NOVELTY - Graphene anion heating inner heating quilt comprises quilt cover and a quilt core arranged in the quilt cover. The core is graphene anion hollow cotton filler. The graphene anion hollow cotton is prepared by e.g. (i) pulverizing hollow cotton to obtain hollow cotton granules, (ii) adding hollow cotton particles into the aqueous solution of the silane coupling agent, ultrasonically dispersing for 15-20 minutes to obtain dispersion, (iii) mixing graphene oxide and far-infrared ceramic powder into a solvent at mass ratio of 4-6:1, ultrasonically dispersing for 15-20 minutes to obtain dispersion, allowing to stand and filtering to obtain far-infrared ceramic powder intercalated graphene oxide precipitate, and (iv) adding the precipitate obtained in the step (iii) into the dispersion obtained in the step (ii), ultrasonically dispersing for 15-20 minutes, sealing the reaction system in a microwave oven with nitrogen, setting the microwave output power to 800 W, and heating for 15-30 minutes. USE - The quilt is useful for promoting blood circulation, preventing human aging and premature aging. ADVANTAGE - The quilt: regulates the surrounding environment; has durable antibacterial and bactericidal properties; can kill harmful bacteria to the human body; does not hurt the human body; has excellent deodorizing performance; removes peculiar smell; releases negative ions; does not easy to breed bacteria; has stable structure; is durable and not easy to deform. DETAILED DESCRIPTION - Graphene anion heating inner heating quilt comprises quilt cover. The core placed in the quilt. The core is graphene anion hollow cotton filler. The graphene anion hollow cotton is prepared by (i) pulverizing hollow cotton to obtain hollow cotton granules, (ii) adding hollow cotton particles into the aqueous solution of the silane coupling agent, ultrasonically dispersing for 15-20 minutes to obtain dispersion, (iii) mixing graphene oxide and far-infrared ceramic powder into a solvent at mass ratio of 4-6:1, ultrasonically dispersing for 15-20 minutes to obtain dispersion, allowing to stand and filtering to obtain far-infrared ceramic powder intercalated graphene oxide precipitate, (iv) adding the precipitate obtained in the step (iii) into the dispersion obtained in the step (ii), ultrasonically dispersing for 15-20 minutes, sealing the reaction system in a microwave oven with nitrogen, setting the microwave output power to 800 W, heating for 15-30 minutes, filtering the product mixture and collecting to obtain precipitated product, washing the precipitated product with ethanol and deionized water until neutral, and drying the precipitated product, (v) mixing the precipitate obtained in the step (iv) with the hollow cotton particles, and the screwing and extruding, carrying out melt spinning, and opening to obtain graphene anion hollow cotton.
