力响应性聚合物的研究进展

The Research Progress of Stress-responsive Polymer

在众多响应性聚合物中(光、电、热等),力响应性聚合物是近十年来兴起的一个热点领域。力响应性聚合物是指聚合物受外界力作用时,能够相应的发生一系列化学或物理性质的变化。制备力响应聚合物的关键是利用这类力敏感的基团。至今,已制备的力色团有20余种,研究发现含力色团的聚合物具有变色、发光、催化、释放小分子等响应性,是一种很有潜力的智能材料。本文简要概述了力色团的种类、机械力,重点阐述了力响应性聚合物的应用,最后对力色团实际应用及未来发展趋势进行了展望。

Among the various stimuli-responsive polymers(e.g.light,voltage,heat,etc),mechanoresponsive polymers have raised hot fields during last decades.With the exogenous force drive,the mechanoresponsive polymers materials are able to induce a series of chemical and physical changes.And the most important of synthetic materials are to utilize the sensitivity small molecular.Till now,only 20 mechanophores have been successfully synthesized and it's a potentially intelligent material that their polymer has the responsiveness such as color change,luminescence,catalysis and release of small molecules,ect.In this review,the kinds of mechanophores and mechanical force are summarized.Then the aplication of mechanoresponsive polymers are discussed in detail.The actual application of mechanophores and future development trend are lastly outlined.
