Laser-assisted synthesis of graphene from pitch

Abstract

A method for synthesizing graphene includes depositing pitch on a substrate to provide a pitch sample, and pyrolyzing at least a portion of the pitch sample with a laser, thereby forming graphene. A method for upgrading pitch includes providing a pitch sample under vacuum, and irradiating the pitch with a laser to form an upgraded pitch product. A system for synthesizing graphene includes a pitch deposition system configured to deposit pitch on a substrate to form a deposited pitch sample, and a laser irradiation system. The laser irradiation system includes a laser comprising an outlet for a beam of light, and a substrate holding area in line with the outlet of the laser. The laser irradiation system is capable of transforming at least a portion of the deposited pitch sample to form graphene.
