Fluorocarbon films using a monomer, 1H, 1H, 2H‐perfluoro–1‐dodecene were deposited in a continuous radio frequency (RF) glow discharge, the process was carried out in a parallel‐plate RF discharge onto stainless steel reactor in order to produce coating with a water‐and oil–repellent surface. Fourier‐Transform Infrared spectroscopy (FT‐IR) and X‐ray Photoelectron Spectroscopy (XPS) revealed that the films obtained contain mainly perfluoromethylene (CF2) species. Film wettability was tested using water and hydrocarbon liquids for contact angle measurements, furthermore surface energy was also calculated. Oil‐repellency was found to increase as the amount of CF2 species increases in the film structure. Film morphology was studied by Atomic Force Microscopy (AFM), films showing an usual morphology from that typical of Plasma Polymerised Fluorocarbon (PPFC) films. The combination of the low surface energy coating and the surface morphology produces materials which are both water and oil repellency.

Polymers are widely used in a great number of applications because of their many advantages. For applications requiring optical and conductive properties, the choice of a suitable polymer is limited to polymers with a conjugated chemical structure such as polyacetylene, polypyrrole, and polythiophene. Very thin film of polythiophene can be deposited by electrochemical procedures and plasma polymerization. A plasma consists of a variety of reactive species (electrons, ions, radicals, etc.) and therefore many different reactions can occur. The aim of this study is to produce poly(3‐methylthiophene) using the plasma technology in pulsed wave. The influence of RF power on the film properties will be evaluated.
