摘要：

We present a facile method for the fabrication of a stable superhydrophobic polypropylene surface in atmosphere using acetone as the non-solvent. The obtained surface exhibited superhydrophobicity with a higher static contact angle (160 degrees +/- 1.9 degrees)and a lower sliding angle (less than 4 degrees +/- 1.9 degrees). Moreover, in different aqueous solutions with pH value ranging from 2 to 12, all contact angles observed were beyond 150 degrees. Scanning electron microscopy images showed the as-fabricated surface had bird-nest-like micro/nano-binary structures similar to those of lotus leaves, which can trap air and form air cushion between water and the surface. The method offers potential opportunities to prepare superhydrophobic surfaces on common plastics.
