Thermal conductivity and heat transfer performance enhancement of phase change materials (PCM) containing carbon additives for heat storage application

Silver incorporated microencapsulation of n-hexadecane and n-octadecane appropriate for dynamic thermal management in textiles

“…In order to improve the thermal conductivity of PCMs, researchers have proposed various thermal response improvement techniques, which are mostly concentrated on incorporating metal and nonmetal fillers or their mixtures into PCMs [14,18], insertion of PCMs into finned tubes or plates of different configurations [19], dispersion of high thermal conductivity Carbon Nano Tubes (CNTs) and Carbon Nano Fibers (CNFs) [20,21,22,23], graphite [24], exfoliated graphite [25,26], graphene [27] or boron nitride [28] into PCMs, or doping of PCM by in-situ reduction of metal salt solutions [29]. Despite extensive previous research efforts on thermal conductivity improvement of PCMs, development of advanced composites of PCMs with good thermal conductivities has been still under investigation.…”

Enhanced thermal conductivity of n-octadecane containing carbon-based nanomaterials

“…The same material was used by Fan et al [27] to investigate enhanced thermal conductivity of PW at temperatures between 10 and 50 °C. Choi et al [28] prepared PCM (stearic acid) with carbon additives, i.e. MWCNT, graphite, and graphene and measured the thermal conductivity by the THW method.…”

Form-stable LiNO 3 –NaNO 3 –KNO 3 –Ca(NO 3 ) 2 /calcium silicate composite phase change material (PCM) for mid-low temperature thermal energy storage

“…Moreover, thermal conductivity of the composite PCM can be increased by introducing some additives with high thermal conductivity, such as metal particles and graphite [35,36]. In this paper, graphite was considered as thermal conductivity enhancer due to its bargain price.…”
