Description

General description

Camphorquinone (CQ) absorbs UV radiation in the region of 200-300nm due to the Π−Π^* transition and visible light (400-500nm) due to the n, Π* transition of the α-dicarbonyl chromophore.

Application

CQ-amines are used as a photo initiators for free radical polymerization. CQ was used as an initiator in the preparation of silver nanoparticle/silica/ polymer nanocomposites. Photopolymerization kinetics of dimethacrylates were studied using the CQ/amine initiator system.

The Progress in Development of Dental Restorative Materials

With dentists placing nearly 100 million dental fillings into patients′ teeth annually in the U.S. alone, polymeric composite restoratives account for a very large share of the biomaterials market.

Quantum yield of conversion of the photoinitiator camphorquinone.

The primary absorber in dental resins is the photoinitiator, which starts the photo polymerization process. We studied the quantum yield of conversion of camphorquinone (CQ), a blue light photoinitiator, in dental resin composites using a LED lamp (3M FreeLight) and

Journal of dental research, dental clinics, dental prospects, 6(4), 131-137 (2013-01-02)

Effect of surface treatments on repair bond strength of aged composite resins might be different due to their dissimilar fillers. The aim was to evaluate the effect of different surface treatments on repair micro-shear bond strength (µSBS) of silica- (Spectrum
