In this paper, dual-response shape-memory polymers (SMPs) based on carboxylic styrene butadiene rubber (XSBR)/ferriferrous oxide (Fe3O4)/zinc dimethacrylate (ZDMA) were designed. Fe3O4 was incorporated to endow XSBR with a magnetic property and improve its glass transition temperature (Tg). ZDMA was employed as an in situ reinforcer and compatibilizer for Fe3O4 and XSBR, which further improved Tg of the SMPs by introducing ionic cross-linking points. With incorporation of 10 phr ZDMA, Tg increased to 28.3 °C, the shape fixation ratio of the SMP was ∼100% at room temperature, the shape recovery ratio was ∼100% in both a thermal field and an alternating magnetic field, and the tensile strength reached 30.26 MPa. The chemical and physical properties of the SMPs were characterized by curing tests, cross-link density measurements, scanning electron microscopy, differential scanning calorimetry, and tensile tests. Such dual-response SMPs exhibit potential applications in intelligent biomedical devices over a wide temperature range.

具有双响应的高强度XSBR / Fe 3 O 4 / ZDMA形状记忆复合材料的设计
本文设计了基于羧基丁苯橡胶（XSBR）/氧化亚铁（Fe 3 O 4）/二甲基丙烯酸锌（ZDMA）的双响应形状记忆聚合物（SMP）。掺入Fe 3 O 4以赋予XSBR磁性，并改善其玻璃化转变温度（T g）。ZDMA被用作Fe 3 O 4和XSBR的原位增强剂和增容剂，通过引入离子交联点进一步改善了SMP的T g。结合10 phr ZDMA，T g当温度升至28.3°C时，SMP在室温下的形状固定率为〜100％，在热场和交变磁场中的形状恢复率均为〜100％，抗拉强度达到30.26 MPa。通过固化测试，交联密度测量，扫描电子显微镜，差示扫描量热法和拉伸测试对SMP的化学和物理性质进行了表征。这种双响应SMP在很宽的温度范围内显示出在智能生物医学设备中的潜在应用。
