▎ 摘　　要

NOVELTY - A graphene ceramic nano-composite material filter comprises mouth piece (201), filtration column (202) comprising graphere ceramic nano-composite material (205), front plug, back plug (204), cigarette holding section (203), and cylindrical pipe to fix the cigarette. The filtration column is positioned between the front plug and back plug. The graphene ceramic nano-composite material filter adsorbs the toxic compounds from cigarette smoke. The toxic compounds adsorbed from cigarette smoke are ammonia, formaldehyde, mainstream total particulate matter, nicotine, tar and nitrosamines. The functional groups are incorporated onto the surface of the graphene ceramic nano-composite material by chemical functionalization. The functional groups are chosen from oxygen-based functional groups, sulfur-based functional groups, nitrogen-based functional groups, halogen-based functional group, phosphorus-based functional group, and boron-based functional groups. USE - Filter used for cigarette, cigars, cigarillos, little cigars, bidis, hookah, kreteks, tobacco pipes, and e-cigarettes. ADVANTAGE - The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke, effectively removes the toxic organic chemical compounds from inhaled smoke, and ensures minimum effect on the nicotine content of the inhaled smoke. DETAILED DESCRIPTION - A graphene ceramic nano-composite material filter comprises mouth piece, filtration column comprising graphere ceramic nano-composite material, front plug, back plug, cigarette holding section, and cylindrical pipe to fix the cigarette. The filtration column is positioned between the front plug and back plug. The graphene ceramic nano-composite material filter adsorbs the toxic compounds from cigarette smoke. The toxic compounds adsorbed from cigarette smoke are ammonia, formaldehyde, mainstream total particulate matter, nicotine, tar and nitrosamines. The functional groups are incorporated onto the surface of the graphene ceramic nano-composite material by a chemical functionalization depending on the toxins or compounds to-b-adsorbed from cigarette smoke. The functional groups are chosen from oxygen-based functional groups, sulfur-based functional groups, nitrogen-based functional groups, halogen-based functional group, phosphorus-based functional group, and boron-based functional groups. The oxygen-based functional groups are added on the surface of graphene ceramic nano-composite material by heating the graphene nano-composite material in an ambient air and chemical treatment. The sulfur-based functional groups, nitrogen-based functional groups, halogen-based functional group, phosphorus-based functional group, and boron-based functional groups are added on the surface of graphene ceramic nanocomposite material by a chemical treatment specific to the desirable functional groups. The functional groups are added on the surface of graphene ceramic nano-composite material to remove toxic compounds from cigarette smoke based on the affinity of toxic compounds towards the functional groups. The cylindrical pipe to fix the cigarette is designed to fit with smoking products, and is tapered from inside to fit a cigarette. The filter is configured as a standalone product.
