NOVELTY - The preparation of graphene-polymer composite aerogel perfume filter rod involves adding acrylic acid or acrylamide, N,N'-methylenebisacrylamide, initiator, graphene oxide and deionized water, stirring evenly, ultrasonically treating, injecting into mold, reacting, adding cleaning solvent, cleaning till swelling equilibrium is reached, freeze drying or carbon dioxide supercritical drying to obtain filter graphene polymer composite aerogel filter rod, and spraying perfume fragrance agent to obtained product. USE - Preparation of graphene-polymer composite aerogel perfume filter rod (claimed). ADVANTAGE - The graphene-polymer composite aerogel filter rod has high specific surface area, excellent favor adsorption and perfume performance, physical and chemical performance, and excellent interception effect to flue gas. The method ensures preparation of graphene-polymer composite aerogel perfume filter rod by simple operation with low raw material cost, improves appearance of product, and provides different fragrance and flavor of cigarette by loading different perfumes. DETAILED DESCRIPTION - The preparation of graphene-polymer composite aerogel perfume filter rod involves adding 1 pt. wt. acrylic acid or acrylamide, 0.001-0.01 pt. wt. N,N'-methylenebisacrylamide, 0.05-0.005 pt. wt. initiator, 0.005-0.05 pt. wt. graphene oxide and 10-50 pts. wt. deionized water, stirring evenly, ultrasonically treating at 20 degrees C for 20 minutes, injecting into mold, reacting at 50-70 degrees C in water bath for 0.5-6 hours, adding cleaning solvent, cleaning for 12-48 hours till the swelling equilibrium is reached, freeze drying at -5 to -10 degrees C for 1-6 hours, or carbon dioxide supercritical drying to obtain graphene polymer composite aerogel filter rod, spraying perfume fragrance agent on the obtained product. The initiator is sodium persulfate, ammonium persulfate, potassium persulfate, sodium sulfite-saturated hydrogen peroxide or azobisisobutyronitrile imidazole hydrochloride.
