介绍了膜表面光接枝技术的研究进展,并对接枝表面结构:表面形态和接枝链长度和密度作了综述.列举了接枝表面的性质,如接触角、吸附性、功能化、蛋白质固定化、环境敏感性等的变化. The research progress of optical grafting on the surface of the film was introduced, and the surface structure of the grafted film was also reviewed. The surface morphology and the length and density of the grafted chains were reviewed. The properties of grafted surfaces such as contact angle, adsorption, functionalization, Immobilization, environmental sensitivity and other changes.
