Abstract
In this paper, a simple method of preparing superhydrophobic surface was proposed by nanomolding with lotus leaf as template. After two-step molding, micro and nano composite structures were transferred to poly(dimethylsiloxane) (PDMS) negative-mold and follow up positive replica of Parafilm® M, and there is no need of additional anti-stiction coating during demolding. After replication, PDMS negative-mold remained clean so as to reuse without repreparation. The results show that Parafilm® M replica, a wax material with transferred micro and nano structures could produce lotus-like superhydrophobic surface with contact angle larger than 150 degree and low hysteresis. © 2006 Society for Chemistry and Micro-Nano Systems.
