Description
Technical field
The present invention relates to the manufacture method of conductive fiber for clothing and sensing electrode, be related specifically to a kind ofly can be used for electrocardiosignal, sensing electrode that electromyographic signal, EEG signals, breath signal collect and transmit, the electric conductivity in field such as intelligence wearing, intelligent textile, flexible electronic device etc., the adjustable pattern of pliability can manufacture and design arbitrarily and preparation method thereof.
Background technology
Since from Apple in 2007, (AppleInc.) issued first generation touch-screen mobile phone, people to the cognition of smart machine and demand more and more deep.Particularly with Apple in the extensive use of the intelligent watch AppleWatch that 2014 the issue New Generation of Intelligent Wearable hardware that is representative and universal, the concept that intelligence is dressed is rooted in the hearts of the people.But existing intelligence dress hardware often because its incomplete design or not easily dress and extensively denounced.Real wearable intelligent hardware should be never leave each other with human body just can accomplish Data acquisition and issuance timely, could meet the demand of people under the prerequisite of normal life not disturbing people.Therefore, only have and sensor in Intelligent hardware incorporated in clothing that people wear, just can realize such target.Although; the flexibility of similar wearable hardware and scalable electronics were subject to the extensive concern of researcher and achieved a series of application progress in recent years; as flexible touch screen display, bent and stretchable electronic element array, flexible pressure sensor and strain transducer (XuS.; ZhangY.; ChoJ.; etal.NatureCommun.2013,4,1543; LipomiDJ., VosgueritchianM., TeeB.C.K., etal.NatureNanotech.2011,6,788; YamadaT., HayamizuY., YamamotoY., etal.NatureNanotech.2011,6,296).The realization of these application devices often can need to use elastic electric conductor or specially designed electrode circuit connects to realize telescopic circuit.In order to realize these functions; the preparation method of usual flexible electrical conductors is mainly divided into three major types: the first directly fills dispersed electro-conductive filler in synthetic fiber process; as (SekitaniT. such as CNT, Graphene, conductive black, metal nano materials; NakajimaH.; MaedaH.; etal.NatureMater.2009,8,494; XuF., ZhuY.Adv.Mater.2012,24,5117; Chinese patent ZL201110237446.2; Chinese patent ZL201110441254.3), the shortcoming of this method is, textile fabric hardness can be caused when loading is large to become large, be unfavorable for elastic deformation, the fiber of particularly filling carbon black or CNT often color is restricted and affects it and use on a large scale; Second method is in three-dimensional porous conductive network, as foam-like Graphene, carbon nano pipe array, infiltrates liquid polymer and carries out being polymerized (ChenZ., RenW., GaoL., etal.NatureMater.2011,10,424; ShinM.K., OhJ., LimaM., etal.Adv.Mater.2010,22,2663), the elastic electric conductor that this method obtains is owing to needing the integrality ensureing three-dimensional conductive network, and limited degree of deformation is usually less; 3rd class methods are the structures of constructing the strain that can prestore in conductive material, as waveform (CaiL., LiJ., LuanP., etal.Adv.Func.Mater.2012,22,5238), this method is most widely used, but also there is complex process and usually can only keep high performance problem within the scope of prestrain.Other conductive fiber manufacturer rule comprises (1) and filament, microplate is woven in yarn in spinning process, but this method often makes conductive capability have a greatly reduced quality (Chinese patent ZL201110259232.5); (2) by conductive polymer fibers and common textile fibers blending; also have the conductive capability of same problem and conducting polymer self limited, simultaneously conductive polymer fibers add Costco Wholesale (the Chinese patent ZL200610032518.9 that membership increases fabric greatly; ZL201210044385.2).
Metal nanometer line, as a kind of one-dimensional nano structure material, formation conductive fiber material has advantageous advantage.From the people such as YounanXia (SunY., Yin, Y., Mayers since the synthesis of reported first nano-silver thread in 2002 of the georgia ,u.s.a Institute of Technology; B.T., Herricks, T.; Xia, Y.Chem.Mater.2002,14; 4736), people continue again the synthetic method having developed other metal nanometer lines multiple, comprising copper nano-wire (YeE.; ZhangS.-Y., LiuS., HanM.-Y.; Chem.Eur.J.2011,17,3074; ChangY., LyeM.L., ZengH.C.Langmuir, 2005,21,3746; KevinM., OngW.L., LeeG.H., HoG.W.Nanotechnology2011,22,235701; Chinese patent ZL201210082765.5), nanowires of gold (LuX., YavuzM.S., TuanH.-Y., KorgelB.A., XiaY., J.Am.Chem.Soc.2008,130,8900; Wang, C., HuY., LieberC.M., SunS., J.Am.Chem.Soc.2008,130,8902; HuoZ., TsungC., HuangW., ZhangX., YangP., NanoLett.2008,8,2041; Pazos-PerezN., BaranovD., IrsenS., HilgendorffM.; Liz-MarzanL.M., GiersigM., Langmuir2008,24; 9855), palladium nanometer wire (HuangX., ZhengN., J.Am.Chem.Soc.2009; 131,4602), alloy nano-wire (WangY.; WangQ., SunH., etal.; J.Am.Chem.Soc.2011,133,20060; HongX., WangD., YuR., etal., Chem.Commun., 2011,47,5160).Although these methods above can realize the synthesis of various metals or alloy nano-wire, but the nano wire draw ratio that this kind of solution phase synthesis obtains often all is less than 1000, microcosmic can be referred to as nano wire, but still belong to the sightless fine particle of naked eyes on a macroscopic scale.The metal nanometer line that this kind of synthetic method obtains not only size is little, and time consumption and energy consumption, is difficult to realize scale of mass production.Chinese patent application 201510019494.2 just utilizes metal nanometer line, itself and cotton compound is obtained and has certain flexible conductive fiber.But this patented method process route is complicated, particularly repetitious solution impregnation, dry and Polymer adsorption again subsequently and solidification, except the uniformity affecting product also affects efficiency.Particularly limit its application in multiple types textile fabric.Single-layer graphene and polypropylene fibre are then compounded to form conductive fiber by the people such as Aveiro university of Portugal HelenaAlves, but the electric conductivity being spun into cloth is poor, complex process, (NevesA.I.S. with high costs, BointonT.H., MeloL.V., ScientificReports2015,5,09866).Based on above problem, develop a kind of high environmental resistance and simple and easy to do, be convenient to large-scale production and application and the conductive fiber that can carry out traditional textile processing to prepare shape, size any adjustable while effectively keep fiber self the electrode manufacturing method of characteristic just seem very necessary.
