In the process of graphene industrialization, the thickness control accuracy directly determines the performance ceiling of the material. The fourth-generation ultra-high pressure micro-jet homogenization system independently developed by our company successfully achieves stable control of the thickness of single-layer graphene in the range of 2.66±0.15 nanometers through the construction of an ultra-high dynamic pressure field of 380 MPa. This technological breakthrough reduces the fluctuation rate of the number of graphene layers to less than 5%, providing a physical method solution for the large-scale preparation of high-quality graphene.
The equipment adopts multi-stage pressure adaptive adjustment technology to break through the process limitations of traditional chemical stripping method:
● Dynamic vortex control: Through micron-level flow channel design, directional dissociation of graphene sheets is achieved
● Pressure gradient compensation: Five-stage booster module ensures linear transmission of jet energy
● Intelligent monitoring system: Embedded spectrometer monitors the thickness distribution of sheets in real time
