NOVELTY - Alkylamine functionalized graphene/paraffin shaped phase change material is consists of 10-30 wt.% polyolefin elastomer, 1-5 wt.% alkylamine functionalized graphene and 65-85 wt.% paraffin. USE - Alkylamine functionalized graphene/paraffin shaped phase change material. ADVANTAGE - The alkylamine functionalized graphene/paraffin shaped phase change material has higher phase change enthalpy value and heat transfer efficiency, and has excellent thermal stability and will not collapse or flow within the operating temperature range, and have broad application prospects in thermal energy storage and management. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing an alkylamine functionalized graphene/paraffin shaped phase change material, which involves: (A) dissolving the alkylamine functionalized graphene in toluene and disperse it by ultrasonic for 30 minutes to obtain a homogeneous solution; (B) dissolving polyolefin and paraffin in toluene in a three-necked flask, heating and stirring at 80 degrees C for 30 minutes, after the dissolution is complete, slowly dropping the homogeneous solution into obtained container and reflux for 10 hours; and (C) distilling off toluene under reduced pressure, and drying residue to constant weight in a vacuum oven at 35 degrees C, after cooling to room temperature to obtain phase-change material.
