Abstract
The growing need for energy storage prompts constant work on this subject. A widely progressive energy storage method uses shape-stabilised phase change materials (ssPCMs), particularly those using liquid-solid phase transition. Due to their relatively low thermal conductivity, which results in prolonged charging and discharging, additives are used to increase the thermal conductivity value. This paper presents the results of the studies on the properties of PCM (paraffin wax) stabilised by methyltrimetoxysilane (MTMS)-based aerogels doped with reduced graphene oxide (rGO). Two methods of rGO doping were tested - doping the PCM and doping the aerogel matrix. The MTMS-based aerogel synthesis was developed to ensure the stability and homogeneity of rGO within the aerogel structure by using a surfactant and reducing condensation time. Two methods of PCM immobilisation were studied: dry and wet, utilising doped and undoped aerogels. This paper examined the PCM loading and stability of the obtained ssPCMs during phase transition cycles in air and aqueous conditions. The results show that the rGO doping does not affect the loading capacity of the MTMS matrix, which was about 84 % and the ssPCM stability, with a maximum observed leakage of 1.04 percentage points after cycles in water. The investigated samples are characterised by good thermal properties - latent heat of fusion and thermal conductivity. However, in rGO-doped ssPCMs, relocation of the dopant was observed during the melting-solidification cycles.
