Graphene adsorbing material, preparation method therefor and application thereof, and cigarette filter tip and cigarette

Abstract

A graphene adsorbing material, a preparation method therefor and application thereof, and a cigarette filter tip and a cigarette are provided. The graphene adsorbing material comprises a fiber carrier, graphene and doped elements wherein the graphene and the doped elements are loaded on the fiber carrier and the doped elements comprise at least one of Al, Si and Fe. The graphene adsorbing material is obtained by contacting the fibers with the graphene material to load the graphene material on the fibers. By introducing the graphene and the doped elements in the fiber carrier, harmful substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke can be specifically adsorbed, filtered and removed; while nicotine and the other harmless substances are retained, and thus the smoking taste of a cigarette is not affected. The cigarette filter tip can effectively adsorb cancerogenic substances with a type of fused aromatic hydrocarbons such as benzopyrene in smoke to reduce harm of smoking; meanwhile, the pleasure of smoking and the mellow taste of the smoke are not affected. Besides, the graphene adsorbing material can also prevent the phenomenon that a cigarette holder gets mildewed due to humid environment and the other factors.
