摘要
相变蓄热材料(PCM)可以通过相变吸收/释放大量热量而保持温度恒定不变,广泛应用于建筑节能、余热回收、冷链输运、太阳能-热能转换/储存和电池热管理等领域。然而,固-液PCM蓄热饱和后往往面临泄漏/形貌坍塌等稳定性问题。精细化设计/合成高吸附性功能高分子材料作为骨架包覆/封装PCM,或者将相变分子束缚在高分子骨架上获得可蓄热的相变功能高分子,是在兼顾储热密度条件下解决PCM稳定性问题的有效途径。本文以功能高分子材料为主题,围绕固-液PCM的功能高分子骨架、固-固相变功能高分子及其应用等3方面,综述了功能高分子在PCM中的应用研究进展,为PCM相关功能高分子材料的设计、制备提供一定的借鉴和参考。
Phase change thermal storage materials(PCMs)can store/release a large amount of heat through phase transition while keeping the temperature within a constant range,so they are widely used in building energy conservation,waste heat recovery,cold-chain transportation,solar-thermal energy conversion/storage,battery thermal management,and other fields.However,conventional solid-liquid PCMs confront severe problems of leakage and shape collapse after the saturation of heat storage.The most promising ways to solve these stability problems of PCMs while guaranteeing adequate thermal storage density are to elaborately design/synthesize high adsorptive functional polymer materials as the skeletons to encapsulate PCMs or constrain phase change molecules into polymer backbones to obtain phase-changeable functional polymers.This review summarizes the application research progress of functional polymers in PCMs,taking functional polymer materials as the theme and focusing on the three aspects of functional polymer frameworks of solid-liquid PCMs,solid-solid phase change functional polymers,and their application.This article is expected to provide significant references to the design and preparation of PCM-related functional polymer materials.
