“…In addition, HNTs can provide the system with excellent thermal stability. Gao et al [140] further demonstrated that organic montmorillonite (OMT) minerals can be used as cross-linked nonhomogeneous nucleating agents to improve the temperature control, crystallization ability, and thermal stability of solid-solid phase change polyurethane materials. Zhao et al [141] successfully applied PEG/polyamide 6 (PA6) to the development of nanofiber energy storage materials by coaxial electrostatic spinning.…”

As the core material of thermal energy storage technology, phase change materials (PCM) suffer serious leakage problems and slow thermal conductivity in applications. Nanoclay with relatively high specific surface area, high thermal conductivity, and abundant pore structure can successfully compensate for the defects in PCM. However, the ability of nanoclay without further modification to encapsulate the PCM for the preparation of form stable phase change materials (FSPCM) and accelerate their heat transfer is limited. Nanoclay is classified into 1D, 2D, and 3D minerals based on their microscopic morphology. In this review, the specific surface and pore structure of three types of nanoclay and their thermal performance after loading with PCM are summarized and compared. Then, different mineral modification treatments, such as pretreatment, surface modification, structural modulation, and functional assembly, are summarized to investigate the enhancement of thermal performance in nanoclay‐based FSPCM. This review also summarizes the state‐of‐the‐art research progress of emerging nanoclay material‐based FSPCM. Finally, a summary of the traditional applications of mineral‐based FSPCM and an outlook on new applications are presented. This paper will help researchers to better understand the recent developments, performance enhancement strategies of nanoclay‐based FSPCM and to identify potential future research efforts.

“…In addition, if the phase transition of the PCM in question is solid to liquid, it will probably be necessary to use a material that acts as a capsule or support for the PMC to prevent its leakage, which could even hurt the mechanical properties of the pavement [ 12 , 13 ]. In this case, the literature fundamentally presents two possibilities: (i) encapsulation (by melamine–formaldehyde resin [ 14 ], acrylic-based polymers [ 15 ], and CaCO 3 [ 16 ], among others) or (ii) impregnation using porous materials (silica fume [ 17 ], diatomite [ 18 ], expanded graphite, and others [ 19 ]) or crystalline/lamellar materials (expanded graphite [ 20 ], reduced graphene oxide [ 21 ], and montmorillonite [ 22 ] ( Figure 1 ).…”

This research presents a dual-pronged bibliometric and systematic review of the integration of phase change materials (PCMs) in asphalt pavements to counteract the urban heat island (UHI) effect. The bibliometric approach discerns the evolution of PCM-inclusion asphalt research, highlighting a marked rise in the number of publications between 2019 and 2022. Notably, Chang’an University in China has emerged as a leading contributor. The systematic review addresses key questions like optimal PCM types for UHI effect mitigation, strategies for PCM leakage prevention in asphalt, and effects on mechanical properties. The findings identify polyethylene glycols (PEGs), especially PEG2000 and PEG4000, as prevailing PCMs due to their wide phase-change temperature range and significant enthalpy during phase transitions. While including PCMs can modify asphalt’s mechanical attributes, such mixtures typically stay within performance norms. This review emphasises the potential of PCMs in urban heat management and the need for further research to achieve optimal thermal and mechanical balance.

“…[23,24] This is mainly achieved by chemically functionalizing or cross-linking PCM with polymer. [15,[24][25][26][27] However, the solid-solid PCM still suffers from the low 𝜅. The recyclability is also limited since the cross-linked PCM is not healable due to irreversible chemical bonds.…”

Phase-change materials (PCMs) have received considerable attention to take advantage of both pad-type and grease-type thermal interface materials (TIMs). However, the critical drawbacks of leaking, non-recyclability, and low thermal conductivity (𝜿) hinder industrial applications of PCM TIMs. Here, leakage-free healable PCM TIMs with extraordinarily high 𝜿 and low total thermal resistance (R t ) are reported. The matrix material (OP) is synthesized by covalently functionalizing octadecanol PCM with polyethylene-co-methyl acrylate-co-glycidyl methacrylate polymer through the nucleophilic epoxy ring opening reaction. The OP changes from semicrystalline to amorphous above the phase-transition temperature, preventing leaking. The hydrogen-bondforming functional groups in OP enable nearly perfect healing efficiencies in tensile strength (99.7%), 𝜿 (97.0%), and R t (97.4%). Elaborately designed thermally conductive fillers, silver flakes and multiwalled carbon nanotubes decorated with silver nanoparticles (nAgMWNTs), are additionally introduced in the OP matrix (OP-Ag-nAgMWNT). The nAgMWNTs bridge silver-flake islands, resulting in extraordinarily high 𝜿 (43.4 W m −1 K −1 ) and low R t (30.5 mm 2 K W −1 ) compared with PCM TIMs in the literature. Excellent heat dissipation and recycling demonstration of the OP-Ag-nAgMWNT is also carried out using a computer graphic processing unit. The OP-Ag-nAgMWNT is a promising future TIM for thermal management of mechanical and electrical devices.
