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

“…Likewise, Xu and Li found improved thermal conductivity up to 42.45 % with the addition of MWCNT to paraffin/diatomite composite PCMs. At the same time, boron nitride (BN) has received a tremendous attention on improving the thermal properties of composite materials owing to its special natures in electronic devices, low cost, easy and green composite preparation steps , . Although much attention has been given for preparing thermosetting polymeric composites, BN has also been used to prepare shape stabilized PCMs and enhance the thermal conductivity of pure PCMs.…”

“…In addition, it can be employed with other supporting materials via hybrid network structure for synergistic enhancement of PCM heat transfer performance. Yang et al, introduced graphene oxide/BN hybrid matrixes into pure PCM to enhance the thermal conductivity, shape‐stability and energy conversion capability performance. The obtained composite exhibited 10‐fold higher thermal conductivity than that of the pristine PCM with greatly enhanced shape‐stability up to 120 °C.…”

Efficient photothermal conversion of Fe2O3–RGO guided from ultrafast quenching effect of photoexcited state

“…With the continuing decrease in fossil fuels, solar energy has become an important part of human energy and has been utilized continuously because of its abundance, inexhaustibility, and environmental friendliness 1‐3 . Solar energy thermal utilization can be used in power generation, 4‐8 sewage treatment, 9 seawater desalination, 10‐15 solar water heaters, 16,17 and many other fields due to its ease in use. The utilization of photothermal materials is indispensable to improve the efficiency of solar thermal energy.…”
