▎ 摘  要

NOVELTY - Preparing silver/reduced graphene oxide composite material involves de-oiling an aluminum substrate sample in a degreasing liquid at 60 degrees C for 5 minutes, after cleaning aluminum substrate sample with water. The degreased sample is activated in an activation solution at 25 degrees C for 2 minutes and cleaned with water. The activated sample is immersed in 25 degrees C , immersing zinc in the liquid for 1 minute and clean it with water, dehydrating sample after zinc immersion in a zinc solution at 25 degrees C for 30 seconds, and cleaning it with water. The zinc immersion solution at 25 degrees C is immersed in zinc for 1 minute and cleaned with water. The sample after second immersion zinc is electroplated for 5 minutes in a silver plating solution at 25 degrees C for a current density of 1- 5 ampere per square decimeter. The pole pitch is 5 centimeter, and cleaned with water. USE - Method for preparing silver/reduced graphene oxide composite material. ADVANTAGE - The method enables to prepare silver/reduced graphene oxide composite material which has high conductivity and excellent corrosion resistance and stability. DETAILED DESCRIPTION - The silver-plated sample is bidirectional pulse plated at 40 degrees C in composite silver-plated graphene oxide plating solution for 20-40 minutes, and bidirectional pulse plating current density is 1 -5 ampere per square decimeter, and pole pitch is 5 centimeter, and cleaned with water to obtain silver/reduced graphene oxide composite material.
