NOVELTY - Preparing nickel phosphide/reduced graphene oxide for electromagnetic absorption material comprises (i) adding certain amount of nickel chloride hexahydrate, hexadecylamine, triphenyl phosphite, octadecene and graphene into 50 ml three-necked bottle, (ii) reacting the mixture for a certain period of time under nitrogen protection and certain temperature, and (iii) collecting the reacted samples, centrifuging with n-hexane and absolute ethanol, and drying at a certain temperature to be used for electromagnetic absorption testing. USE - Preparing nickel phosphide/reduced graphene oxide for electromagnetic absorption material. ADVANTAGE - The method has low cost and simple preparation technique, and can be adjusted by adding amount of hexahydrate nickel chloride, to control the amount of nickel phosphide on graphene, so as to affect the efficiency of electromagnetic absorption. The prepared nickel phosphide/reduced graphene oxide is used for electromagnetic absorbing material with the most excellent electromagnetic absorption efficiency.
