Application
Graphene Nanoplatelets, measuring 6-8nm in thickness and 25μm in width, serve as a versatile and advanced material with a diverse range of applications. These nanoplatelets are integral to the development of anti-corrosion coatings, providing enhanced durability and protection. They are also critical in anti-static packaging solutions and are used extensively in cement composites to improve material properties. In the field of electronics, the unique structure of graphene contributes to creating highly efficient composites. This material's few-layer structure, comprising ultra-thin carbon atom layers in a hexagonal honeycomb lattice, offers extraordinary electronic, optical, and mechanical properties. These properties open up applications in energy-related technologies, such as photovoltaic devices, batteries, and sensors. Additionally, their flexibility and conductivity are pivotal in the advancement of flexible electronics, photodetectors, and biomedical applications, including drug delivery, bio-imaging, and tissue engineering.
