Abstract:
본 발명은 탄소나노튜브를 이용하여 나노입자를 제조하는 방법 및 이 방법에 의하여 제조된 나노입자를 제공한다. 본 발명은 물리적으로 견고한 구조를 가지고 화학적으로 단단한 결합을 형성하고 있는 탄소나노튜브를 이용하여 금속, 고분자 및 세라믹 등의 분말 입자를 나노 크기로 분쇄하는 것을 특징으로 한다. 또한 이러한 방법을 통하여 제조된 나노입자는 크기가 작고 탄소나노튜브를 포함하고 있으므로 산화력이 좋은 금속에 이용할 경우 고체연료 및 화약 등 발화성이 필요한 응용분야에 적용할 수 있다. 또한, 탄소나노튜브는 기계적 특성과 전기전도도가 우수함으로 그와 관련한 제품에 적용할 수 있다.
Abstract:
A method of making a treating wash includes mixing brass granules with acetone, mixing carbon nanotube material, silver granules, iron pyrite granules and copper granules in the acetone brass mixture, and straining the liquid from the remaining solid material. Methods of treating materials such as brass granules, silver granules, iron pyrite granules, carbon nanotube material, and copper granules comprises washing the materials in the treating wash, followed by straining and drying the materials.
Abstract:
Gegenstand der Erfindung ist ein strangförmiger Materialverbund (21), der CNT-Garne (23) enthält, die in einer metallischen Matrix (25) eingelagert sind. Die Einlagerung in eine gemeinsame Matrix (25) hat den Vorteil, dass der Materialverbund eine verbesserte elektrische Leitfähigkeit aufweist. Dies liegt an der Möglichkeit, dass Elektronen von den CNT (23) in die Matrix (25) und wieder zurück wechseln können. Der strangförmige Materialverbund ist daher zum Einsatz als elektrischer Leiter geeignet. Weiterhin unter Schutz gestellt ist auch ein Verfahren zur Herstellung des strangförmigen Materialverbundes.
