Gas Recognition Films Fabricated by Microplasma Technology

Abstract

We developed a novel fabrication method of on-demand polymer film synthesis onto a substrate under atmospheric pressure using microplasma polymerization with a laboratory-made torch-type microplasma polymerization apparatus. We used styrene as model monomer for selection of polymerization condition of microplasma-polymerization and evaluation of microplasma-polymerized (MPP-) styrene films. These films were characterized using data FT-IR, EDX, contact angle, and gas sorption property using QCM technique. Characterization results of FT-IR, contact angle, and EDX suggest that MPP-styrene films were oxidized. Results showed that gas sorption properties of MPP-styrene films were controllable by polymerization parameters of VHF power or concentration of monomer gas.
