Title: METHOD AND SYSTEM FOR PRODUCING POLYMER/GRAPHENE OXIDE NANOCOMPOSITES REDUCED BY IN SITU REDUCTION OF GRAPHENE OXIDE
Abstract:
Method and device for reducing a component composed of at least one graphene oxide and a matrix consisting of at least one polymer, characterised in that the method comprises at least the following steps: a) introducing a mixture of polymer(s) and graphene oxide GO into a reactor (10) subject to a value of temperature T and a value of pressure P suitable for placing a fluid under supercritical or subcritical conditions for a given period, the temperature T being suitable for not degrading the polymer, and b) cooling the reactor (10) and removing the obtained product R consisting of reduced polymer(s) and graphene oxide rGO.
