In addition to planar graphene and powder graphene, there are also vertically standing graphene. Recently, the Hay Think team walked into SZYX Graphene Technology Corporation to learn about this new material. It is understood that compared with the former two, the detection sensitivity of the vertically standing graphene can be increased by a hundred times.
SZYX is the only national high-tech enterprise in China focusing on providing solutions for vertically standing graphene film materials and material applications.
Vertically standing graphene is a complex carbon nano-film material with a pore structure formed by overlapping a few layers of graphene groups with spatially folded and hierarchical structures. It is suitable as a high-sensitivity sensing material.
Compared with traditional planar graphene and powdered graphene, the vertically standing graphene is a three-dimensional structure with low resistance and good performance. The surface area is increased by more than a hundred times, and the detection sensitivity can be increased by a hundred times.
Vertically standing graphene, as a unique material of SZYX, has been accumulated for nearly ten years in material development and industrialization.
At present, SZYX has obtained more than 40 domestic and foreign invention patents, including core material patents for vertically standing graphene and core production equipment, technology, and material composite modification. It is actively promoting the establishment of corporate standards and national standards. In addition, SZYX has established a large-scale vertically standing graphene wafer chip production workshop, with an annual output of 80 million pieces of vertically standing graphene electrochemical test sensor chips, and more than 20 million pieces of flexible stretched vertically standing graphene electrodes.
Vertically standing graphene, as a sensor sensitive material, has the characteristics of simple device structure, stable and controllable performance, large range, high precision, etc. It is especially conducive to the secondary development of artificial crystal nanomaterials and sensing technology. If these characteristics are applied to underground safety sensors, it is expected to realize multi-parameter sensing, which may have the advantages of high accuracy, large range, and controllable cost, which is especially beneficial to the monitoring of different key parameters in the field of infrastructure security.
