Surface modification of polymers by graft polymerization is a relatively new method for covalent immobilization of macromolecular chains on a polymer substrate. Our article is concerned with surface graft polymerization of various monomers (ionic and nonionic) onto fabrics, fibers, and films by use of simultaneous UV irradiation. For this surface modification, a polymer substrate to be grafted is immersed in a monomer solution containing a small amount of meta-sodium periodate (NaIO₄) or riboflavin, followed by exposure to UV radiation without degassing. Principle factors affecting the surface photo-graft polymerization include the concentrations of NaIO₄ and monomer, and the UV irradiation time. This article involves both the characterization of grafted surfaces and the interfacial properties of grafted surface/water. They were studied on the basis of attenuated total internal reflectance Fourier-transform infra-red spectroscopy, atomic force microscopy, contact angle, and zeta potential measurements. We described also applications of the graft polymerization for production of polymer surfaces possessing excellent biocompatibility, anti-statics, and lubrication.
