*Abstract: Fluorocarbon (FC) film deposition by plasma techniques has been used in numerous electrical, mechanical and biomedical applications due to the desirable physicochemical properties of FC films (i.e. low dielectric constant, surface energy, friction and wettability) as well as good hemocompatibility.

To take advantage of these attributes, researchers at UC Berkeley have investigated the dependence of FC film thickness, surface morphology and chemical behavior on the plasma power. These studies have resulted in the development of a method for synthesizing FC films on biopolymers such as low-density polyethylene.
