High-efficiency cigarette filter tip containing nano-carbon material

The invention provides a high-efficiency cigarette filter core containing a nano-carbon material and a cigarette filter tip prepared from the same. The cigarette filter core is characterized in that nano-carbon particles which are absorbed on fiber bundles, are subjected to surface modification and have rich active groups and high specific surface area can remove a plurality of free radicals as well as poisonous and harmful substances such as benzopyrene (a, b) and partial cigarette tar in cigarette smoke through physical and chemical absorption when the cigarette smoke passes through the fiber bundles of the filter core of the filter tip. To improve the action effect, one or more auxiliary substances can be synchronously absorbed on the fiber bundles. The filter core does not affect the unique taste and filtration aeration of cigarettes during the smoking, and can effectively remove a plurality of the poisonous and harmful substances in the smoke and improve the mouthfeel at the sametime. The filter core can be used for producing disposable cigarette filter tips, filter tips on the cigarettes, and filter tips in matroospipes to reduce the hazard caused by smoking.
