| titleOfInvention | Preparation and application of cobalt-graphene composite material for absorbing electromagnetic waves |
| abstract | The invention provides a method for preparing a cobalt-graphene composite wave-absorbing material in a normal-temperature water-phase system by using a one-step reduction method, belonging to the technical field of preparation of nano metal powder in a metal functional material. The method comprises the steps of adding an aqueous solution containing cobalt ions into an alkaline graphene oxide solution with a certain concentration at normal temperature, and then adding a reducing agent to synchronously reduce graphene oxide and metal cobalt from the solution to obtain the cobalt-graphene composite material. The cobalt-graphene composite wave-absorbing material is prepared by reducing cobalt ions and graphene oxide by a one-step method for the first time, is very simple to operate, low in energy consumption and low in cost, can be used for absorbing electromagnetic waves in a certain frequency range, and is wide in effective wave-absorbing frequency and high in efficiency. |
