▎ 摘　　要

NOVELTY - An adsorption material (10) comprises a graphene scroll (11) of a graphene sheet wrapping along an axis (13), and a modifier (15) grafting on an interlayer and outside of the graphene scroll and containing a hydrophilic group. The graphene scroll has a spiral shape at a cross-section perpendicular to the axis. USE - Adsorption material is used in heat pump (claimed) of air-conditioning unit, for adsorbing/desorbing refrigerant. ADVANTAGE - The adsorption material has excellent water adsorption/desorption property. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of adsorption material, which involves mixing a graphite and an intercalator to form an intercalated graphite (G1), mixing the intercalated graphite (G1) and the modifier to form a mixture, and applying a microwave to the mixture to form an intercalated graphite (G2), putting the intercalated graphite (G2) in an alcohol for a supersonic vibration to form the adsorption material; and (2) adsorption heat pump, which comprises an adsorption/desorption portion including the adsorption material for adsorbing/desorbing a refrigerant, an evaporation portion for evaporating the refrigerant, connected to the adsorption/desorption portion, and a condensation portion for condensing the refrigerant, connected to the adsorption/desorption portion. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the adsorption material. Adsorption material (10) Graphene scroll (11) Axis (13) Modifier (15)
