Abstract

The photografting of acrylamide onto cellulose acetate films using light of wavelength > 380 nm is discussed. The semiconducting properties of colloidal Fe2O3 (bandgap 2.2 eV) is used for photosensitizing the reaction. Degree of grafting is dependent upon the concentration of the photosensitizer as well as that of the monomer. Methyl viologen (MV2+) is used to prevent e−h+ recombination.
