摘　　要：含能聚醚黏合剂作为推进剂的骨架和基体,是促进推进剂的能量水平、力学性能、加工性能等不断改善的基础。然而,聚醚中的极性含能基团阻碍了分子链的运动,降低了高分子链的柔顺性,导致力学性能下降,制约了高能固体推进剂的发展。对含能聚醚进行共聚改性,引入柔性链段提高柔顺性是获得结构多样、性能可调聚醚的有效方法。本研究介绍了近年来含能聚醚引入不同类型的柔性链段,从主链柔性链段、侧链柔性链段两个角度展开综述,阐释其对含能聚醚黏合剂力学性能和加工性能的影响,并对含能聚醚黏合剂的柔性链结构设计研究进行了展望,为设计开发新型含能黏合剂提供方向。Energetic polyether binders,as the backbone and matrix of propellants,are the basis to improve the energy levels,mechanical properties,and processing properties of propellants.However,the polar energetic groups in polyethers hinder the movement of molecular chains and reduce the flexibility of polymer chains,leading to a decrease in mechanical properties and restricting the development of energetic solid propellants.Copolymerization modification of energetic polyethers and introduction of flexible structural units to improve flexibility are effective methods to obtain polyethers with diverse structures and adjustable properties.This paper summarizes different types of flexible chain segments introduced into energetic polyethers in recent years,and discusses from the perspectives of main‑chain flexible chain segments and side‑chain flexible chain segments to explain their effects on the mechanical properties and processing performance of energetic polyether binders.Future design of the flexible chain structure of energetic polyether binders is also discussed,which will provide a direction for the design and development of new types of energetic binders.
