温度敏感型树枝状聚合物是智能材料的一个非常重要的分支,它不但具有温度刺激响应的特点,而且结合了树枝状聚合物高度支化、多官能度、低粘度等特点,在生物医用材料、智能催化剂、智能传感器、多功能材料等研究领域有着重要的研究价值和应用前景。该类聚合物的制备方法较为多样,在树枝状聚合物端基引入特定基团,或者调节分子骨架中亲水和疏水片段的比例均可以制备温敏树枝状聚合物。本文综述了不同结构温敏树枝状聚合物的制备方法、温敏机理及其在智能传感器、智能催化剂、多功能材料等方面的应用研究。
Temperature-sensitive dendritic polymer is a very important branch of smart materials. It not only has the characteristics of temperature-stimulating response, but also combines the characteristics of highly branched, multi-functional and low viscosity of dendritic polymer. In biomedical materials , Smart catalysts, smart sensors, multi-functional materials and other research areas have important research value and application prospects. Such polymers are prepared in a variety of ways, with the introduction of specific groups at the end of the dendritic polymer or the modulation of the ratio of hydrophilic and hydrophobic segments in the molecular backbone to the preparation of the temperature-responsive dendritic polymer. This review summarizes the preparation methods, thermo-sensitive mechanisms and their applications in smart sensors, smart catalysts and multi-functional materials.
