Abstract

In this study, a triple-shape memory polystyrene based polymer (SMPS) is synthesized, which mainly consists of styrene, vinyl compound, and cross-linking agent (bifunctional monomer). Benzoperoxide is used as the reaction initiator, the polymerization temperature is 75 oC, and the reaction time is 24 h. Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) results demonstrate that the crosslinked styrene based polymer possess two well-separated transition temperatures, which are subsequently used for the fixing/recovery of two temporary shapes. Furthermore, the versatile triple-shape memory functionality is demonstrated, and the result shows that the material has an excellent triple-shape memory effect. Based on the unique advantages, the SMPS material can be potentially used in sensors and actuators.
