▎ 摘　　要

NOVELTY - The preparation method of composite material involves adding 1-20 g/l cubilose aqueous solution to 0.01-100 g/l silver nitrate aqueous solution and then reacting at 80-200 degrees C for 100-600 minutes, washing using ethanol and deionized water and then centrifuging, dispersing in deionized water and then drying at room temperature for 24 hours, soaking in ethanol-graphene dispersion liquid, adding glutaraldehyde to the mixture and then reacting for 30-300 minutes, washing using deionized water and ethanol and naturally drying. USE - The method is useful for preparation of composite material. ADVANTAGE - The method enables preparation of composite material with excellent electrical conductivity, antibacterial properties and thermal and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for composite material prepared by the method.
