化学自振荡反应驱动的智能高分子材料常被称为自振荡高分子材料(self-oscillating polymer materials,SOPMs),其中以Belousov-Zhabotinsky(BZ)反应驱动的SOPMs研究最为深入,为高分子材料领域的一大研究热点。与传统智能高分子材料不同,SOPMs体系具有高度的自调节性,即可以不需要外界“开-关”转换的刺激就能自动、可逆、周期性地发生状态转变。本文结合SOPMs的最新研究结果,介绍该类材料在新型拓扑结构设计和仿生功能研究两个方面的新思想和新方法。在拓扑结构设计方面,主要介绍梳形自振荡高分子凝胶、“聚轮烷”互锁自振荡高分子凝胶、多级结构自振荡高分子凝胶、超级交联自振荡高分子凝胶、支化自振荡高分子、自振荡高分子刷以及嵌段自振荡高分子材料。在仿生功能研究方面,主要阐述自振荡高分子囊泡、人工细胞、自主肠状运动、趋光避光运动。最后,对SOPMs今后的发展作了展望。
Self-oscillating polymer materials (SOPMs), which are driven by chemical self-oscillation reaction, are often called self-oscillating polymer materials. Among them, SOPMs driven by Belousov-Zhabotinsky (BZ) reaction are the most intensively studied. A major research hot spot. Different from the traditional smart polymer materials, SOPMs system has a high degree of self-regulation, that is, it can automatically, reversibly and periodically change state without the stimulus of “on-off” conversion. Based on the latest research results of SOPMs, this paper introduces the new ideas and new methods of this kind of materials in the aspects of new topological structure design and bionic function research. In topology design, we mainly introduce comb-like self-oscillating polymer gel, polyrotaxane interlocking self-oscillating polymer gel, multistage self-oscillating polymer gel, supercrosslinked self-oscillating polymer Gel, self-oscillating polymer, self-oscillating polymer brush and block self-oscillating polymer material. In the research of bionic function, we mainly describe self-oscillating polymer vesicles, artificial cells, independent gut motility, light and dark movement. Finally, the future development of SOPMs is prospected.
