The x wt% graphene-Ti composites (x = 0, 0.2, 0.3 and 0.4) were obtained using the powder metallurgy method. The X-ray diffraction results demonstrated that the peak intensity of graphene increased monotonically with increasing graphene content. Furthermore, the number of grain boundary and interface between graphene and matrix increased as graphene increased, which led to a sharp rise of thermal resistances. The thermal conductivity and specific heat capacity of composites initially decreased drastically with addition of graphene, but then increased with increasing graphene content from 0.2 to 0.4 wt%. This phenomenon was connected with the graphene content and the characteristics of Ti matrix (pores, grain boundary and interface between graphene and matrix). The variation of the compressive strength of composites was attributed to the interaction effects of the average grain size of the Ti matrix (d m ) and the volume fraction (V f ) and aspect ratio (k) of graphene.

“…Thermal properties, such as specific heat, thermal conductivity, melting point, melting enthalpy were investigated by differential scanning calorimetry (DSC) and laser flash apparatus (LFA). Testing results validation had been reported in [28]. In order to avoid duplication, the corresponding contents will not be presented in present paper.…”

“…As pointed in Ref. [28], the nanomaterial has large specific surface area which is beneficial to form nanolayer; and the formation of nanolayer is the reason that the nanomaterial can enhance PCM specific heat. At the same time, the large specific surface area results in large surface energy, which accelerates nanomaterial aggregation and forming nanomaterial block.…”

“…Improving PCM thermal conductivity can make the temperature distribution more uniform, which is beneficial to both the system efficiency and life. In order to improve PCM thermal conductivity, Tao et al [28] prepared carbonate salt/carbon nanomaterial CPCM with four kinds of carbon nanomaterials by solution evaporation method and the effects of nanomaterial microstructure and mass fraction on CPCM thermal performance were investigated.…”
