Polyurethane (PU) foam is widely used as a thermal insulating material but it does not possess thermal energy storage and thermal regulation properties. In the present work, the phase change material stearic acid (SA) is microencapsulated with melamine-formaldehyde resin and then introduced into PU prepolymer to fabricate composite foams. In this way, the phase change properties of SA are successfully infused into the PU foams, leading to improved heat storage and thermal regulation ability. The phase change enthalpy of composite PU foams can be facilely tailored from 3.45 to 14.59 J g −1 by changing the loading fraction of microcapsules, allowing an adjustable thermal energy storage and thermal regulation capacity. The composite PU foams exhibit good thermal reliability after 100 cycles of thermal testing. Morphology observation confirms strut rupture and broken cells as well as the distribution of the incorporated microcapsules inside the cell struts. It is found that the added microcapsules have a small influence on the foam density and thermal conductivity. Finally, the microcapsules present a marked effect on the mechanical properties, with an increased elastic modulus from 3.52 to 4.21 MPa and decreased compression strength from 0.29 to 0.13 MPa. We believe that our efforts on the design and development of composite PU foams with thermal energy storage and thermal regulation properties will contribute to broaden the application scope of PU foams.

Latent heat thermal energy storage (LHTES) uses phase change materials (PCMs) to store and release heat, and can effectively address the mismatch between energy supply and demand. However, it suffers from low thermal conductivity and the leakage problem. One of the solutions is integrating porous supports and PCMs to fabricate shape-stabilized phase change materials (ss-PCMs). The phase change heat transfer in porous ss-PCMs is of fundamental importance for determining thermalfluidic behaviours and evaluating LHTES system performance. This paper reviews the Highlights: 1. The recent advances in experimental and numerical investigations on phase change heat transfer in porous ss-PCMs are reviewed. 2. Paraffin and metal foams are the mostly used PCM and porous support respectively in the experimental studies. 3. Compared to REV-scale simulation, the pore-scale simulation can provide extra flow and heat transfer characteristics in pores. 4. There exists a research gap between phase change heat transfer and material preparation.

“…The best solution is to prepare composite PCMs by packaging PCMs into supporting materials. Currently, the two most popular packaging strategies are porous package (shape-stabilized PCMs) ( Grosu et al., 2020 ; Huang et al., 2019 ; Lu et al., 2019 ; Shen et al., 2019 ; Zhang et al., 2020b ) and core-shell package (micro/nano-encapsulated PCMs) ( Alehosseini and Jafari, 2019 ; Erdem and Gürbüz, 2019 ; Kakar et al., 2019 ; Xia et al., 2020 ), as shown in Figure 3 . In the composite PCMs, PCMs are working substances for thermal energy storage and supporting materials are employed to restrict the flow of liquid 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.
