In this work, we fabricated porphyrin-loaded shape memory polymer (SMP) film by cross-linking micellar particles prepared by co-assembly of porphyrin compounds and amphiphilic macromolecules formulated by copolymerization of 2-butoxy ethanol (BCS), methyl methacrylate (MMA), butyl acrylate (BA) acrylic acid (AA), and diacetone acrylamide (DAAM). The experimental results revealed that this film was able to respond to the red light in terms of photothermal effect enabled by the porphyrin filler. The photothermal-triggered shape memory behaviors of the film were further examined in detail. It was noteworthy that this material was expected to have potential applications in the biomedical field due to the excellent biocompatibility of the porphyrin filler and the red-light source, which was optimal and safe enough for biomedical treatment.
在本工作中，我们通过交联胶束颗粒制备了负载卟啉的形状记忆聚合物（SMP）薄膜，所述胶束颗粒由卟啉化合物与两亲性大分子共组装而成，两亲性大分子由2-丁氧基乙醇（BCS）、甲基丙烯酸甲酯（MMA）、丙烯酸丁酯（BA）、丙烯酸（AA）和双丙酮丙烯酰胺（DAAM）共聚而成。实验结果表明，该薄膜能够通过卟啉填料实现的光热效应响应红光。进一步详细研究了该薄膜的光热触发形状记忆行为。值得注意的是，由于卟啉填料和红光光源具有优异的生物相容性，对于生物医学治疗而言足够优化且安全，因此该材料有望在生物医学领域具有潜在应用。
