STUDIES ON GAS PHASE GRAFT COPOLYMERIZATION OF IRRADIATED FLUOROPOLYMERS |
| |
| Abstract: | The surface and cross section structure of the PTFE AA copolymer have been studied with the help of SEM and POM investigation,and the relationship between the film thickness and grafting degree has been analyzed,so that the graft copolymerization of gaseous acrylic acid onto irradiated PTFE has been confirmed to be diffusion controled reaction.Therefore,both the surface wettability and the adhensive strength have also been investigated to figure out the future application of the modified film. |
