Practical application is already imminentTargeting creation of new industriesIn actual fact, after Hata developed the super growth method, he says that he worried about where to place the research emphasis.“It was apparent that disciplines with infinite potential were unfolding right before my very eyes. However, I didn’t want the super growth method to be a flash in the pan boom: I wanted it to be prominent 10 or 20 years from now, and be a technology that would increasingly blossom.”Thereupon, Hata decided to aim for commercial-scale production of single-wall CNTs on an unprecedented scale. Working jointly with the chemical company Zeon Corp., development of a single-wall CNT commercial-scale production technology commenced. Besides creating a comprehensive vision for the commercial-scale production process, planning research, and setting milestones, Hata guided a synthesis group that included researchers from Zeon.He successfully guided the research elements one by one, including continuous synthesis, large surface area synthesis, development of a wet catalyst, and development of a metal substrate. A demonstration plant combining these technologies commenced operations in 2012 as an entity that could, for the first time in the world, manufacture single-wall CNTs in units of 100 g and moreover, supply them at a practical cost.“Currently we are transitioning to applications research, and having developed highly functional CNT-based parts through dispersion/processing/composite production technology, we are now carrying out application development that will lead to creation of industries. Gathering together all of the technologies developed to date, we have come up with a B2B flow between material manufacturers and application manufacturers.”The application scope of single-wall CNTs is diverse, spanning energy, environment, and IT (information technology). Concrete examples of practical applications underway include conductive rubber materials, carbon textiles, conductive plastics, strain gauges, and capacitors*3. AIST is targeting a cost of JPY10,000 per kilogram by 2020, and if commercial-scale production can be achieved through lowering costs, major innovation will surely occur in the industrial sector.At last, industrial-scale production of single-wall CNTs is set to be achieved in 2015.“Our objective is for single-wall carbon nanotubes to be utilized ‘here, there, and everywhere.’ Furthermore, I want to see my mother actually holding a product that contains CNTs when I return home. With this objective, I want to devote my career to CNT R&D.”Diverse application potential for carbon nanotubesCarbonnanotubesCare equipmentMultifunctionalinput interfacesLSI-viawiringSolar cell electrodesElectronic paperTouch panelsMemorywiringLithium batteryelectrodecomponentsFuel cellsystemsCapacitorsConductive plastic materialsHigh strengthcarbon prepregsBio-gas sensorsHuman bodymonitoringRobot skinMicro-condenserdevicesMicrowave shieldsCNT wireharnessesNext-generation carbon fiberHighelectricalconductivitysystemsHigh performancethermally-conductivematerialsOA equipment rollsLi ioncollectorsHighstrengthcarbon materialsShapepropertycontrolSemiconductor/metal separationUniformdispersionsFiber, sheet andmesh formsCNT textilesCNT-MEMSActuatorsCompositeformationBatteryelectrodesTransparentconductive filmsElectronic circuitcomponentsElectromagnetic waveabsorption materialsThin-filmtransistorsData tagsWireless power supply sheetsInfrared image sensorsCNTinkConductive rubber/filmsSensor materialsEnergy fieldHighly functional materials fieldElectronics fieldBatterycomponentsSource: AIST TODAY 2011-7(2011, NEDO)▲The thermal conductivity of rubber developed using CNTs is on par with that of titanium, yet is light, thin and flexible.
