Abstract: Provided is a conical nano-carbon material functionalized needle tip, formed by assembling a nano-carbon material with a material of a needle tip by means of a covalent bond; and the material of the needle tip is a metal selected from one or more of tungsten, iron, cobalt, nickel and titanium. Further provided is a method for preparing the conical nano-carbon material functionalized needle tip. The conical nano-material functionalized needle tip has an outstanding interface formed by metal-carbide covalent bonds, and the orientation of the conical nano-material is matched with the axial direction of the metal needle tip (illustrated in FIG. 6). The proposed preparation method affords a robust interface and avoids the potential pollution to the nano-material caused during the deposition of fixing materials, such as carbon or platinum or the like, in other preparation methods.
