Recent Progresses in Synthesis of Cyclic Polymers in Large-scale and Some Functionalized Composites
聚合物通常含有不同组成与数目的端基,其物理化学性质与此密切相关.环状聚合物不含端基,展现出独特的物理化学性能,如更小的流体力学尺寸和延缓的降解速度,引起人们广泛关注.发展高效的合成方法,实现环状聚合物的可规模化制备及组分与微结构的精准调控是高分子科学的前沿研究方向.本文以动态单链纳米颗粒内环化方法可规模制备环状聚合物为例,展示其面临的关键问题.以小尺寸环状有机结构化合物为例,展示了其在若干复合材料中的典型特性.未来将更加聚焦发展高效合成方法,精准控制环状聚合物尺寸、组成及序列结构,为其规模制备和商业化及高性能复合材料的发展提供新范式.
Among various architectures of polymers,end-group-free rings have attracted growing interests due to their distinct physicochemical performances over the linear counterparts which are exemplified by reduced hydrodynamic size and slower degradation.It is key to develop facile methods to large-scale synthesis of polymer rings with tunable compositions and microstructures.Recent progresses in large-scale synthesis of polymer rings against single-chain dynamic nanoparticles,and the example applications in synchronous enhancing toughness and strength of polymer nanocomposites are summarized.Once there is the breakthrough in rational design and effective large-scale synthesis of polymer rings and their functional derivatives,a family of cyclic functional hybrids would be available,thus providing a new paradigm in developing polymer science and engineering.
