▎ 摘　　要

NOVELTY - Preparing reduced graphene oxide (rGO)/ cobalt nano-rod composite wave-absorbing material involves adding the cobalt nano-rod into the rGO dispersion, performing ultrasonic treatment, centrifuging, and drying the product after ultrasonic treatment, and then grinding into powder to obtain the rGO/ cobalt nanorod powder. USE - Method for preparing reduced graphene oxide (rGO)/ cobalt nano-rod composite wave-absorbing material. ADVANTAGE - The preparation method is simple and convenient, easy to operate, low in cost and easy to realize industrial mass production. The prepared wave-absorbing material is low in density, applicable to wide frequency, good in physicochemical property and machining property, and low in optimal reflection loss value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a rGO/cobalt nano-rod composite wave absorbing material, which comprises one dimensional cobalt nano-rods covered by rGO, and is compounded with PVDF.
