摘要： 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. In some embodiments LEST graphene has been used to prepare high-performance electrodes for triboelectric nanogenerators and supercapacitors. The resulting turbostratic graphene and graphene-based nanohybrids can be used, inter alia, as electrodes in energy conversion and storage devices, in flexible electronic devices, sensors, filters, photocatalytic reactors, etc.

摘要： The invention relates to a method of patterning a substrate with graphene-based or other electroactive-material-based solution that includes solid-phase particles as hard templates, reducing the solution, and processing the reduced solution to expose the particles. The exposed hard template particles are removed to leave a three-dimensional (3D) porous architecture that can be beneficially used for a variety of applications, including but not limited to bio sensors and supercapacitors. In one example, the exposure is by etching with a CO2 laser. The method can be practiced with scalable MEMS fabrication technologies.
