Abstract

Thermal energy storage (TES) technology has attracted much attention from various industrial fields owing to its high heat storage capacity and versatile energy conversion pathways. Among TES technologies, latent heat storage (LHTES) utilizing solid-liquid phase change materials (PCMs) demonstrates particular promise for practical engineering applications through its mild operation characteristics and minimized temperature fluctuations during energy exchange. Nevertheless, inherent limitations including leakage risks, structural deformation, and intrinsically low thermal conductivity continue to challenge PCM implementation. Recent advancements in materials engineering have pioneered an innovative solution through the development of phase change hydrogels (PCHs), which effectively encapsulate PCMs within three-dimensional polymer networks to create form-stable heat storage composites. Herein, we comprehensively review the synthesis methods, multifunctional applications, and enhancing mechanisms of the PCHs. This review reveals critical interdisciplinary synergies bridging thermal physics, materials science, and chemical engineering. By addressing current technical barriers and outlining future research trajectories, the review aims to stimulate interdisciplinary collaborations and developments.

固-液相变材料满足水凝胶：合成和多功能应用

热储能技术以其高储热能力和多用途的能量转换途径而受到各个工业领域的广泛关注。在TES技术中，利用固液相变材料（PCMs）的潜热储存（LHTES）由于其温和的操作特性和能量交换过程中最小的温度波动，在实际工程应用中表现出特别的前景。然而，包括泄漏风险、结构变形和固有的低导热性在内的固有局限性继续挑战着PCM的实施。材料工程的最新进展通过开发相变水凝胶（PCHs）开创了一种创新的解决方案，该解决方案有效地将pcm封装在三维聚合物网络中，以创建形状稳定的储热复合材料。本文就PCHs的合成方法、多功能应用及增强机制进行综述。这篇综述揭示了热物理、材料科学和化学工程之间关键的跨学科协同作用。通过解决当前的技术障碍和概述未来的研究轨迹，该综述旨在促进跨学科的合作和发展。
