Preparation and properties of myristic–palmitic–stearic acid/expanded graphite composites as phase change materials for energy storage

H2O2-microwave treated graphite stabilized stearic acid as a composite phase change material for thermal energy storage

“…Sarı and Karaipekli 40 chosen expanded graphite as support material to obtain composite PCMs, which can greatly enhance the mass fraction of PCM. Yuan's group [41][42][43][44][45] had a series of research works on expanded graphite composite PCMs with high thermal energy storage performance. Li et al 16 used graphite powder to produce graphene oxide and then skillfully stabilized stearic acid to prepare composite PCMs with adjustable thermal properties.…”

Hydrated salts/expanded graphite composite with high thermal conductivity as a shape-stabilized phase change material for thermal energy storage

“…4 displays the FTIR spectra of EG, hydrated salts, uncoated and coated hydrated salts/EG composite PCM. The FTIR spectrum of EG showed the characteristic absorption peaks at 1636 cm À1 and 3453 cm À1 , corresponding to the stretching vibrations of C@O and OH [27], respectively. The peaks at 1163 cm À1 and 619 cm À1 represented SAO stretching vibration and symmetric SAO stretching vibration [28], respectively.…”

Lauric–palmitic–stearic acid/expanded perlite composite as form-stable phase change material: Preparation and thermal properties

“…Compared with an ordinary room, the PCM wallboard room could greatly reduce the energy cost of HVAC systems and transfer electric power peak load to valley. Yang et al [13] prepared a MA-PA-SA ternary eutectic mixture by the method of combining theoretical calculation and experimental procedure. In order to enhance the thermal conductivity and prevent the leakage of the PCM, expanded graphite (EG) http with high thermal conductivity and porous structure was added in MA-PA-SA to prepare composite PCM.…”
