摘要

光聚合是一种环保、无损、安全、无溶剂的方法。此外,它保证了低能耗。因此,光聚合被用于许多科学学科,包括牙科用于生产光固化牙科材料。本文研究了以樟脑醌(CQ)和甲酰阴离子碘盐为基料的新型光引发体系,用于引发丙烯酸酯单体双酚A -甲基丙烯酸甘油酯(BisGMA)和三乙二醇二甲基丙烯酸酯(TEGDMA)的光聚合。以樟醌(CQ)和4-(二甲氨基)苯甲酸乙酯(EDB)光引发体系为参考。

Novel Effective Photoinitiators for the Production of Dental Fillings
Photopolymerization is an environmentally-friendly, non-destructive, safe and solvent-free method. Moreover it guarantees low energy consumption. Therefore the photopolymerization is used in many scientific disciplines, including dentistry for production photocurable dental materials. In this work, the new photoinitiating systems based on camphoroquinone (CQ) and iodonium salts with tosyl anion for initiation of photopolymerization of the acrylates monomers bisphenol A - glycidyl methacrylate (BisGMA) and triethyleneglycol dimethacrylate (TEGDMA) was studied. As a reference, camphorquinone (CQ) and ethyl 4-(dimethylamino)benzoate (EDB) photoinitiating system was used.
