| titleOfInvention | Carbon nano-tube with fluorine-containing surface and preparation method thereof |
| abstract | The invention discloses a carbon nano-tube with a fluorine-containing surface, wherein the surface of the carbon nano-tube is of a carbon-fluorine covalent bond structure, the content of fluorine in the surface is 4-14%, and the decrease rate of the content of the fluorine is smaller than 5% after a produced fluorocarbon nano-tube is treated for 1 hour under a vacuum condition at 350 DEG C. The preparation method of the carbon nano-tube comprises the following steps of: firstly treating the carbon nano-tube by utilizing strong acid, secondly placing the carbon nano-tube in a vacuum reactor, charging fluorine/inert gas mixture with fluorine partial pressure of 10-100KPa in nitrogen atmosphere under room temperature to react for 0.5-4 hours at 150-300 DEG C, and cooling down to be the room temperature to obtain the carbon nano-tube. The fluorocarbon nano-tube prepared by the preparation method disclosed by the invention has the advantages of high fluorine content, low reaction temperature, high safety, energy conservation, and simple process, a fluorine-containing group of the surface of the treated prepared fluorocarbon nano-tube has good heat resistance and lower cost, and the fluorocarbon nano-tube is suitable for large-batch production and has stronger application prospect. |
