深层光固化研究进展

Research progress in deep photocuring

光固化体系深层区域无法受到光的辐射,常常造成转化率低的问题。该文综述了目前常用的几种解决方法,包括常规的增加单体官能度、加入交联剂以及改进光引发剂体系,还介绍了新颖的上/下转换发光、可见光/红外光固化、双光子固化方法。概述总结了每种方法的优缺点,旨在为今后的研究提供方向。

The deep area of photocuring system can’t be radiated by light, which usually results in low conversion rate. Several commonly used methods to solve the problem are described, including conventionally increasing monomer function, adding crosslinking agents, and improving photoinitiator system. In addition, some new methods such as up/down-conversion luminescence, visible/infrared photocuring and two-photon curing are introduced. The advantages and disadvantages of each method are summarized to provide direction for future scientific research.
