Graphene–nickel/ n -carboxylic acids composites as form-stable phase change materials for thermal energy storage
Abstract(#br)Superoleophilic graphene–nickel foam (PDMS–G–NF), which was prepared by coating graphene nanosheets onto nickel foam followed by surface modification with polydimethylsiloxane (PDMS), was used as porous supporting material to prepare form-stable phase change materials (PCMs) composites. Owing to the strong hydrophobic and superhydrophilic wettability of PDMS–G–NF, PCMs can be absorbed spontaneously into PDMS–G–NF and can stay stable without leakage even over their melting points.
