摘要:
Glycidyl methacrylate was grafted onto polyethylene films using a preirradiation method with gamma rays. The effect of absorbed dose, monomer concentration, and reaction time on the degree of grafting was determined. The grafted samples were verified by FTIR-ATR spectroscopy. beta-Cyclodextrin was immobilized onto polypropylene modified with glycidyl methacrylate, and the ability of the cavities of beta-cyclodextrin to form inclusion complexes was demonstrated using the typically organic compound approach with in-toluic acid (3-MBA) as a probe.
