The utility model is characterized in that the anodes and the cathodes of two electrodes fixed to a sealing plug of a sealing quartz reaction tube are arranged in the quartz reaction tube; the ends of the anodes of the electrodes are made into a tip shape, and the ends of the cathodes of the electrodes are made into a platform shape the quartz reaction tube is provided with an air inlet nozzle and an air outlet nozzle. The utility model adopts the mode of plasma polymerization and creates a nanometer carbon tube with the inner diameters being 4 to 6 nm and the outer diameters being 22 to 30 nm. Needed energy does not need to be cracked by high temperature, which causes the theory conversion degree to achieve 100%. The utility model provides a new way for preparing nanometer carbon tubes.
Description
The utility model relates to preparation CNT (carbon nano-tube) device, and especially a kind of plasma body prepares the CNT (carbon nano-tube) device.
Nanotechnology is with a wide range of applications as current a kind of new high-tech material.But the technology of existing preparation CNT (carbon nano-tube) generally adopts arc discharge, heat and catalytic decomposition, chemical vapour desposition method to produce, and needs a large amount of energy and heat, the cost height.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, the using plasma polymerization methods and need not any catalyzer situation under the device of preparation CNT (carbon nano-tube).
The purpose of this utility model is achieved in that
The positive and negative electrode that is packed in two electrodes on the sealing crystal reaction tube sealing plug places in the crystal reaction tube, the electrode anode end is made as pointed, the negative pole end is made as platform-like, on crystal reaction tube, be shaped on an admission piece and an outlet nozzle, admission piece is at the crystal reaction tube position of electrode anode, and outlet nozzle is built in electrode negative pole crystal reaction tube position.
Electrode anode tip diameter is 0.2-0.6mm, and electrode negative pole platform diameter is 4-12mm, and land thickness is 2mm, and the quartz reaction bore is 6-15mm; The gas that the made admission piece of crystal reaction tube feeds is the gas mixture of hydrogen and acetylene gas; The distance of electrode positive and negative electrode end is 5-25mm, and electrode is made by isometrical round brass rod or stainless steel bar.
Advantage of the present utility model and positively effect are:
The using plasma polymerization methods; at normal temperatures; produce the CNT (carbon nano-tube) of internal diameter 4-6nm, external diameter 22-30nm by corona discharge; do not need to come cracking institute energy requirement with high temperature; thereby exempted to environment and conducted heat and save energy; simultaneously also exempted the fuel that is used to provide reaction heat, made theoretical yield reach 100%, very favourable to environment protection.And it is structural good that the CNT (carbon nano-tube) of normal temperature preparation has, and the dispersity height does not use any catalyzer, for the preparation CNT (carbon nano-tube) provides a new road.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:
Optimum mode of operation of the present utility model is:
Battery lead rod footpath: 3mm;
Electrode anode tip diameter: 0.3mm;
Electrode negative pole platform diameter: 5mm;
Electrode negative pole land thickness: 1.5mm;
Electrode anode end and electrode anode end distance: 8mm;
