Abstract

Poly(N-isopropyl acrylamide) (pNIPAM) undergoes a sharp property change in response to a moderate thermal stimulus at physiologic temperatures. In this work, we constructed a radio frequency (RF) plasma reactor for the plasma polymerization of pNIPAM. RF deposition is a method that coats surfaces of any geometry producing surfaces that are sterile and uniform, making this technique useful for forming biocompatible films. The films generated are characterized using X-ray photoelectron spectroscopy, contact angles, cell culture, and interferometry. We find that a plasma with a decreasing series of power settings (i.e., from 100 to 1 W) at a pressure of 140 mTorr yields the most favorable results.
