▎ 摘　　要

NOVELTY - Preparing electromagnetic shielding material involves dispersing graphene oxide and carbon nanotubes in solvent I and then subjecting the dispersed material to perform ultrasonic stripping to obtain graphene oxide-carbon nanotube mixed solution. The obtained solution is added with aqueous solution of metal salt and surfactant to obtain metal salt-graphene oxide-carbon nanotube mixed solution. The obtained solution is irradiated with gamma ray or electron beam to obtain the desired product. USE - Method for preparing electromagnetic shielding material (claimed). ADVANTAGE - The method enables to prepare electromagnetic shielding material in simple and cost-effective manner, and with mild reaction conditions and strong applicability.
