▎ 摘　　要

NOVELTY - Preparing polymer nanocomposite electromagnetic shielding material involves utilizing ferric chloride, ferrous chloride, organic surface active agent, graphene and sodium hydroxide solution and mixing and stirring and then filtering. The resulting composite nanomaterials are pre-blended with nylon 66 and the resulting materials are melt blended. USE - Method for preparing polymer nanocomposite electromagnetic shielding material (claimed) used in electronic technology, communication and traffic industry. ADVANTAGE - The method enables to prepare polymer nanocomposite electromagnetic shielding material, which has high electromagnetic shielding ability and excellent comprehensive performance.
