聚酰亚胺基相变复合材料的研究进展OA

Efficient thermal management represents a ubiquitous technical challenge across energy storage,aerospace,construction,and smart tex-tile applications.Phase change materials(PCMs),renowned for their high latent heat capacity,have emerged as focal research subjects in ther-mal management.However,leakage issues inherent to solid-liquid phase transitions severely impede their practical deployment.Polyimide(PI)-based shape-stabilized phase change composites,distinguished by exceptional thermal stability,mechanical robustness,and chemical inert-ness,offer a viable solution to this bottleneck.This review systematically summarizes the physicochemical properties of PCMs commonly employed in PI matrices,delineates advances in fabrication methodologies encompassing physical encapsulation and chemical grafting strategies,and pros-pects the application potential of this material architecture in thermal management domains.
