NOVELTY - Preparing graphite oxide/polyvinylidene fluoride composite material comprises (i) dispersing polyvinylidene fluoride and graphene oxide in ethanol solution under ultrasonic condition for 1-4 hours to obtain a mixed solution; (ii) heating mixed solution under vacuum at 60-80 degrees C for 2-6 hours, adding methylene bicyclohexylamine, stirring and mixing for 10-30 minutes; (iii) heating to 40-60? C for 2-4 hours under vacuum at 5-10 degrees C/minute and curing at 90-110 degrees C for 2-4 hours. USE - The method is useful for preparing graphite oxide/polyvinylidene fluoride composite material. ADVANTAGE - The method: produces composite material with high dielectric properties with a dielectric constant of 8 (0.1 Hz) and a dielectric loss of 0.1 (0.1 Hz).
