▎ 摘  要

NOVELTY - A carbon material comprises several carbon aggregates, each comprising several carbon nanoparticles, each comprising graphene with no seed particles. The graphene comprises 15 or less layers. The carbon aggregates have median size of 1-50 mu m, surface area of 50 m2/g or less when measured with Brunauer-Emmett-Teller method with nitrogen as adsorbate and electroconductivity of 500 S/m or more. USE - Carbon material is used in electroconductive ink, tire additive and battery electrode (all claimed). Can also be used in lubricant formulations for high-stress, high-speed, high-temperature environment, high-thermal conductivity and anti-stiction lubricant applications, filtration and separation application for chemical filters, water filtration, desalination, gas separation, oxidation barrier, impermeable membranes, non-reactive filters and carbon sequential material, transportation and industrial applications for rubber additives, additives for couplings, mounts, elastomeric o-rings, hoses, sealants and epoxies, metamaterial formulations for the particles or aggregates decorated with nickel, cobalt or iron nanowires, carbon dielectric layered materials, and interface materials with functionalized surfaces. Electronic ink formulations for transparent conductive inks, 3 dimensional printed circuits and boards, resistivity ink, dielectric ink, flexible electronics, piezoelectrics, antennas, electrochromic devices, triboelectric devices, microwave equipment, system inks, and identification systems, other inks for cosmetics, and 3D printed structural inks, coatings for anti-corrosion, super hydrophobic, room heating, de-icing, cooling, electro-static discharge, radio frequency shielding, radio frequency absorbing, and fabric and textile coatings, capacitor material formulation for super capacitor additives, high surface area carbon, high purity carbon, high surface area high purity carbon, and separators, sensors and solid state electronics application for chemical, humidity, touch, light, transistors, diodes, and integrated devices, composite material formulation for cement, steel, aluminum, plastics, and carbon fiber, energy applications for hydrogen storage, anode and cathode composites, batteries, fuel cell electrodes, capacitors and capacitor/battery hybrids, in-vivo biomedical applications for tissue engineering, drug delivery, metal delivery, bio-degradable nanowire for neuro regeneration, and skin electrodes and other medical devices. ADVANTAGE - The carbon material can be produced quickly and economically with improved microwave reactors. The mechanical processing reduces the particle size without damaging the carbon allotropes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for electroconductive ink.
