| Abstract |
Curing of epoxy by homopolymerization provide advantages and broadens the field of application of these polymeric materials. Cationic initiators, which remain inactive under normal environmental conditions and became active by external stimulations such as heating and photoirradiation, had been synthesized and their importance has been recognized in organic and polymer synthesis. An optimization of thermal latent cationic curing of epoxy to fabricate GO/epoxy composites with enhanced mechanical and thermal properties were carried out. Commercially available diglycidyl ether of bisphenol A (DGEBA) was used as base resin and the thermally latent catalyst, N-benzylepyrizinium hexafluoroantimonate (N-BPH) was synthesized by using the reported method. The cationic system shows excellent latent curing which was not affected by adding filler. The cure kinetics was determined by DSC measurements. An improve in the thermal and mechanical properties of composites was observed by the increment of filler contents. |
