低收缩率光固化反应研究进展

Research Progress in Photopolymerization with Low Shrinkage

光固化技术具有高效、适应性广、经济、节能、环境友好的"5E"特点,在过去的几十年间,得到迅速发展。但是在聚合过程中会发生体积收缩现象,严重阻碍其应用。文章简要介绍了体积收缩产生的原因及后果,并对减小收缩率的方法进行了综述。

The photopolymerization has developed rapidly for decades, which is efficient, enabling, economical, energy saving, and environmental friendly. However, volume shrinkage occurring in the polymerization is a major drawback for current applications. The causes and consequences of shrinkage have been introduced briefly. The method of reducing polymerization shrinkage was reviewed.
