Diethyl(1,10-phenanthroline-N1, N10)zinc Initiated Grafting of Styrene on Polypropylene/Polyethylene

Styrene was grafted onto the surface of polypropylene (PP)/polyethylene (PE) films through direct radical polymerization using diethyl(1,10-phenanthroline-N1, N10)zinc (Phen-DEZ) and oxygen molecules as the radical initiators. The grafting of styrene on the PP/PE surface was confirmed by FT-IR, Raman, UV-Vis, atomic force microscope (AFM) and thermogravimetric analysis (TGA).
