FABRICATION AND CHARACTERIZATION OF NANO-STRUCTURING POLYMERIC SURFACES FOR MEMS APPLICATIONS

摘要

Using external stimuli to control surface properties, such as surface topology or wettability, has been of great interest. This paper presents the fabrication, mechanism, and analysis of an active method that modulates surface nano-topology and wettability of polymeric films. The polymeric film possesses the unique property of electrical potential-induced wettability conversion: when its doping level is electrically altered, the interstitial ions are incorporated or released, causing the polymer network to stretch and thereby changing its surface morphology.
