Atmospheric pressure plasma deposition of structurally well-defined polyacrylic acid films

Ultrasonic atomization of acrylic acid monomer into an atmospheric pressure glow discharge (APGD) leads to the deposition of structurally well-defined polymeric films. High retention of the carboxylic acid group has been verified by XPS and FT-IR spectroscopy. These films are found to exhibit low water contact angle values and display good adhesive and gas barrier performance.
