【Abstract】 A modification of natural rubber latex（NRL） grafted with perfluoroalkylethyl methacrylate（Zonyl TM） under sensitizer butyl acrylate（BA） by（）⁶⁰Co gamma ray emulsion copolymerization was presented in this paper.The components of the NRL films were studied by Fourier-transfer infrared（FT-IR） spectrometry.The contact angle（CA） analysis showed that the NRL films exhibited a high water contact angle after modification,which changed of 81.1 degree to 110 degree.The surface analysis of X-ray photoelectron spectroscopy（XPS） revealed that the fluorinated segments were preferentially self-organized at the film-air surface.Furthermore,the effect of the Zonyl TM and BA contents on the properties of NRL films was discussed by CA in detail.It showed that the NRL films with 0.94 wt% Zonyl TM and 2.77 wt% or 4.55 wt% BA had better modification effect than the others.更多还原
