Polymer layered material graphene layers membrane production

by:Kolysen     2021-01-17
Because of the flat structure, graphene has been widely used in the manufacture of a polymer layered composite materials. By alternate deposition under electrostatic interactions GO of negatively charged and positively charged PANI preparation of PANI/graphene layers membrane, and then use hydroiodic acid reductive its GO components. PANI and GO with the thickness of single layer is estimated to be 1 respectively. 6 and 1. 32nm。 Monolayer forms by the concentration of the PANI and GO to control during assembly. PANI nanofibers and chemical transformation of graphene is made of layered composite membrane, PANI nanofibers sandwiched between the graphene layer. The composite membrane mechanical stability and high flexibility, thus can be bent into large Angle or shape for various structure is needed. Graphene can be formed by vacuum infiltration of graphene suspension with graphene as a structural unit of layered structure. Then, by using the layered graphene film as electrode in the dipping in monomer solution, the PANI can be aggregated to graphene.
