摘要
二氧化碳(CO2)刺激响应性聚合物是近年来新发展的一类智能型聚合物。它是指在向聚合物体系内部引入或排出CO2气体后,聚合物的结构与性质能够发生可逆变化的新型大分子。由于在调控的过程中只向体系内部引入了CO2气体刺激源,使得在多次可逆的循环过程中避免了传统刺激方式(酸碱、氧化还原剂、离子、酶等)的杂质积累,因此具有极高的应用潜力和价值。利用聚合物响应CO2的特性,可以在多个方面对其进行开发和应用。文中对近年来各种新型CO2刺激响应性聚合物的合成、组装及应用进行总结与归纳,并对这类智能大分子的应用前景和发展方向进行了合理展望。
CO2-responsive polymers are a class of novel and smart macromolecules developed in recent years. They can be defined as specific polymer systems that can respond to CO2 stimulus and result in reversible structural changes. Since one only introduces CO2 gas into the polymer system, it can effectively avoid the byproduct accumulation of traditional stimulation modes such as acids, bases, redox agents, ions, and enzymes. Utilizing CO2-responsiveness these polymers can be applied in a broad spectrum of fields. This review aims to summarize the synthesis, characterization, self-assembly, and applications of these new CO2-responsive polymer systems, and propose the potential perspectives of these smart macromolecules.
