Grapheneoxid also exhibits excellent physical, chemical, and electrical properties. The graphene oxide can also be controlled due to the coexistence with various oxygen-containing groups on the base, edges, and graphene sheet frame. This allows for the control of its conductivity, band gap, and type. There are many uses for this material. Grapheneoxid is a new carbon material. It exhibits excellent properties with high specific surface areas and numerous functional groups. The wide variety of applications for grapheneoxid composite materials (including polymer composites and inorganic compounds materials) has led to the development of a new research focus on the surface modification.
In 2016, Karteri et al. In 2016, Karteri and colleagues studied organic thin-film transistors with SiO2/GO insulating layers, as well as their photoresponse characteristics devices. The characteristics of the transistor were also improved by adding GO to the insulating layers.
2 solar cells
Use GO to replace PEDOT:PSS in hole transport layers for polymer solar cell and achieve the same photoelectric conversion efficiency. Study of the effect of different thicknesses GO layers on polymer-solar cells has been done. The highest photoelectric conversion efficiency can be achieved when the GO film thickness reaches 2 nm.
3 Flexible Sensor
Because GO has many hydrophilic functional classes, it can be easily modified. It is ideal for flexible sensors because of its high specific surface area, good dispersion and high humidity sensitivity.
4 Biological considerations
GO is a unique combination of electronic and mechanical properties that has been used in many areas, including biotechnology, biomedical and nanomedicine, cancer therapy, tissue engineering and drug release. GO’s specific surface area is larger than other planar or spherical nanomaterials. It can also be easily modified and has a high biocompatibility. GO and alkene derivatives will have corresponding biological effects due to their surface charges, sizes, lateral dimensions, and surface chemistry. Further research is needed to determine GO’s biosafety. Material science will enable us to use low toxicity materials and better biocompatibility to modify GO. We can prepare GO with stable and clear properties, non-toxic, and non-toxic so that it can serve as a safe and efficient medical material.
