A novel electromagnetic material 4, 4'-oxydianiline molecular imprinted polymer composite poly 4, 4'-oxydianiline (4, 4'-ODL-MIP/P-4, 4'-ODL) was prepared on the surface of graphene modified pencil electrode (G-PEC) by means of the secondary electrochemical polymerization. The effects of the effective conductive length, the concentration of graphene, pH of buffer, the concentration ratio of 4, 4'-oxydianiline to functional monomer acrylamide, the range of scanning potential, the number of scanning cycles, scanning rate and elution time on the charge of composite materials were investigated. The testing results of the vector network analyzers showed that as-synthesized composite material exhibited a reflection loss of -10.57dB at 12.56MHz, and the effective electromagnetic wave absorption rate reached 90%. However, the reflection loss of a single 4, 4'-ODL-MIP and graphene were both higher than -10 dB, the effective electromagnetic wave absorption rates were only about 68% and 60%, respectively. Therefore, the composite material exhibited good wave absorbing properties.
