“…In this research, both the Jeziorny method and the Mo method were successful in describing the nonisothermal crystallization behavior of the EVA/NBR TPV, while the Ozawa method failed to describe the nonisothermal crystallization behavior. This result is similar to the findings of our previous research, 28,37 the research further proved the identical perspective.…”

Thermoplastic vulcanizate (TPV) made from the ethylene-vinyl acetate copolymer (EVA)/nitrile rubber (NBR) blend was fabricated using the dynamic vulcanization method. Differential scanning calorimetry (DSC) was utilized to analyze the nonisothermal crystallization kinetics of both pure EVA and EVA/NBR TPV. The nonisothermal crystallization mechanism was evaluated using the Avrami method modified by Jeziorny, the Ozawa method and the Mo method. The results demonstrate that the nonisothermal crystallization of both pure EVA and EVA/NBR TPV can be adequately described by the Avrami method modified by Jeziorny and the Mo method, while the Ozawa method is not applicable. By elevating the cooling rate, there was a reduction in the crystallization temperature and t1/2 for both pure EVA and EVA/NBR TPV, while the degree of crystallization increased. At the same cooling rate, the crystallization temperature of the EVA/NBR TPV was found to be higher than that of the pure EVA, suggesting that the presence of NBR facilitated the nucleation of the EVA matrix within the EVA/NBR TPV. Moreover, a steric hindrance effect existed in the NBR phase of EVA/NBR TPV at the same cooling rate, resulting in a larger t1/2 compared to that of the pure EVA, indicating hindered crystal growth.

Triple shape memory materials currently have a wide range of applications in aerospace and healthcare, however, the lack of their mechanical properties limits their wider application. In order to overcome the problem of low mechanical properties of the triple shape memory composites, in this study, organoclay (OC), which is low-cost and has an intercalation-type structure, was introduced as a reinforcing phase in a trans-isoprene (TPI) with regular molecular chains and a low-crosslinking low-density polyethylene (LDPE) matrix. TPI/LDPE/OC shape memory composites (SMP) were prepared by melt blending and vulcanized by dynamic vulcanization technique. Since different OC contents have different effects on the properties of the composites, it is particularly important to select the appropriate OC content. A series of experiments were conducted to reveal the effect of OC content on the mechanical and shape memory properties of TPI/LDPE/OC composites. The results show that OC can form a stable and homogeneous intercalation structure in the composites when the OC incorporation amount is 2 phr, and the mechanical properties and triple shape memory properties of the composites are optimized. This study demonstrates that OC can improve the crystallinity and cross-linking of TPI/LDPE composites, thus providing potential value for the study of multiple shape memory material applications.
