Abstract

The invention relates to novel oil absorption cotton. The novel oil absorption cotton comprises a porous cotton cloth layer, a filtering layer and a graphene aerogel layer with a 3D (Three Dimensional) porous framework, which are arranged in a laminated manner, wherein the graphene aerogel layer is nitrogen-doped graphene aerogel, and the doping mass percent of nitrogen is 50 percent to 80 percent; the porous cotton cloth layer is made of super-hydrophobic/super-oleophilic polypropylene. The porous cotton cloth layer comprises a first cotton cloth layer and a second cotton cloth layer; the filtering layer comprises a first filtering layer and a second filtering layer; the first filtering layer and the second filtering layer are arranged on two opposite side faces of the graphene aerogel layer respectively; the first cotton cloth layer is arranged at one side, far away from the graphene aerogel layer, of the first filtering layer; the second cotton cloth layer is arranged at one side, far away from the graphene aerogel layer, of the second filtering layer. The novel oil absorption cotton provided by the invention can be repeatedly utilized and the oil absorption efficiency is not remarkably reduced; the novel oil absorption cotton has an ultrahigh oil absorption rate and ultrahigh oil absorption efficiency.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a new type of oil-absorbing cotton, in particular to a new type of oil-absorbing cotton whose oil-absorbing efficiency will not decrease significantly with the increase of the repeated use times of the oil-absorbing cotton. Background technique [0002] With the continuous development of world industry, the discharge of oil pollution is increasing day by day, and there are more and more ways and opportunities for oil leakage, especially large-scale oil leakage accidents caused by maritime shipping. Marine oil pollution has seriously threatened the ecological environment of the coastal waters, and it is urgent to control the oil pollution of the coastal water environment. However, there is still a lack of effective methods for marine oil pollution control, mainly relying on reducing pollution opportunities, pre-treating oily wastewater from pollution sources, and con...
