Abstract
The invention provides a method for preparing a graphene membrane electrode with overlarge area and high quality, which comprises the following steps of: placing a spiral or S-shaped quartz tank provided with a metal foil into a reactor by adopting a chemical vaporous deposition method, introducing a hydrocarbon for catalytic decomposition to obtain a graphene membrane on the metal foil; attaching an organic colloid on the product to obtain an organic colloid/grapheme/metal foil combination; removing the metal foil by using metal foil corrosive liquid to obtain an organic colloid/grapheme combination; taking out the product in the previous step by using a substrate, placing the product into deionized water, washing and drying to obtain an organic colloid/grapheme/ substrate combination; finally, removing the organic colloid by using an organic solvent, taking out and naturally drying to obtain the graphene membrane electrode with overlarge area and high quality, which is positioned on the substrate. The method has simple operation step, large area of the obtained product, low raw material cost, high electrical conductivity and high light transmittance, and is mainly used for the fields of semiconductors, solar batteries, liquid crystal panel display, and the like.
