Recent Advances in Surface Modification of PET Materials

Many methods of surface modification of PET were described. Among them are irradiation with high-energy particles, chemical 

Polymer surfaces could be modified both chemically and physically when they are exposed to a physical treatment like plasma, corona discharge, flame treatment, UV irradiation or electron and neutron beam irradiation (41)... 

Glycopolymers were recently grafted onto PET fibers by double plasma treatment in order to obtain a surface compatible with biological material. The first step is activation of the PET surface by argon plasma treatment leading to the formation of radicals by scission of the chemical bonds. Then, fibers are exposed to air in order to form (hydro)peroxides functions. The activated fibers are dipped in glycomonomers solutions and dried. A second plasma treatment is applied to polymerize the monomers adsorbed on fibers (43).
