Single-layer graphene dispersion (PVPdispersion)

Overview
This product is an aqueous dispersion of high-quality single-layer reduced graphene oxide (rGO) stabilized with polyvinylpyrrolidone (PVP). The dispersion leverages graphene’s exceptional two-dimensional structure—comprising sp²-hybridized carbon atoms arranged in a hexagonal lattice with a C–C bond length of 0.142 nm and a monolayer thickness of 0.35 nm—to deliver outstanding electrical, thermal, and mechanical properties. PVP serves as a stabilizer, preventing aggregation and ensuring homogeneous dispersion for easy integration into various applications.
