Abstract
The invention discloses a transparent electro-conductive nano silver wire printing ink that can be painted to form a single layer. The printing ink is composed of the following components in parts by weight: 10 parts of poly(3,4-ethylenedioxy thiophene)-poly(styrene sulfonic acid), 1 to 2 parts of stabilizing agent, 100 parts of surfactant, 0 to 15 parts of mixed solvent, and 50 to 200 parts of deionized water, wherein in poly(3,4-ethylenedioxy thiophene)-poly(styrene sulfonic acid), the weight ratio of poly(3,4-ethylenedioxy thiophene) to poly(styrene sulfonic acid) is 1:(2-8). The printing ink is evenly painted on a soft transparent substrate, then the printing ink is dried, the wet membrane thickness of the printing ink layer is 8 to 15 millimeters, and then the soft transparent substrate covered by the printing ink is sintered for 5 minutes at a temperature of 160 DEG C so as to obtain the soft transparent electro-conductive membrane, which has the advantages of low sheet resistance and high transparency.

Technical field
The present invention relates to nano wire field, particularly a kind of can the transparent conductive nano silver line ink of single layer coating and the preparation method of nesa coating.
Background technology
Transparent conductive film is a kind of a kind of film that can conduct electricity and have high transparency rate in visible-range, mainly contains metallic membrane system, oxide film system, other compound film systems, polymeric membrane system, compound film system etc.Metallic membrane system conducts electricity very well, but transparent rate variance.Semiconductor film series is just contrary, and poorly conductive, transparent rate is high.
ITO is current most widely used transparent electrode material, is applied to flat pannel display, touch screen, PDP display and correlation technique in.But this material is more crisp, preparation temperature is very high, and expensive, mainly because it needs at the rare indium of surface growth.Scientist is difficult to find the material with excellent comprehensive performance when finding the equivalent material of ITO.Scientific research finds that the nano-silver thread film of nanometer grade thickness shows the photoelectric properties equal with ITO, and still can keep good performance after flexure thousand times.
Current nano-silver thread electrically conducting transparent ink technology of preparing or employing first one primary coat bottoming, get at compacting nano-silver thread layer, and then adopt top to be coated with protection, or adopt direct pressing layer nano-silver thread layer, the technique adopting top to be coated with compacting protection above, make technique more complicated, considerably increase production cost simultaneously, and after being coated with top stopping off, when can overlap follow-up printing drainage strip and nano-silver thread layer, add the resistance of junction, defective products is increased greatly; Also someone adopts other macromolecule resins as the configuration of binder collocation nano-silver thread, but because of general macromolecule resin be nonconducting, thus make final conductive coating sheet resistance excessive, cannot processing requirement be met.
Summary of the invention
In sum, the present invention be necessary to provide a kind of can the transparent conductive nano silver line ink of single layer coating, only need one deck coating simply, then cover one deck silver sodium rice dispersion liquid, the nesa coating that sheet resistance is low, the transparency is good, do not affect subsequent conductive line design can be prepared into.
