【Abstract】 Conductive materials made of meta-aramid(PMIA) have shown outstanding application in anti-static, conductive, EMI shielding, electrical heating, etc. due to excellent characteristics such as high strength and modulus, softness, light weight, flame retardancy and heat resistance of PMIA. In this paper, the preparation methods of PMIA conductive materials are reviewed, including electroless plating, low temperature plasma treatment, blend spinning,wet spinning, surface etching, γ-ray irradiation, surface coating, surface grafting, solution casting, electrostatic spinning and magnetron sputtering. The applications of PMIA in EMI shielding, personal thermal management and pressure sensing are expounded, aiming to provide technical for preparing high-performance materials. The preparation technology of PMIA-based EMI shielding materials and portable flexible electronic devices is prospected.更多还原
