Method for preparing conducting polymer modified active carbon

Abstract

The invention discloses methods for making conducting polymer modified active carbon, relating to a method for preparing compound materials. The invention discloses two methods for preparing conducting polymer modified active carbon and application thereof in the field of environment purifying materials. The methods are characterized in that under the condition of an ultrasonic vibration or a solid phase reaction, a conducting polymer monomer is subjected to in situ polymerization reaction on the surface of the active carbon to obtain the active carbon / conducting polymer compound materials. The conducting polymer modified active carbon prepared by the methods still keeps higher specific surface area of the active carbon, has functionalities from the conducting polymer and excellent absorption performance to metal ions and organic materials in a water solution, and is a novel compound material for processing water pollution and purifying environment.

Description

technical field [0001] The invention relates to a method for preparing composite materials, in particular to a method for preparing conductive polymer-modified activated carbon used for purifying industrial sewage or dye water. Background technique [0002] Activated carbon is widely used as an adsorption material. It has strong adsorption and catalytic performance, acid and alkali resistance, heat resistance, insoluble in water and organic solvents, sufficient raw materials and easy regeneration. It is an environmentally friendly adsorption agent. Activated carbon is widely used in industrial waste treatment, solvent recovery, food and beverage purification, carrier, medicine, gold extraction, semiconductor application, battery and electric energy storage, etc. The broadening of application fields puts forward higher requirements on the performance of activated carbon, which further promotes the development of activated carbon in raw materials and preparation methods, and ...

Problems solved by technology

These composite materials use mesoporous carbon as a matrix, directly infiltrate polymers such as polymethyl methacrylate and polystyrene into the pores of mesoporous carbon to obtain physically mixed composite materials, and use this composite material to absorb vitamins. Or water treatment, etc., the disadvantage is that the preparation of mesoporous carbon itself is relatively complicated, and it is not easy to produce in batches.

Moreover, polymethyl methacrylate directly penetrates into the matrix, and is not organically combined with the matrix, so there are problems such as poor stability.
