  • Publication number: 20240253993
    Abstract: Disclosed herein methods for the Laser-assisted Explosion Synthesis and simultaneous Transfer (LEST) of few-layer turbostratic graphene and graphene-based nanohybrids onto any substrate. Industrially scalable laser-assisted methods of fabricating turbostratic graphene by irradiating carbon-containing compounds (e.g. polymers, organic compounds, biomass-derived products, graphitic materials and their combinations). Laser-assisted methods for preparation of turbostratic graphene/inorganic nanoparticles hybrids. The disclosed processes are versatile as they operate at ambient (atmospheric) environment and through single lasing irradiation at the cm-scale spot size. LEST is capable of producing, and simultaneously transferring, turbostratic graphene on any substrate, such as polymer, glass, carbon paper, metal, ceramic, and so on, avoiding intermediate transfer steps and chemical treatment.
