NOVELTY - Preparing flexible conductive composite material by magnetic field regulating graphene arrangement involves preparing graphene oxide, ferrous chloride tetrahydrate, ferric chloride hexahydrate aqueous solution separately, and then blending at 15 degrees C for 10-15 minutes under vacuum mechanical stirring. Ammonia water is added to adjust the pH value to 10-11, water bath is stirred at 70-80 degrees C for 10-20 minutes, mixture is centrifugated, lower layer of sediment is separated and rinsed with deionized water to make it neutral. The obtained substance is dried at 40-60 degrees C for 10-12 hours to obtain magnetic graphene powder. The magnetic graphene powder and the polymer are ultrasonically dispersed in N, N-dimethylformamide. After being dispersed, the mixture is further blended, and the mixed solution is mechanically stirred in water bath at 80-90 degrees C for 10-15 minutes, and the same conditions are continued after adding 3,3'-dichloro-4,4'-diaminodiphenylmethane. USE - Method for preparing flexible conductive composite material by magnetic field regulating graphene arrangement. ADVANTAGE - The method has simple operation, easily available raw materials, and low preparation conditions.

The magnetic graphene powder and the polymer are ultrasonically dispersed in N, N-dimethylformamide. After being dispersed, the mixture is further blended, and the mixed solution is mechanically stirred in water bath at 80-90 degrees C for 10-15 minutes, and the same conditions are continued after adding 3,3'-dichloro-4,4'-diaminodiphenylmethane. The vacuum bath is mechanically stirred for 5-10 minutes. The mixture is poured into a petri dish coated with release agent and placed in uniform magnetic field generated by a strong magnet of neodymium iron boron (NdFeB) for 2 hours, and then dried in a vacuum oven at 150-160 degrees C for 100-110 hours to obtain flexible conductive composite material.
