Synthesis of three-dimensional graphene aerogel encapsulated n-octadecane for enhancing phase-change behavior and thermal conductivity

Abstract

Novel 3D-GA composite PCMs were successfully prepared for enhancing the thermal conductivity, energy storage capacity and thermal repeatability of PCMs.

Investigating the effects of adding hybrid nanoparticles, graphene and boron nitride nanosheets, to octadecane on its thermal properties

“…Since there is no similar study, comparing the outcomes of the current work for the nanocomposite was difficult. The results of this study, as shown in Table 2, aligned well with those outlined in prior works, 10,[29][30][31][32][33] and the simulations conducted in this work could be appropriately validated.…”

Near-infrared absorbing 2D/3D ZnIn2S4/N-doped graphene photocatalyst for highly efficient CO2 capture and photocatalytic reduction

“…On the other hand, three-dimensional (3D) graphene nanostructures composed of 2D graphene sheets have been intensively studied in energy storage [33][34][35], environmental remediation [36][37][38], and gas sensing [39][40][41]. Compared with 2D graphene counterparts, 3D graphene nanostructures can hold interconnected networks with more surface areas and active sites in addition to hierarchical frameworks, which make them an ideal scaffold to inhibit the aggregation or stacking of subunits [42][43][44][45][46]. Further, doping heteroatoms like N into 3D graphene may significantly modify the electronic structure as well as benefit the intimate contact between graphene with dissimilar materials [47][48][49][50].…”

Synthesis and Characterization of Paraffin/Metal Organic Gel Derived Porous Carbon/Boron Nitride Composite Phase Change Materials for Thermal Energy Storage

“…Although the composite can exhibit shape‐stabilized performance, the thermal conductivity improvement as well as PCM loading capacity is still a challenge. Consequently, introducing PCM into high thermal conductive matrixes including metal oxides, graphene aerogel, carbon nanotube (CNT), expanded vermiculite, metal nanoparticles graphite foam, EG have been reported to improve the thermal conductivity of composite PCMs. For example, with increased functionalized multi‐walled carbon nanotubes content, the thermal conductivity of paraffin/f‐MWCNTs composite PCMs showed significant improvement up to 0.53 W/mK without leakage .…”
