近日,北京航空航天大学刘明杰团队研究了调节约束链弛豫的高能量耗散聚合物凝胶。该研究于2026年2月4日发表在《中国高分子科学杂志》上。
依赖玻璃化转变区显著内摩擦作用的阻尼聚合物虽能抑制振动与噪声,但其阻尼温域通常较窄,且存在严重的力学失稳问题。天然阻尼组织(如皮肤与软骨)通过黏性流体与三维弹性骨架的协同作用实现高效能耗散。
这种二元结构启发了通过受限分子链与主体网络的黏弹性协同机制设计高耗散凝胶的策略。研究组系统综述了仿生阻尼聚合物凝胶的最新研究进展,详细阐明了相关结构设计及其对应性能。研究组期待该综述能进一步推动阻尼聚合物的设计与应用探索。

Abstract: Damping polymers relying on significant internal friction in glass transition regions can suppress vibrations and noise; however, these materials generally exhibit a narrow damping breadth and severe mechanical instability. Natural damping tissues such as the skin and cartilage achieve high energy dissipation through the combination of viscous fluid and a 3D elastic skeleton. This binary structure inspired a high energy dissipation gel design strategy using synergistic viscoelastic scheme of confined chains and host network. Herein, we provide a comprehensive overview of recent advances in bio-inspired damping polymer gels. The structural designs and their corresponding performances are elucidated in this review. We anticipate that this review will motivate further exploration of design and applications of damping polymers.
