Abstract：Graphene is a new kind of carbon material, which has two dimensional structure and many excellent properties。 The three dimensional assembly of graphene is the current research hotspot。 This material has good flexibility, excellent mass transfer performance and wide application。 Therefore, it has important practical significance to achieve large number of graphene assembly。 Data show that graphene has wide application prospects in sewage treatment。 Based on this background, we have studied the preparation and properties of Shi Moxi polymer。

First, the preparation of graphene oxide as a raw material for graphene polymer, verified the feasibility of improving the preparation of the Hummers method。 Then, graphene sponge was prepared by directional solidification and freeze drying by using the graphene oxide as a raw material and hydrazine hydrate as a reducing agent。 Secondly, the prepared graphene oxide and graphene sponge were characterized, and the microstructure, chemical composition and electrical conductivity were analyzed。 Finally, the adsorption properties of graphene sponge on copper ions were analyzed。 The influence of different factors on the adsorption properties of graphene sponge was studied from the aspects of sponge quality, initial concentration of solution and adsorption time, so as to provide references for optimizing the process。
