NOVELTY - Fluorine rubber modified carbon aerogel, is claimed. The fluorine rubber is prepared by mixing adding cross-linking agent and auxiliary cross-linking agent, taking out, cutting, adding solvent to obtain the fluorine rubber mixed solution, using fluorine rubber mixed liquid to dip the carbon aerogel, volatilizing the solvent, adhering the fluorine rubber film to the surface of the carbon aerogel skeleton, heating to vulcanize and crosslink the adhesive film, the fluorine rubber molecular chain reacts with the amino on the aerogel skeleton to generate a composite of carbon nano-tube and fluorine rubber containing carbon-nitrogen double bond, the fluorine rubber physical coating modification and surface chemical modification of the carbon aerogel. USE - The aerogel is useful in the fields of flexible sensing, hydrophobic oil absorption, flame retardant and flameproof. ADVANTAGE - The aerogels has good elasticity, bending resistance, hydrophobicity, oil absorption, and flame retardancy, can withstand repeated bending and torsion without causing significant damage to the carbon aerogel skeleton. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the fluorine rubber modified carbon, comprising (i) adding the graphene oxide and aminated carbon nano-tube into de-ionized water, stirring, ultrasonically dispersing to prepare water dispersion, (ii) adding reducing agent in the water dispersion, stirring, ultrasonically dispersing, placing the solution into a sealed container, reducing at high temperature to obtain hydrogel, (iii) soaking the hydrogel in ethanol/ aqueous solution, placing into cold trap for low temperature freezing, placing in the freeze drier to freeze-dry to obtain the carbon aerogel, (iv) placing the fluorine rubber into a double-roller open mill for plasticating, adding cross-linking agent and assistant crosslinker for mixing, taking out, cutting, adding solvent, stirring uniformly to obtain the fluorine rubber mixed solution, (v) soaking the carbon aerogel in the fluorine rubber mixed solution, placing in the oven for vacuum drying, removing the organic solvent, covering the fluorine rubber film on the surface of the carbon aerogel skeleton, the carbon aerogel cannot be disposable the fluorine rubber mixed solution completely, repeating the above dipping-drying process until all the fluorine rubber mixed solution absorbed completely by the carbon aerogel, and (vi) heating in the aging box, and vulcanizing the fluorine rubber film.
