Graphene oxide-epoxy composites: Initiated by thermal latent catalysts |
| 초록 |
Curing of epoxy by homopolymerization provide advantages and broadens the field of application of these polymeric materials. 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 increment of filler contents |
