摘要
三元光敏引发体系不仅能生成阳离子,也能生成自由基,进而引发单体有效地聚合。含该引发体系的口腔材料在可见光照射下有较高的引发效率和足够高的单体转化率,兼备自由基型和阳离子型光引发剂的优点。下面着重就可见光三元光敏引发体系的组成、聚合特点以及发展趋势作一综述。
Three-component initiator systems can generate both cations and free-radicals, and initiate monomers to polymerize effectively. The dental materials containing these initiator systems show better initiating efficiency and sufficient degree of monomer conversion under visible light irradiation. These initiator systems have advantages both of cationic initiators and of free-radical intiators, The paper is to especially review the components, the characteristics and the developmental trends of the three-component visible-light photoinitiator system.
