SEMICONDUCTOR PHOTOSENSITIZED GRAFTING - PHYSICOCHEMICAL STUDIES ON ACRYLAMIDE GRAFTED CA FILMS

Grafting of acrylamide on cellulose acetate films was carried out in v isible light using colloidal Fe2O3 as the photosensitizer. pH studies show that grafting is maximum at pH 6.0. Fourier transform infrared st udies show that grafting occurs through the vinyl group of acrylamide. Grafting changes the tensile strength of the films, which has been pr obed through acoustic studies. X-ray diffraction studies show the amor phous nature of these films even after grafting.
