Kinetics Study on Remote Argon Plasma-Induced Graft Polymerization of Acrylic Acid onto PTFE Films
In this paper, we introduced carboxylic groups on the surface of poly (tetrafluoroethylene) (PTFE) with the aid of remote argon plasma treatment and the post- grafting of acrylic acid (AAc) in an aqueous solution. We chose different parameters of remote plasma treatment to get the optimum condition for grafting co-polymerization AAc on the PTFE surface. The influence of the grafting reaction conditions on the grafting degree was investigated. The apparent activation energy of the grafting obtained from an Arrhenius plot was 27.2kJ/mol. The surface hydrophilicity of the PTFE film was characterized with the water contact angle meter and the surface free energy. The hydrophilicity of the PTFE film surface was greatly enhanced. The time-dependent activity of the grafted surface was better than that of the plasma treated film.
