Abstract

In this work, we report the first hybrid nanosized photoinitiators with low cytotoxicity and migration by coupling of polyhedral oligomeric silsesquioxanes (POSS) to benzophenone derivatives. This new series of photoinitiators were fully characterized and showed many favorable properties such as uniform sizes, extremely low tendency to migrate, less effect on resin viscosity, enhanced thermal stability and mechanical strength, increased photoactivity, and significantly lower cell toxicity compared to their corresponding benzophenone molecules. The utility of these hybrid nanosized photoinitiators in 3D printing was demonstrated in printing of various 3D structures with high resolution and accuracy.
