NOVELTY - Multi-functional integrated filter comprises filtering component and filtering medium, where filtering medium comprises 5-20 wt.% graphene material, 20-60 wt.% filling material and amonut of adhesive. USE - Multi-functional integrated filter. ADVANTAGE - The multi-functional integrated filter is cost effective, easy to obtain raw materials, suitable for industrial production, has simple preparation, high economical performance ratio, good flexibility, reliability diversity characteristics, and excellent comprehensive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing multi-functional integrated filter, which involves: (A) adding graphene material into 75% ethanol solution in mass ratio of 1:3.2-4.5, adding 0.03-0.07 times of dispersant to total amount of graphene material, under ultrasonic dispersion for 15-25 minutes to obtain graphene dispersion ; (B) adding filling material to crusher for crushing and sieving to obtain 80-200 meshes powder; (C) adding obtained powder into obtained graphene dispersion, adding binder, stirring and mixing for 2-5 hours at temperature of 98-125 degrees C to obtain filter medium; and (D) putting obtained filter medium into filter module, cooling and solidifying to obtain final product.
