Embodiment
Please refer to Fig. 1, the utility model provides a carbon nano-tube compound wire 100, comprises the metal level 12 that a carbon nano-tube single thread 10 and is coated on described carbon nano-tube single thread 10 outer surface.
Described carbon nano-tube single thread 10 is made up of the axial-rotation twisting of multiple carbon nano-tube along this carbon nano-tube single thread 10.Described carbon nano-tube single thread 10 can obtain a carbon nano tube line by pulling from a carbon nano pipe array, and is relatively rotarily formed at the two ends of described carbon nano tube line.The two ends of described carbon nano tube line can be turned round along clockwise direction, thus form S sth. made by twisting; The two ends of described carbon nano tube line can be turned round in the counterclockwise direction, thus form Z sth. made by twisting.Because the carbon nano-tube directly pulled from carbon nano pipe array in the carbon nano tube line that obtains extends along the axis of described carbon nano tube line substantially, and joined end to end by Van der Waals force at the axial direction of described carbon nano tube line.Therefore, by in relatively pivotal for the two ends of described carbon nano tube line process, carbon nano-tube in this carbon nano tube line along the axial direction helical arrangement of carbon nano tube line, and can be joined end to end by Van der Waals force at bearing of trend, and then forms described carbon nano-tube single thread 10.In addition, by in relatively pivotal for the two ends of described carbon nano tube line process, spacing between carbon nano-tube radially adjacent in described carbon nano tube line can diminish, contact area increases, thus the Van der Waals force between carbon nano-tube radially adjacent in described carbon nano-tube single thread 10 is significantly increased, and be closely connected.Spacing between carbon nano-tube radially adjacent in described carbon nano-tube single thread 10 is less than or equal to 10 nanometers.Preferably, the spacing between radially adjacent in described carbon nano-tube single thread 10 carbon nano-tube is less than or equal to 5 nanometers.More preferably, the spacing between radially adjacent in described carbon nano-tube single thread 10 carbon nano-tube is less than or equal to 1 nanometer.Because the spacing between carbon nano-tube radially adjacent in described carbon nano-tube single thread 10 is less and be closely connected by Van der Waals force, therefore described carbon nano-tube single thread 10 has the smooth and surface texture of densification.
The diameter of described carbon nano-tube single thread 10 is 1 micron to 30 microns.The twist of described carbon nano-tube single thread 10 is 10 turns/centimetre to 300 turns/centimetre.The described twist refers to the pivotal number of turns of unit length carbon nano tube line.When the diameter of described carbon nano-tube single thread 10 is determined, the suitable twist can make described carbon nano-tube single thread 10 have good mechanical performance.This is because, along with the increase of the twist, the reduction of spacing between carbon nano-tube radially adjacent in described carbon nano-tube single thread 10, thus the active force between radially adjacent carbon nano-tube can be strengthened; But when the twist is excessive, the active force between carbon nano-tube in axial direction adjacent in described carbon nano-tube single thread 10 can reduce on the contrary.When the diameter of described carbon nano-tube single thread 10 is less than 10 microns, the twist of described carbon nano-tube single thread 10 is preferably 250 turns/centimetre to 300 turns/centimetre; And when the diameter of described carbon nano-tube single thread 10 is 10 microns to 20 microns, the twist of described carbon nano-tube single thread 10 is preferably 200 turns/centimetre to 250 turns/centimetre; And when the diameter of described carbon nano-tube single thread 10 is 25 microns to 30 microns, the twist of described carbon nano-tube single thread 10 is preferably 100 turns/centimetre to 150 turns/centimetre.The mechanical strength of described carbon nano-tube single thread 10 can reach the 5-10 of the mechanical strength of the gold thread of same diameter doubly.In the present embodiment, the diameter of described carbon nano-tube single thread 10 is about 25 microns, and its twist is about 100 turns/centimetre.
Because described carbon nano-tube single thread 10 has the smooth and surface texture of densification, therefore described metal level 12 can form good combination, difficult drop-off with described carbon nano-tube single thread 10.Described metal level 12 is coated on the outer surface of described carbon nano-tube single thread 10 uniformly, and its thickness is 1 micron to 5 microns.When the thickness of described metal level 12 is 1 micron to 5 microns, the conductivity of described carbon nano-tube compound wire 100 can arrive more than 50% of the conductivity of metal in described metal level 12.When the thickness of described metal level 12 is too little, such as be less than 1 micron, the conductivity of described carbon nano-tube compound wire 100 can not be significantly improved on the one hand, on the other hand, this metal level 12 also can be made easily oxidized in use, reduce conductivity and the useful life of described carbon nano-tube compound wire 100 further.In addition, experiment proves when the thickness of described metal level 12 is greater than certain value, and be such as greater than 5 microns, the conductivity of described carbon nano-tube compound wire 100 not only can not significantly increase, and also additionally can increase the diameter of described carbon nano-tube compound wire 100.The material of described metal level 12 can be the good metal or alloy of the conductivity such as gold, silver, copper.In the present embodiment, described metal level 12 is about the copper of 5 microns for thickness, thus makes the conductivity of this carbon nano-tube compound wire 100 reach 4.39 × 10
7s/m is about 75% of the conductivity of metallic copper.Please refer to Fig. 2, in the present embodiment, the diameter of described carbon nano-tube compound wire 100 is about 35 microns, and its tensile stress can reach more than 900MPa, is about 9 times of gold thread under same diameter.In addition, from figure, 2 it can also be seen that the tensile strain rate of described carbon nano-tube compound wire 100 is about 3%.
Described metal level 12 can be formed at the outer surface of described carbon nano-tube single thread 10 by methods such as plating, chemical plating, evaporations, and then forms described carbon nano-tube compound wire 100.
The carbon nano-tube compound wire that the utility model provides by optimizing the diameter of described carbon nano-tube single thread and the thickness of the twist and described metal level simultaneously, thus makes described carbon nano-tube compound wire have good mechanics and mechanical performance simultaneously.Particularly, first, by optimizing the thickness of described metal level, thus described metal level can be made to have good antioxygenic property and durability; Secondly, because described metal level has larger thickness, therefore, in use, described metal level plays main electric action to described carbon nano-tube compound wire, namely, electric current conducts mainly through the top layer of carbon nano-tube compound wire, namely by metal layer conductive, is formed and similarly drives skin effect, therefore, the conductivity of described carbon nano-tube compound wire can be significantly improved; Finally, by optimizing diameter and the twist of described carbon nano-tube single thread, thus the mechanical performance of described carbon nano-tube compound wire can be significantly improved.In addition, described carbon nano-tube compound wire in use, even if described metal level is fused by high temperature, because carbon nano-tube has good heat resistance, described carbon nano-tube single thread also can not open circuit easily, thus described carbon nano-tube compound wire can also be made to keep channel status, and then improve the durability of described carbon nano-tube compound wire.
In addition, those skilled in the art can also do other change in the utility model spirit, and these changes done according to the utility model spirit all should be included in the utility model scope required for protection.
