AB  - Compositephase change materials (PCM) of stearic acid/graphene oxide were prepared by thiol-alkyneclick coupling reaction. Stearic acid was firstly modified with propargyl tointroduce thiol-yne clickable sites. Different amounts of graphene oxide wereadded to thiol-alkyne clickable formulation. To evaluate phase changeproperties of PCMs differential scanning calorimeter (DSC) was used. Thermalstability and degradation profiles of PCMs were investigated. The structuralcharacterization of stearic propargyl ester and PCMs was performed by ATR-FTIRspectroscopy. The addition of graphene oxide increased the maximum weigh losstemperature from 328 to 351 ˚C with respect to the base formulation. Moreover,the crosslinking of stearic acid prevented the leakage of PCMs.
