic phenomenon of the prepared surface was analyzed according to Cassie theory, and it was proposed that only about 2.7% of the water contact surface was contacted with the substrate and the rest 97.3% was contacted with the air cushion.

Key words： superhydrophobic polypropylene titanium dioxide contact angle
