NOVELTY - Preparation of composite phase-change material involves adding graphene oxide powder in deionized water, stirring to uniformly disperse graphene oxide powder, obtaining graphene oxide solution, adding organic phase-change material, mixing, transferring the resultant material into a microwave reactor, heating with vigorous magnetic stirring, placing the resultant material in a vacuum oven and drying. USE - Preparation of composite phase-change material (claimed). ADVANTAGE - The method provides composite phase-change material having excellent thermal conductivity and stability, by simple and economical process in a short period of time.
