Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms with sp² hybrid orbitals
Schematic diagram of graphene forming fullerenes, carbon nanotubes and graphite
Graphene oxide (graphene oxide) is an oxide of graphene, which is generally obtained by oxidation of graphite by strong acid

➤Analysis and detection applications
The Shanghai Institute of Applied Physics, Chinese Academy of Sciences found that the application of graphene oxide in PCR technology can significantly improve the specificity, sensitivity and amplification yield of PCR, and can eliminate primer dimers formed during amplification, and the optimization range is wide.
➤Biomedical applications
The high specific surface area and wide range of conjugated structure of graphene oxide make it have a certain potential application value on the support surface
➤Polymer composite materials
Graphene oxide can be processed in solution after functionalization, which is very suitable for the preparation of high-performance polymer composites
➤Optoelectronic related applications
The pure conductive polymer has poor stability in charge-discharge cycles, and the conductive synergy of the conjugated structure of graphene oxide and the conductive polymer can enhance the conductivity of the matrix and at the same time achieve structural enhancement
➤ Thermal application
The higher thermal conductivity and larger specific surface area undoubtedly lay the foundation for its use as a thermally conductive material.

Due to the high viscosity of graphene oxide, it is difficult to directly coat, and it needs to be dispersed to facilitate subsequent further processing.
The laser particle size analyzer report shows that the particle size of graphene oxide dispersed by ATS nano disperser is significantly reduced, D50 drops to 11.
