Functional phase change materials (PCMs) capable of reversibly storing and releasing tremendous thermal energy during the isothermal phase change process have recently received tremendous attention in interdisciplinary applications. The smart integration of PCMs with functional supporting materials enables multiple cutting-edge interdisciplinary applications, including optical, electrical, magnetic, acoustic, medical, mechanical, and catalytic disciplines etc. Herein, we systematically discuss thermal storage mechanism, thermal transfer mechanism, and energy conversion mechanism, and summarize the state-of-the-art advances in interdisciplinary applications of PCMs. In particular, the applications of PCMs in acoustic, mechanical, and catalytic disciplines are still in their infancy. Simultaneously, in-depth insights into the correlations between microscopic structures and thermophysical properties of composite PCMs are revealed. Finally, current challenges and future prospects are also highlighted according to the up-to-date interdisciplinary applications of PCMs. This review aims to arouse broad research interest in the interdisciplinary community and provide constructive references for exploring next generation advanced multifunctional PCMs for interdisciplinary applications, thereby facilitating their major breakthroughs in both fundamental researches and commercial applications.

“…Recently, versatile porous supporting materials for PCMs have taken a big step forward in terms of functional customization, mainly including silica, 13 graphite, 14,15 carbon nanotubes (CNTs), 16 graphene, 17 boron nitride, 18 metal–organic frameworks, 19 aerogels, 20 and MXenes 21 . Among them, many porous supporting materials themselves enable photo‐ and electrothermal conversion functions or can also realize the functions of photo‐, electro‐, and magnetothermal conversion by integrating photosensitizers, thermally conductive agents, electrically conductive agents, and magnetic response agents 22–30 . Generally, 2D supporting materials are advantageous over 1D and 3D supporting materials for the encapsulation of PCMs, especially graphene and MXenes, due to their more exposed absorption sites, broadband intense absorption capacity, high thermal, and electrical conductivity in‐plane 31–36 .…”

In response to global energy scarcity, frontiers in multifunctional composite phase change materials (PCMs) with photo‐/electro‐/magnetothermal triggers show great potential in multiple energy utilization. However, most available composite PCM candidates are inadequate for multiple energy storage applications simultaneously. Herein, a green synthetic route is proposed to develop bimetallic zeolitic imidazolate framework (ZIF)‐derived 1D–2D bridged array carbon‐based composite PCMs for simultaneous photo‐/electro‐/magnetothermal energy storage applications. As graphitization‐induced catalyst, Co nanoparticles greatly boost the formation of ZIF‐derived 1D–2D bridged array carbon framework with high graphitization and low interface electrical/thermal resistance. Benefiting from the broadband intense photon capture, fast photon/electron/phonon transport, and surface plasma resonance effect of Co nanoparticles, the resulting composite PCMs integrate advanced photo‐, electro‐, and magnetothermal storage functions. Furthermore, composite PCMs also exhibit long‐lasting shape stability, structural stability, thermal storage stability, and photo‐/electro‐/magnetothermal storage stability after undergoing multiple heating–cooling cycles. This study is promising to accelerate the major breakthroughs of advanced multifunctional carbon‐based composite PCMs toward multiple energy utilization.

“…Nowadays, scholars have attempted to encapsulate the solid–liquid PCMs into three-dimensional (3D) networks to acquire form stability. − The technique of impregnating liquid PCMs into the pre-synthesized porous 3D networks is always called a two-step impregnation method . With the phase transition process, the capillary force and interfacial tension of the porous 3D network adsorb the liquid PCM and prevent its leakage .…”

Solid–liquid phase change materials (PCMs) with large latent heat can efficiently weaken thermal peaks, thus alleviating the thermal discomfort of human beings caused by electronic devices. However, the leakage during the melting process and the low thermal conductivity severely limit their application in electronic thermal management. In this study, a flexible and leakage-proof sodium alginate-based phase change composite film (PCCF) was first fabricated via a facile and green synthesis method with the assistance of stainless steel meshes, and its synthetic size could be easily regulated via a mold. Multiwall carbon nanotubes (MWCNTs) were used to enhance the thermal conductivity of the PCCF. Through the leakage prevention tests, it can be found that the PCCF-0.7 (the mass fraction of polyethylene glycol (PEG) was 70%) exhibited leakage proof under an external force. The phase change enthalpy of the PCCF-0.7 reached 100.05 J/g, and the enthalpy retention rate reached 76%. The radial thermal conductivity of PCCF-0.7 (contains 8 wt % MWCNTs) was 3.52 W/(m·K), 3810% higher than that of pure PEG. The heat transfer experiment demonstrated that the PCCF could efficiently store thermal energy; the maximum temperature of the analog smartphone could be reduced by 5.3 °C. Hence, the prepared PCCF is suitable for providing thermal comfort to electronic devices, and it is sustainable and eco-friendly.
