Elastic conductor is a kind of when stretching and bend, a kind of novel conductor that resistance remains unchanged substantially.Be widely used in scalable electronic device field such as artificial skin, flexible display and transducer, intelligent robot etc.Traditional plain conductor and silicone based circuit board are due to the defect of its rigidity, and the use in flexible electronic device is very restricted.Current various countries scientist to develop high-elongation, high resilience, low hot strength, high conductivity elastic conductor tool have a wide range of interests.Developing high-performance elastic conductor is one of difficulty realizing capturing required for flexible electronic devices industrialization of new generation.
Traditional elastic conductor is that electric conducting material (as carbon black, metal dust, carbon nano-tube) is directly mixed to get elastic conductor with elastomeric polymer, the addition of electric conducting material all has a great impact the conductivity of elastic conductor and elongation, under few additive, although good percentage elongation, conductivity is too low; And addition is when increasing, elongation has and greatly reduces.In addition, the conductivity of such elastic conductor is all very little (is less than 0.01Scm
-1), application is very limited.Along with the development of nanometer technology, nano material quote the performance greatly promoting elastic conductor.Conventional method has: micron-sized wire a) preparing undaform in elastic substrates; B) load last layer conductive film, conductive nano-particles, conducting nanowires etc. in the elastic substrates stretched in advance, then unclamp the conductive surface that elastic substrates just can produce undaform; C) elastomeric polymer is filled directly in the electric conducting material with three dimensional micron or Specific surface area material.And this several method is all difficult to extensive preparation, cost of manufacture is high, still has very large gap with practical application.
Nano silver wire with its excellent optical property, electric conductivity and stability flexible transparent electrode field obtain apply widely.But the application in elastic conductor field or seldom, mainly by the fragility of nano silver wire and limited length limit.But up-to-date research finds that nano silver wire is under the protection of polymer, greatly improve the fragility of silver-colored line, and the preparation of nano silver wire also obtain important breakthrough, the length of nano silver wire can reach 500 microns.As Germany " advanced material " (Advanced Materials, 24 phase in 2012 5117 pages) report and nano silver wire film is embedded into polydimethylsiloxane rubber obtains the good elastic conductor of tensile property, under 0 ~ 50% elongation, resistance keeps constant substantially, but first time is when stretching, resistance variations still clearly, and nano silver wire at 10 ~ 60 microns, this long nano silver wire is difficult to extensive synthesis.And then, another section based on nano silver wire elastic conductor Germany " advanced material " (Advanced Materials, 24 phase in 2012 3027 pages) upper report, this is operated in synthesis ultra-long silver nanowire and obtains important breakthrough, and the length of nano silver wire reaches 500 microns.Be prepared into film by this ultra-long silver nanowire to load to again in elastic substrates, obtain elongation when reaching 450%, still can keep good conductivity.But the synthesis of this ultra-long silver nanowire is very loaded down with trivial details, be difficult to extensive synthesis.
Up to the present, preparing elastic conductor with nano silver wire is all based on two-dimentional nano silver wire network, and the quality of the conductivity of elastic conductor is just the number of contact in two-dimentional nano silver wire network, and contact is more, and conductivity is better.But this two-dimensional network is very limited to the ability to bear stretched, although use the nano silver wire of 500 microns can improve the tensile property of elastic conductor, the elongation of elastic conductor is also difficult to more than 80%.
