▎ 摘  要

NOVELTY - Type oil-absorbing cotton comprises porous cotton layer are laminated, a filter layer and a graphene aerogel having a 3 dimensional porous skeleton layer. The graphene aerogel layer is a graphene aerogel doped with nitrogen. The doped mass percentage of nitrogen is 50-80%. The porous cotton is set with superhydrophobic/ lipophilic polypropylene material. The porous fabric layer comprises a first cotton cloth layer and the second cotton cloth layer. The first filter layer and the second filtering layer are set two sides of the graphene aerogel layer opposite to the first cotton layer. USE - Used as type oil-absorbing cotton. DETAILED DESCRIPTION - Type oil-absorbing cotton comprises porous cotton layer are laminated, a filter layer and a graphene aerogel having a 3 dimensional porous skeleton layer. The graphene aerogel layer is a graphene aerogel doped with nitrogen. The doped mass percentage of nitrogen is 50-80%. The porous cotton is set with superhydrophobic/ lipophilic polypropylene material. The porous fabric layer comprises a first cotton cloth layer and the second cotton cloth layer. The filter layer comprises a first filter layer and the second filtering layer. The first filter layer and the second filtering layer are set two sides of the graphene aerogel layer opposite to the first cotton layer. The first filtering layer is far away from one side of the graphene aerogel layer of the second cotton layer and set between the second filter layer far away from one side of the graphene aerogel layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the type oil-absorbing cotton.
