| 摘 要： | 天然橡胶的性能与其组成中的C C双键有密切关系,由于C C双键的存在,为天然橡胶的改性提供了便利,大多数天然橡胶的改性方法,如氯化、氢氯化、环化、环氧化、接枝共聚等皆是建立在这一思路基础上的.White等1]认为接枝天然橡胶的目的是提高天然橡胶的机械强度,赋予特殊的功能.作

| Abstract: | A modification of natural rubber latex(NRL) grafted with perfluoroalkylethyl methacrylate(Zonyl TM) under sensitizer butyl acrylate(BA) by()~(60)Co 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. |
