Improvement Of Antifogging Of Polyethylene Film By Ultraviolet Light Photografting Hydrophilic Monomer

Three new type monomers with muti-hydroxy and hydrophilic cation group were synthesized in this thesis. The effects of different photoinitiators,the concentration of photoinitiator and ultraviolet irradiation condition to the possibility of photografting and photografting percentage were also studied.The result show that under the experimental condition of this thesis.Type of the monomer with ally group can not be photografted to the surface of PE (polyethylene) film, other type of the monomer which is acrylate can be photografted a little.From FT-IR,it is benefit to the photografting when photoinitiator is benzophenone, irradiating from the back of the film,and irradiation time is a little longer,the influence of temperature need to study more.
