摘要
In the past two decades,dynamic covalent chemistry has been greatly developed,which is mainly reflected in two aspects:1.new dynamic covalent bonds(DCBs)are continuously discovered;2.various DCBs have been introduced into polymer materials for different functions.These functional polymer materials have brought new opportunities for sustainable development.In this review,we provide an overview of various functions endowed by DCBs in polymer materials,including self-healing,chemical recycling,and shape controlling.Particularly,we pay much attention to the three-dimensional(3D)shape reconfiguration/programming,surface patterning,and reversible actuation.In addition,we also give the current issues,challenges,and opportunities on DCBs-containing materials and point out its developing directions in the future.
在过去的二十年中,动态共价化学得到了极大的发展.这主要体现在两个方面:(1)新的动态共价键源源不断地被发现;(2)各种各样的动态共价键被引入到高分子材料中并用于实现某些特殊的功能.这些功能高分子材料的开发和应用为人类社会的可持续发展注入了新的活力和生机.本文主要综述了由动态共价键所赋予高分子材料的一系列新功能,包括自修复、循环利用和形状控制.在这些新功能中,我们尤其关注由动态共价键引起的重塑形、三维形状编程、表面图案化和可逆致动等新功能.除了这些动态功能外,我们还讨论了目前动态共价键在功能高分子材料发展过程中所遇到的问题、挑战和机遇,并展望了动态功能高分子材料在未来的发展方向和应用前景.
