▎ 摘　　要

NOVELTY - The reactor (400) has a reactor case having a first end (404) and a second end. A first ultrasound horn or array of ultrasound imparting devices are mounted at first end of reactor case and configured to impart ultrasound energy into reactor case. The inlet ports (402) are mounted above the first ultrasound horn or array (434) and configured to direct the fluid into the reactor case so that the fluid rises from the inlet ports toward the second end, the inlet ports are tangentially oriented with respect to an inner surface of the reactor case so that the fluid directed into the reactor case follows a vertical path as the fluid rises toward the second end. An outlet is configured to receive and pass the fluid out of the reactor case. An exfoliation zone (432) is provided between the inlet ports and the first ultrasound horn or array and is configured for receiving a graphite material to enable first ultrasound horn or array to impart ultrasound energy to graphite material. USE - Vortex reactor for manufacturing graphene material product. ADVANTAGE - The graphene materials are manufactured by utilizing the vortex reactors to control fluid dynamics and provide desired processing conditions to enable effective formation of the graphene materials. DETAILED DESCRIPTION - The reactor has an outlet pipe which is extended upwards from the first end to a position within the reactor case between the first end and the second end. A guide cone is coupled to the outlet pipe at an upper end of the outlet pipe. The fluid is advanced into the reactor case through the inlet ports which causes the fluid to flow in an outer vortex along an inner surface of the reactor case along distance toward the second end before the fluid reverses direction to flow into the guide cone and down the outlet pipe. The outlet pipe and the guide cone are aligned with a longitudinal axis of the reactor case. The injectors are configured to deliver a polymerizing agent or additive into the reactor case at a region where the fluid crests over the guide cone to reverse direction and pass down the outlet pipe. A second ultrasound horn or array of ultrasound imparting devices is mounted at the second end and extending toward the guide cone. The outlet is mounted at the second end. The reactor case has a cylindrical shape. The reactor case has a conical shape. The conical shape is provided with a narrower diameter at the second end than at the first end. The inlet ports are oriented to be transverse to a longitudinal axis of the reactor. INDEPENDENT CLAIMS are included for the following: (1) a method for manufacturing graphene sheet material involves providing a vortex reactor. The fluid mixture is directed into the vortex reactor so that the fluid mixture follows the vertical path through the vortex reactor. The fluid mixture is provided with two immiscible fluids. The vertical path of the fluid mixture aiding in separating the two immiscible fluids is provided to form an interface between the two immiscible fluids. The graphite material is provided within the vortex reactor. The ultrasound energy is imparted to the graphite material sufficient to generate graphene flakes. The graphene flakes aggregating at the interface is provided between the two immiscible fluids to form a graphene sheet material. The graphene sheet material has a tubular shape. The two immiscible fluids is water or is water based. The two immiscible fluids is an alkane. The alkane is heptane. The graphene sheet material is provided with an average thickness of five carbon atoms or less. The graphene sheet material is processed by cutting the sheet to form a thread, string, or ribbon graphene material. The main reactor is operated in a continuous mode by continuously extracting formed graphene sheet materials. The vortex reactor is operated in a batch or semi-batch mode by fully forming each graphene sheet within the reactor prior to ejecting the formed graphene sheet from the reactor; and (2) a method for manufacturing a graphene-enhanced composite material, involves directing a fluid mixture into the vortex reactor so that the fluid mixture follows an outer vertical path upwards through the vortex reactor to an apex and then the direction is reversed to pass downward through an outlet pipe. The fluid mixture is provided with two immiscible fluids and graphene flakes, one of the fluids is polymerizable. The ultrasound energy is imparted to the fluid mixture and graphene flakes are formed at the apex to form an emulsion. The graphene flakes aggregating at the interfacial regions are set between the two immiscible fluids of the emulsion. A polymerizing agent is injected into emulsion at the apex. The polymerizable fluid is allowed to polymerize, and the portion of graphene is trapped to form a graphene-enhanced composite material. A graphite material is provided within the vortex reactor and imparting ultrasound energy to graphite material to form the graphene flakes. The emulsion is passed to the molds to carry out the polymerization. The polymerizable fluid includes styrene.
