“…Among all GO-PEG PCMs, the latent heat of PGO-CTAB was the highest and increased by 18.31% compared to that of PEG6000 (161.74 J/g), so PGO-CTAB was considered as the best thermal enhancement GO-modifier and the best candidate for the further preparation of biochar composite PCMs. PGO-CTAB has a better latent heat of phase change (77.27–106.5 J/g) compared to porous diatomaceous earth powder with adsorbed polyethylene glycol (PEG) PCMs [ 25 ].…”

In recent years, phase change materials (PCMs) have been widely used in waste heat utilization, buildings, and solar and wind energy, but with a huge limitation from the low thermal conductivity, photothermal conversion efficiency, and low latent heat. Organic PCMs are eyecatching because of its high latent heat storage capability and reliability, but they still suffer from a lack of photothermal conversion and sharp stability. Here, we prepared sharp-stable PCMs by establishing a carbon material frame system consisting of graphene oxide (GO) and biochar. In particular, surfactants (CTAB, KH-560 and KH-570) were employed to improve the dispersity of GO in PEG. The differential scanning calorimetry results shows that the latent heat of PEG modified by CTAB grafted GO (PGO-CTAB) was the highest (191.36 J/g) and increased by 18.31% compared to that of pure PEG (161.74 J/g). After encapsulation of PGO-CTAB in biochar, the obtained composite PCM with the amount of biochar and PGO-CTAB in weight ratio 4:6 (PGO-CTAB/CS6(6)) possesses relatively high latent heat 106.51 J/g with good leak resistance and thermal stability, and with obviously enhanced thermal conductivity (0.337 W/(m·K)) and photothermal conversion efficiency (77.43%), which were higher than that of PEG6000 (0.325 W/(m·K), 44.63%). The enhancement mechanism of heat transfer and photothermal conversion on the composite PCM is discussed.

“…[40][41][42][43] Energy storage reinforcement of formstable composite PCMs explicitly relies on the structure and properties of the ESI. [44][45][46][47] As a cutting-edge concept, aerogels, known as hyper-porous nanostructures, have been proposed as supporting scaffolds to confine PCMs. [48][49][50][51][52] Additionally, the properties of the aerogels used for encapsulation can be integrated into composite PCMs to create multifunctional thermal management systems.…”

“…[21] The way to overcome the low thermal conductivity is to introduce high-thermal-conductivity fillers like metal nanoparticles [22,23] and carbon nanofillers. [24,25] Due to the abundant types of carbon nanofillers and their remarkable thermal conductivity and low density, many studies have concentrated on the thermal conductivity enhancement effect of incorporating carbon nanofillers. Frequently adopted ones are carbon nanofibers (CNF), carbon nanotubes (CNT), graphene nanoplates (GNP), expanded graphite (EG), graphite, and graphite oxide (GO).…”

The form‐stabilized phase change materials (PCMs) comprised of lauric acid (LA), high‐density polyethylene (HDPE) and graphene nanoplates‐carbon nanofibers (GNP‐CNF) hybrid fillers were synthesized by melt blending method in this work, and the effects of GNP‐CNF mass ratio on thermal properties were investigated. The results from FT‐IR and XRD reveal that LA, HDPE, GNP and CNF were integrated with each other in a physical manner. The LA/HDPE/GNP‐CNF composites possess melting points very close to that of pure LA, with melting latent heats of 113.83–119.84 J/g. Thermal conductivity results indicate that the effect of GNP is better than that of CNF at the same content. The synergistic effect of hybrid carbon fillers can achieve higher thermal conductivity value compared to a single GNP or CNF. The synergistic thermal conductivity improvement mechanism is also analyzed. The sample SN2 (GNP: CNF is 1.7:0.3) exhibits the best thermal conductivity of 0.759 W/(m·K), with 2.73 times that of SN0. It also presents satisfactory thermal stability and reliability, allowing it to have promising applications in thermal energy storage.
