摘要
超支化聚合物由于具有高度支化的三维球状立体结构和众多的末端基团,显示出与相应线型分子截然不同的性质,如低黏度、良好的溶解性和大量可修饰的末端官能团等,具有广泛的应用前景,而且合成相对简单、成本低,因此成为近年来聚合物科学领域的研究热点.本文主要就超支化聚合物的结构、合成、性质和应用,从传统结构和含有大π共轭结构的新型超支化聚合物两个角度比较全面地总结了这一领域在基础理论和应用研究方面的发展概况和最新进展;着重介绍了超支化聚合物的结构、性质与其在新型功能材料如纳米材料、药物缓释剂、电致发光材料、传感材料等方面应用的内在关系,并进一步提出了该领域的研究前景及尚待解决的问题.
Hyperbranched polymers are a type of highly branched polymers with a multitude of end groups. Because of their highly branched three-dimensional and sphere-like molecular architecture, hyperbranched polymers have shown very different properties from those of their linear analogues, such as low viscosity, high solubility and a large number of terminal functional groups that can be modified. Hence, a great deal of attention has been focused on hyperbranched polymers due to their unique structure, broad application fields, relatively easy synthetic methods and low cost. This paper reviews the development and the most recent advance of hyperbranched polymers in structure （including traditional structure and novel rc conjugated structure）, synthetic methods, properties and applications, with an emphasis being laid on the intrinsic relationships between structure, properties and applications as novel functional materials, such as nano-materials, drug delivery agents, electroluminescent materials and sensory materials. Additionally, the perspectives and the problems should be solved in the future are provided.
