▎ 摘　　要

NOVELTY - A conjugated polymer/graphene oxide composite material is prepared by mixing balance solvent and 0.5-30 pts. wt. conjugated polymer, dispersing 0-99 (preferably 1-99) wt.% graphene oxide solution in the solution, irradiating obtained mixture using UV light having a wavelength of 200-450 nm at 5-99 degrees C for 10 minutes to 10 hours, centrifuging, and filtering. USE - Method of preparing a conjugated polymer/graphene oxide composite material (claimed) for solar battery, a plane display, photo-electric device, a capacitor or gas-sensitive sensor. ADVANTAGE - The method is simple, low cost and convenient.
