Mass Production and Application Exploration of Nano Graphene Oxide (nGO)

Through optical defect engineering and oxidative degradation, conventional micron-sized graphene oxide is fragmented into nano-sized graphene oxide (nGO), with a lateral dimension of 20–60 nm and abundant carboxyl groups on the sheet edges. A production line with an annual output of 0.5 tons of powder has been established. The product exhibits excellent stability and high resistance to reduction. It is water-soluble, and can be modified to dissolve in various solvents including toluene, chloroform and NMP, forming stable solutions. This nGO product is amenable to a wide range of chemical reactions, and holds great promise for broad applications in the design and synthesis of novel polymers, plastic modification, and various electronic materials.
