NOVELTY - Producing a carbonized material, comprises applying a beam of electromagnetic radiation from a laser source to a polymeric substrate, varying the position of the beam to traverse over at least a portion of a surface of the polymeric substrate in a predetermined pattern, and controlling a fluence of the beam and speed of movement of the beam traversing over the portion of the surface of the polymeric substrate as a function of position on the surface to at least one predefined level of fluence and speed of movement of the beam to control at least one property of the produced carbonized material. USE - The method is useful for producing a carbonized material. ADVANTAGE - The method produced carbonized material which is rich in nanostructured graphene domains. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a system for producing a carbonized material, comprising a laser source configured to apply a beam of electromagnetic radiation from the laser source to a polymeric substrate, and a control system configured to vary the position of the beam to traverse over at least a portion of a surface of the polymeric substrate in a predetermined pattern and to control a fluence of the beam and speed of movement of the beam traversing over the portion of the surface of the polymeric substrate as a function of position on the surface to predefined levels of fluence and speed of movement of the beam to control at least one property of the produced carbonized material; (2) a composition comprising a carbonized material formed by a process comprising applying a beam of electromagnetic radiation from a laser source to a polymeric substrate, varying the position of the beam to traverse over at least a portion of a surface of the polymeric substrate in a predetermined pattern, and controlling a fluence of the beam and speed of movement of the beam traversing over the at least a portion of the surface of the polymeric substrate as a function of position on the surface to predefined levels of fluence and speed of movement of the beam to control at least one property of the carbonized material; and (3) a composition comprising a substrate including a path of laser-carbonized material, where the path comprises a gradient in at least one property of the carbonized material along the path.
