The invention discloses a poly glucosamine hexanedioic acid vinyl ester material for reducing the content of phenol type substances. The composite material is the material which takes a porous material as a carrier and alternately loads polyanions and hydrophilic polycations on the porous material in the way of carrying out self-assembly layer upon layer, and the hydrophilic polycations are loaded on the outmost layer of the porous material, wherein the hydrophilic polycations are poly glucosamine hexanedioic acid vinyl ester hydrochloride. The composite material can be used for preparing cigarette filters and can be prepared into the binary compound cigarette filters or the three-section compound cigarette filters. The poly glucosamine hexanedioic acid vinyl ester material can reduce thephenol type harmful substances in cigarette smoke by utilizing the water selectivity in the composite material; simultaneously, as a large number of flavor organic compounds can not be dissolved in water, the poly glucosamine hexanedioic acid vinyl ester material can avoid the loss of flavor components and keep the inherent quality of cigarettes.
