Overcoming of nanoscale adhesion by electrostatic induction
Polymeric nanopillar array was replicated by dipping of anodic aluminum oxide template into amorphous fluoropolymer (Teflon (R): DuPont (TM)) solution. The prepared anodic aluminum oxide template has the self-ordered nanohole structures with the high-aspect-ratio (more than 100). To obtain Teflon nanopillar array, Teflon replication based on the dipping method was used, with a 6 wt% Teflon solution. During the replication, the adhesion problem by the van der Waals interaction at micro/nanoscale was overcome by electrostatic induction. (C) 2008 Elsevier B.V. All rights reserved.
