Abstract
The invention relates to a manufacturing method of a carbon nano tube modified fiber line and a manufacturing device thereof. The manufacturing method is characterized by comprising the following steps: dissolving the carbon nano tubes in an organic solvent, and carrying out ultrasonic dispersion to prepare a carbon nano tube suspension; soaking the fiber line in the suspension, and electrifying two conical poles to form a non-uniform electric field; and lifting the fiber line out of the liquid level of the suspension to obtain the carbon nano tube modified fiber line. Compared with the prior art, the invention has the characteristics that by using the non-uniform electric field, the carbon nano tubes in an electrostatic induction state quickly and effectively enter the capillary tubes of natural fiber lines in the strongest part of the electric field, and simultaneously are adsorbed on the external surfaces of the natural fiber lines, thus the carbon nano tube modified fiber lines can be manufactured in one process, and the work efficiency is higher.
Description
Affiliated technical field
The invention belongs to the processing technique field of CNT, particularly a kind of carbon nano tube modified fiber line.
Background technology
At present, electronic textile becomes a reality.This material can be applicable to biomedicine, environment and food security field in the future, for example, and monitoring of diseases and people's vital sign; As biology sensor testing environment and food security pollutant.But present electronic textile is all pliable and tough inadequately, too firm, and has been covered with electric wire and sensor, uses very trouble, also is unsuitable for large-scale production simultaneously.Univ Michigan-Ann Arbor USA professor Nicholas Oleg Kotov and the professor of Southern Yangtze University petty official the people such as are transmitted and have been reported a kind of new method of making electronic fiber: be coated with CNT and electrolyte on the common cotton fiber.The researcher is flooded in the middle of common cotton thread is put into carbon nano-tube solution repeatedly, makes its drying again.So repeatedly several times after, this cotton fiber by carbon nano-tube modification has just had electric conductivity, and has stronger durability and pliability, also approaches common fabric on material more.But such manufacture method work efficiency is too low.
Summary of the invention
In order to solve the too low deficiency of above-mentioned prior art work efficiency, the manufacture method and the manufacturing installation that the purpose of this invention is to provide a kind of like this carbon nano tube modified fiber line: under the effect of non-uniform electric field, CNT enters the capillary of filamental thread rapidly and is adsorbed on the outer surface of filamental thread, the realization CNT combines with filamental thread, makes conduction and pliable and tough carbon nano tube modified fiber line.
The present invention realizes like this:
A kind of manufacturing installation of carbon nano tube modified fiber line, it mainly comprises: container, sub-thread or multiply filamental thread, guide roller and filter plate, described container is built-in with carbon nano tube suspension, the external taper the two poles of the earth that the formation non-uniform electric field is arranged of container; Described filamental thread is around on the guide roller, places the carbon nano tube suspension in the described container, and by corresponding aperture on the described filter plate; Described filamental thread is parallel to be placed on the central axis that taper the two poles of the earth form.
A kind of manufacture method of carbon nano tube modified fiber line, it comprises the steps:
1) CNT is dissolved in the organic solvent, and carries out ultrasonic dispersion, make carbon nano tube suspension;
2) fill outside the container of suspension, the energising of taper the two poles of the earth forms non-uniform electric field, and dry filamental thread enters suspension evenly, moves in suspension evenly;
3) at the uniform velocity lift filamental thread and leave the suspension liquid level, and by corresponding aperture on the filter plate, elimination is adsorbed on the outer unnecessary CNT of filamental thread;
4) described filamental thread promptly obtains carbon nano tube modified fiber line through the immersion of electrolyte solution.
Described filamental thread is silk fiber line or the cotton fiber line in the natural fabric line.
Described CNT is Single Walled Carbon Nanotube, multi-walled carbon nano-tubes or CNT tube bank.
The present invention's characteristics compared with prior art are:
1), the present invention utilizes non-uniform electric field, impel the CNT that is in the electrostatic induction state fast and effeciently to enter to be arranged in the capillary of the strength of electric field filamental thread, also be adsorbed on the outer surface of filamental thread simultaneously, so can in an operation, finish the work of making carbon nano tube modified fiber line, have higher work efficiency.
2), under the non-uniform electric field effect, in the filamental thread capillary, and the heteropole that is adsorbed between the CNT on the filamental thread outer surface closely links to each other, so modified fiber line of the present invention has better electric conductivity.
3), owing in the filamental thread capillary, be full of CNT, and closely link to each other between the CNT, so modified fiber line of the present invention has tensile strength and the toughness higher than prior art, the shielding of can taking exercises, such as making the athletic legging of football, just can the condition of the injury on that green field not continuous.
Description of drawings
Accompanying drawing is the cross-sectional schematic of manufacturing installation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
Manufacturing installation of the present invention mainly comprises: container 1, sub-thread or multiply filamental thread 2, guide roller 3 and filter plate 6, and described container 1 is built-in with carbon nano tube suspension 4, container 1 external taper the two poles of the earth 5 that the formation non-uniform electric field is arranged; Described filamental thread 2 is around on the guide roller 3, places the carbon nano tube suspension 4 in the described container 1, and by corresponding aperture on the described filter plate 6; Described filamental thread 2 is parallel to be placed on the central axis that taper the two poles of the earth 5 form.
CNT is dissolved in the organic solvent, and solvent is included as ethanol, acetone, n-hexane, isopropyl alcohol, dimethyl formamide or 1,2-dichloroethanes etc.Before making filamental thread of the present invention, solution need pass through long-time ultrasonic dispersion, makes the suspension 4 that even carbon nanotube is disperseed.Used CNT is Single Walled Carbon Nanotube, multi-walled carbon nano-tubes or CNT tube bank.
Because the filamental thread surface of above-mentioned proposition suspension liquid level can adsorbed some too many CNTs usually, can be by corresponding aperture elimination on the filter plate 6.The diameter of this corresponding aperture can have enough CNT envelopes with the surface that guarantees above-mentioned filamental thread selectively greater than the diameter of above-mentioned filamental thread, guarantees that it has good electrical conductivity.
In order to guarantee to make in the future textiles wearing comfortableness later on, above-mentioned filamental thread 2 is preferably the natural fabric line, particularly silk fiber line or cotton fiber line, and the silk fiber line can be thinner than cotton fiber line, is more suitable for making thinner carbon nano tube modified fiber line.
Because electrolyte can play the CNT stable effect in filamental thread that guarantees; In addition, the hydrophily of electrolyte also can guarantee to make in the future textiles wearing comfortableness later on, so above-mentioned filamental thread can be through soaking, to obtain the adding of electrolyte in electrolyte solution.
Through after the above-mentioned steps, promptly obtain carbon nano tube modified fiber line.
