| titleOfInvention | A kind of preparation method of sulfonated polyether ether ketone/sulfonated graphene oxide composite proton exchange membrane |
| abstract | The invention discloses a preparation method of a sulfonated polyether ether ketone/sulfonated graphene oxide composite proton exchange membrane, and relates to the field of composite materials. The invention prepares SGO-C≡C; concentrated sulfuric acid dissolves polyether ether ketone to prepare sulfonated Polyetheretherketone; SPEEK-CH 2 N 3 prepared by chloromethylation reaction and azide reaction; SPEEK-SGO prepared by CuBr catalyzed click chemistry reaction between alkyne-azide; prepared by solution casting blend phase transformation method The SPEEK-SGO composite membrane realizes the preparation and modification of the sulfonated polyetheretherketone membrane; this experiment improves the proton conductivity, Coulomb efficiency and larger power density of the polymer membrane in the fuel cell; the invention is applied to the chemical field . |
