技術說明

本發明係有關一種具有複數接點之奈米碳管（CNTs）之製造方法， 至少包含：在化學氣相沉積系統中，提供至少一基材；金屬粉末； 以及含碳反應氣體，於高溫環境下進行反應，以在前述基材上形成 具有複數接點之奈米碳管，其中前述複數接點之奈米碳管係為二維 （two-dimension）及/或三維（three-dimension）結構且具有相似 直徑之網狀結構（webs）。 Branching structure in carbon nanotubes (CNT) are of great importance in developing novel CNT-based mechanical or electrical applications. For this purpose, CNTs exhibiting two-dimensional and three-dimensional junctions are being sought. Among them, only two-dimensional branching structures of Y-junction and T-junction CNT have been synthesized. In this letter, we have successfully grown new CNT branching webs having two-dimensional H- junction and multiple Y-junctions, and three-dimensional multiple junctions using a thermal chemical vapor deposition (CVD) method without the use of a template. The result not only shows the possibility of creating three-dimensional complex CNT structures but also provides the nanotechnology community with new base materials for the development of nano-scale mechanical or electrical devices.
