Phase change materials store and release heat energy in the process of phase change, so as to realize the effective recovery and utilization of heat energy. In this work, ultra-high molecular weight polyethylene (UHMWPE)@carbon nanotubes (CNT) 3D porous matrix were fabricated by rotary sintering. By vacuum adsorbing paraffin wax (PW) into UHMWPE@CNT porous matrix, composite phase change materials (CPCM) with excellent shape stability and mechanical properties were obtained. In addition, thermal gravimetric analysis (TG) results showed that the thermal stability of PW in CPCM was significantly improved. Moreover, the highest thermal conductivity of CPCM was 0.31 W m À1 K À1 at a relatively low content of CNT, which was 1.71 times that of CPCM without CNT. CNT was uniformly dispersed in the porous matrix of UHMWPE to enhance the thermal properties of CPCM. Especially when the CNT content was 1.5%, the thermal storage performance and photothermal conversion efficiency of CPCM were effectively improved. Therefore, the CPCM prepared by this method with excellent combination property, had great application prospect in energy storage.

“…The best solution is to prepare composite PCMs by packaging PCMs into supporting materials ( Chen et al., 2020a ; Lin et al., 2018b ; Qureshi et al., 2018 ). To date, the most popular is carbon supporting materials, especially graphene and carbon nanotubes (CNTs) materials ( Aftab et al., 2019 ; Cao et al., 2019 ; Hu et al., 2020 ; Qian et al., 2018 ; Shin et al., 2016 ; Song et al, 2019 ; Tang et al, 2019 ; Wang et al., 2019b ; Wu et al, 2019 ; Xue et al., 2019 ; Zhang et al., 2019a , 2019b , 2019d ; Zhang and Liu, 2019 ).

Summary Efficient thermal energy harvesting using phase change materials (PCMs) has great potential for thermal energy storage and thermal management applications. Benefiting from these merits of pore structure diversity, convenient controllability, and excellent thermophysical stability, SiO 2 -based composite PCMs have comparatively shown more promising prospect. In this regard, the microstructure-thermal property correlation of SiO 2 -based composite PCMs is still unclear despite the significant achievements in structural design. To enrich the fundamental understanding on the correlations between the microstructure and the thermal properties, we systematically summarize the state-of-the-art advances in SiO 2 -based composite PCMs for tuning thermal energy storage from the perspective of tailoring chemistry strategies. In this review, the tailoring chemistry influences of surface functional groups, pore sizes, dopants, single shell, and hybrid shells on the thermal properties of SiO 2 -based composite PCMs are systematically summarized and discussed. This review aims to provide in-depth insights into the correlation between structural designs and thermal properties, thus showing better guides on the tailor-made construction of high-performance SiO 2 -based composite PCMs. Finally, the current challenges and future recommendations for the tailoring chemistry are also highlighted.

The highly efficient utilization of solar energy is urgent to deal with the energy crisis and environmental pollution causing by the petroleum energy, in which the strategy of photothermal conversion energy-storage materials via the photothermal conversion and phasechange process attracts much attention. [1] However, the no thermal effect for the 40% of the solar radiation energy during the photothermal conversion process and the leakage of phase-change materials (PCMs) during the solid-liquid transition, which greatly limited its wide application. [2] Generally, there are three kinds of shaped photothermal conversion PCMs, including dye-, metal-(metal oxide), and carbon-materials-shaped photothermal conversion PCMs. [3] The dye takes the advantages of strong selective absorption characteristics for the 40% of the solar radiation energy, good compatibility, and reactivity, showing broad application prospects in the fields of color temperature regulating fibers and textiles. [4] The metal and metal oxide are also applicated in the shaped photothermal conversion PCMs attributing to its low price and high-efficient light heat conversion capability. Moreover, the carbon materials, especially the nano-carbon materials including carbon nanotube (CNT), graphene, graphite, carbon fiber, etc., are often used to prepare photothermal conversion materials because of their strong light absorption, good physical performance, and excellent thermal conductivity. [5] Paraffin is widely applicated in the field of via solid-liquid phase transition at low temperature attributing to the high latent heat and excellent chemical stability. [6] However, its application was limited by the low thermal conductivity and leakage during the solid-liquid phase-transition process for the shaped photothermal conversion PCMs. [7] To solve the aforementioned problems, paraffin wax was usually encapsulated by or mixed with high thermal conductivity materials including metal, [8] graphite, [9] graphene, [10] CNT, [11] transition metal nitride, [12] etc. In particular, the composite PCM based on 3D skeleton has been widely studied because of its excellent leakage resistance and stable molding structure. Including the construction of 3D carbon-based aerogels [13] and magnetic metal foam frames, [14] which realizes efficient light/heat energy conversion and storage. Moreover, the carbon-based aerogels or foams were developed as the shaped structure to store the PCMs with excellent thermal conductivity and 3D porous structure. It should be noted that the graphene foam prepared via a simple method not only preventing the leakage of PCMs, but also improving the
