Fluorination of Polymeric Films by a Non Equilibrium Plasma at an Atmospheric Pressure

The polymerization of I-I difluoroethylene has been realized by a non equilibrium plasma at an atmospheric pressure on polymeric substrates such as polypropylene (PP). The graft copolymerizat ion onto the PP film was carried out when activating the polymeric substrate in the presence of argon. The structure of the polymeric film obtained depends on the residual oxygen in the plasma reactor. The role of the radicals which interfere in the grafting mechanisms of monomers onto polypropylene films has been studied.
