NOVELTY - Preparing graphene/polyacrylic acid copolyester/fabric flexible composite electrode material involves carrying out in-situ copolymerization reaction by mixing acrylic acid, methyl acrylate, ethyl acrylate and graphene to obtain a graphene/polyacrylic acid copolyester emulsion. The emulsion is then impregnated with the fabric to obtain a graphene/polyacrylic acid copolyester/fabric flexible composite electrode material for brain electrical collection. USE - Method for preparing graphene/polyacrylic acid copolyester/fabric flexible composite electrode material used for brain electricity collection. ADVANTAGE - The method enables to prepare graphene/polyacrylic acid copolyester/fabric flexible composite electrode material, that has electrical conductivity, durability, stability, etc., fully meet the requirements of brain electrical collection, can be worn and used repeatedly for a long time, and do not need to apply conductive paste, and greatly improved the comfort of the subject, contact with the skin and continuous test results for 1 week showed that with the monitoring time, and quality of the electroencephalogram (EEG) signal collected by the electrode is stable, the resistance value of the electrode does not change significantly, and the electrode has a good effect.
