Preparation and application of a graphene oxide/partially reduced graphene oxide composite film |
| abstract |
The present invention relates to the preparation and application of a graphene oxide/partially reduced graphene oxide composite film, comprising the following steps: (1) adding a reducing agent to an aqueous graphene oxide solution to carry out a partial reduction reaction to obtain a partially reduced graphene oxide aqueous solution (2) the partially reduced graphene oxide aqueous solution and the graphene oxide aqueous solution are mixed to obtain a mixed solution; (3) the mixed solution is covered on the microfiltration membrane surface by vacuum filtration, and then dried to obtain a composite membrane. The preparation method of the invention is simple, efficient and low in cost, the prepared membrane is relatively stable in water, the layer spacing is adjustable, and the prepared membrane is used for dye separation and has excellent comprehensive performance. |
