Using of the chemography method for assessing the homogenizati on of graphene nanotubes in the aqueous environment

Abstract

The problem of effective homogenization of graphene nanotubes in an aqueous environment is considered. Usually, the high activity of nanotubes leads to the formation of various conglomerates in the solution, and with further application of the aqueous solution, such conglomerates can be transferred to the composite materials being created. Currently, there are no effective fast control tools, and therefore in engineering practice, various fairly complex methods that require specific equipment are often used. Chemography as a method of recording oxidative reactions with ultra-low concentrations of active substances can be successfully used as a means of quick and effective control of the homogeneity of graphene solutions (mainly water-based). Recommendations for the application of the method are given, models are proposed for determining the dispersion of the expected concentration on the controlled surface. A conclusion is made regarding the expediency of monitoring the state and activity of graphene nanotubes.
