“…The thermal conductivity of the as‐prepared composite was effectively enhanced up to 10.86 W m −1 K −1 , which is 43 times of pure PU. Similarly, other highly conductive phase change composites were designed by our group by infiltrating PU into the pores of CNT sponge . Due to the directional alignment of CNTs in polymer matrix, the thermal conductivities were anisotropic capable of reaching 2.4 W m −1 K −1 along the axial direction.…”

“…In the reverse process, an almost equal amount of energy was released through lattice coupling, which was transferred to PCM for latent heat storage. Considering the efficient photonic energy harvesting performance of CNTs, the anisotropic phase change composite, constituting a CNT sponge and polyurethane based solid–solid PCM, was recently fabricated by our group (Figure b) . The developed composites could also be driven by an electric means in order to remove the intermittency drawback of solar radiations.…”

Thermal energy storage technologies based on phase‐change materials (PCMs) have received tremendous attention in recent years. These materials are capable of reversibly storing large amounts of thermal energy during the isothermal phase transition and offer enormous potential in the development of state‐of‐the‐art renewable energy infrastructure. Thermal conductivity plays a vital role in regulating the thermal charging and discharging rate of PCMs and improving the heat‐utilization efficiency. The strategies for tuning the thermal conductivity of PCMs and their potential energy applications, such as thermal energy harvesting and storage, thermal management of batteries, thermal diodes, and other forms of energy utilization, are summarized systematically. Furthermore, a research perspective is given to highlight emerging research directions of engineering advanced functional PCMs for energy applications.

“…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 ). Undoubtedly, highly thermally conductive carbon materials can accelerate thermal transfer and boost the charging/discharging rates of composite PCMs.…”

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.

“…In this regard, macro-size container, microencapsulation or formstable composition is the alternative method to hold PCMs in position. [11][12][13][14][15][16][17] PCMs can be stored in macro-sized balls, tubes or plates. [18][19] Zhou et al tested the thermal performance of PCM bags in a radiant floor heating system in the basement.…”

Phase change material (PCM) can store heat at a constant temperature, which is beneficial to reduce building energy consumption. Herein, we fabricated a PCM board that can store 98-102 J/g heat at 26 °C. The PCM boards were paved as the floor in the real-scale office to reduce power for temperature regulation, which led to the reduced energy consumption of 18.8% and 19.7% in winter and summer, respectively. A numerical model is validated by experimental data to evaluate longterm performance. The experiment and simulation results both demonstrate the high-performance PCM floor for effective reduction in electricity consumption of heating and cooling.
