چکیده انگلیسی
A bio-based thermoplastic vulcanizate (TPV) composed of polylactide (PLA) and epoxidized natural rubber (ENR) was fabricated through dicumyl peroxide-induced dynamic vulcanization. It was found that the crosslinked ENR phase had a specific continuous structure, hence forming a bi-continuous structure in the TPV. We designed cyclic stress-strain, stress-soften and stress-relaxation tests and SEM observation to reveal the relationship between the PLA continuous phase and crosslinked ENR continuous phase. It was found that the PLA phase generated crazes to adapt the elongation of the ENR continuous phase during stretching. At the same time, the enhanced interface between PLA and ENR kept the stress transferring between the two phases. The ENR with more epoxy groups showed better compatibility with PLA, which resulted in better mechanical properties.
