Catalyst Control of Interfacial Welding Mechanical Properties of Vitrimers
文献摘要：
Interfacial welding of thermosetting polymers has been a challenge,but vitrimers with dynamic covalent networks open numerous opportunities for welding and adhesion of these materials.In this work,we performed interfacial welding between epoxy-based vitrimers and an epoxy vitrimer and a thermoplastic polyurethane(TPU).Catalyst-controlled interfacial mechanical properties for both the vitrimer/vitrimer and vitrimer/TPU are observed,that is,the more efficient the catalyst for the transesterification reactions,the larger the interfacial fracture energy is,and the better the welding strength will be.The interfacial mechanical properties are also found to be independent of the original mechanical properties of the vitrimers.Even for a vitrimer with poor mechanical properties,both the welded vitrimer/vitrimer and vitrimer/TPU exhibit larger interfacial fracture energy than the one with better mechanical properties as long as the former uses more efficient catalyst.
