Studying the behavior of reduced graphene oxide particles at the water-air interface

Reduced graphene oxide (RGO) particles were obtained from natural and artificial graphite using chemical reduction. The particles were placed on an aqueous subphase surface in a Langmuir trough from suspensions in carbon tetrachloride. Compression isotherms of layers of RGO particles were obtained f...

Description
Summary:Reduced graphene oxide (RGO) particles were obtained from natural and artificial graphite using chemical reduction. The particles were placed on an aqueous subphase surface in a Langmuir trough from suspensions in carbon tetrachloride. Compression isotherms of layers of RGO particles were obtained for different amounts of the substance deposited on the subphase. Layers on the aqueous subphase surface were studied using a Brewster microscope and measurements of the surface potential. Comparison of the obtained data made it possible to determine the stage of the formation of a continuous RGO layer.
