“…Apart from commercial MF, PU foam is also utilized to encapsulate PCMs for preparing flexible composite PCMs. Flexible solar-absorbing composite PCMs were prepared by impregnating stearic acid (SA) into rGO-coated PU foam ( Chang et al., 2020 ). Inspired by the behavioral spreading and folding of buttery wings, this roll-to-roll charging strategy overcame the heat transfer limitation for fast solar-thermal energy harvesting within flexible composite PCMs.…”

“…However, an insightful understanding of flexible engineering of advanced PCMs is still insufficient. From the perspective of material science, herein, we systematically outline a comprehensive review of flexible PCMs based on different dimensional flexible additives, including 1D flexible additives, such as cellulose( Wei et al., 2019 ) and carbon nanotubes (CNTs) ( Wang et al., 2021a ); 2D flexible additives, such as graphene and their derivatives( Li et al., 2018 ), boron nitride (BN) ( Wang et al., 2020a ) ( Yang et al., 2018 )and MXene( Gong et al., 2021 ); and 3D flexible additives, such as EG( Wu et al., 2020c ), foam( Chang et al., 2020 ) and other 3D flexible materials 157 ( Figure 1 ). Moreover, we highlight fabrication techniques, flexibility evaluation strategies, advanced applications, current developments and further perspectives for flexible composite PCMs.…”

“…Generally, HTFs (e.g., metal oxide, and carbon materials) were widely used due to their excellent thermal conductivity and black color nature. [227][228][229][230] Considering the requirements for heat transfer fluids in the thermal management process, [226,231,232] the properties of PLs may meet this demand. For example, a previous study has indicated that hollow carbon PLs can be exploited as a promising platform for heat energy transfer.…”

Porous liquids (PLs), an emerging type of flowing liquid materials that combine the merits of porous solids and flowing liquids, have garnered immense attention since the concept of PLs was proposed in 2007. Meanwhile, PLs have witnessed growing success in versatile synthesis strategies and emerging applications, especially since 2017. Given the lack of a timely comprehensive review, developing a prompt summary with a comprehensive understanding is undoubtedly urgent. Thus, this critical review offers a comprehensive summary of the progress in fundamental chemistry, developmental history, synthetic strategies, and emerging applications of PLs. First, the fundamental chemistry and developmental history are reviewed. Then, the synthesis strategies of PLs are highlighted. Additionally, crosscutting studies of pure theoretical simulations are reviewed. Meanwhile, the daunting characterization issues of PLs are analyzed. Next, the state-of-the-art of PLs applications is reviewed in detail. In the end, perspectives regarding the remaining challenges and future directions for PLs are presented. It is speculated that this critical comprehensive review of PLs could inspire scientific communities who focus on the taskspecific materials for various applications, such as gas sorption, membrane separation, catalytic conversion, chiral separation, thermal management and electrolyte, and so on.

“…For example, Chang et al used rGO as a photothermal conversion medium, which enabled the photothermal conversion capacity of composite PCM up to 94.0%. 32 RHTC has a wider range of visible light absorption, and thus more thorough absorption of light, which can convert light energy into heat energy more effectively. It can make up for the disadvantage of poor photothermal conversion of BN and give the composite PCM excellent photothermal conversion ability.…”

Phase change materials (PCM) have broad application prospects in energy utilization and thermal management due to their high heat storage capacity. Current research focuses on solving the problems of easy leakage and slow heat transfer during the phase change of PCM. However, problems such as strong rigidity and weak light absorption also severely limit their practical applications. In this work, the RHTC-BN compound was prepared by sonicating carboxy-rich carbon (RHTC) and boron nitride (BN). The flexible (RHTC-BN)/MF was prepared by coating BN on melamine sponges (MF) skeleton using RHTC as a bridge. (RHTC-BN)/MF/PEG PCM was prepared by vacuum impregnation polyethylene glycol (PEG) into (RHTC-BN)/MF. The high porosity and low density of (RHTC-BN)/MF give (RHTC-BN)/MF/PEG PCM excellent leak-proof performance and high latent heat (151.4 J/g), and the optimal loading of PEG is 92.3 wt %. The bridging effect of RHTC drives the formation of a cross-interconnected 3D thermal conductivity network in (RHTC-BN)/MF, which endows (RHTC-BN)/MF/PEG PCM with high thermal conductivity (0.92 W m–1 K–1). Research proved that the flexibility of (RHTC-BN)/MF sponge and the phase change behavior of PEG does not just provide (RHTC-BN)/MF/PEG PCM with thermally driven shape memory (recovery speed of about 355 s) and self-adhesive function. Moreover, the photothermal conversion energy storage efficiency is as high as 91.5%. It has excellent potential in solar energy storage systems and provides a pathway for developing thermally responsive shape adaptive devices for energy storage applications.
