▎ 摘　　要

NOVELTY - A graphene oxide filled binary complex cigarette filter is prepared by impregnating inner cigarette filter with improved uniformity of 0.2-1 mg/ml graphene oxide dispersion by Hummers rule of law, where the dropwise adding quantity of dispersion is 0.3-1 ml. USE - Graphene oxide filled binary complex cigarette filter. ADVANTAGE - The cigarette filter selectively reduces the cigarette main stream smoke of phenolic compound content, to 100%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing a graphene oxide filled binary complex cigarette filter.
