摘要
辐射接枝是聚合物表面改性的重要方法之一。本工作讨论了接枝单体和基材的性质、溶剂、酸、阻聚剂以及其它添加剂对聚合物辐射接枝反应的影响,介绍了利用光学显微镜、扫描电子显微镜原子力显微镜、凝胶色谱、X射线光电子能谱、拉曼光谱、红外光谱等所取得的接枝条件对接枝层的形态结构及接枝链长短研究结果。对近年来出现的能精确控制接枝链分子量和结构的活性聚合方法也作了简单介绍。
Radiation-induced graft copolymerization is an important technologies for surface modification of polymers. In this paper, we give a review on recent progresses in this field of research. Factors affecting degree of the grafting, such as the monomer and base polymer, the solvent, the initiator and other additives, are discussed. Studies on morphologies of the grafted layers and distributions of the grafted molecular chains characterized by OM （Optical microscopy）, SEM （Scanning electron microscopy）, AFM （Atomic force microscopy）, GPC （Gel permeation chromatography）, XPS （X-ray photoelectron spectroscopy）, Raman and IR （Infra-red） spectroscopy are reviewed. The emerging grafting method of living polymerization induced by ionizing radiations, with which one is able to accurately control molecular weight and structure of the grafted molecular chains, is also briefly introduced.
