Definitions

the present invention discloses a flexible transparent conductive electrode.
the flexible transparent conductive electrode is made of transparent flexible base materials and a transparent flexible substrate coated with a silver nanowire coating.
the process of fabricating the flexible transparent conductive electrode comprises a few steps as followings: adding silver nanowire aqueous dispersion, aqueous acrylic resin, triethylenetetramine, 1-2 parts of p-methylsulfonyl toluene, 0.1-0.3 pars of hydrogenated castor oil and a mixture solvent into a vacuum mixer where evenly mixed, vacuum defoamed, and thus the coating is prepared.
the concentration of the silver nanowire in the coating is 2-10mg/mL and the mixture solvents used are the mixture of alcohol and ketone.
the film is coated with above coating and moved into a vacuum dryer to be dried at 150°C for 3-10min so that the solvents in the coating are completely volatilized and the flexible transparent conductive electrode is obtained.
the flexible transparent conductive electrode of the invention has characteristics of the lower conductive resistivity, less stacks of silver nanowires, higher uniformity of conductivity and better optical transmittance comparison with the existing products.
the present invention relates to a technology of silver nanowires, particularly relates to a flexible transparent conductive electrode. insert content of description insertion page 1a here
US 2015/166798 A1 discloses a transparent conductive film including metal nanowires and a colored compound adsorbed by the metal nanowires.
the metal nanowires are a material which absorbs light in the visible light region, and also each has a functional group which is bound to a metal constituting the metal nanowire.
Metal oxides especially ITO, has the characteristics of good optical transmittance in visible region and low resistivity which have been hot spots in researches and applications of transparent conductive electrodes in the past 5 decades.
metal oxides have the disadvantages as limited conductivity, brittle and hard to deform.
Concurrently, scarce resources and risen prices are unable to meet the requirements for developing the modern optoelectronic devices.
Two dimensional micro-nano new materials and structured thin film electrodes are new fields of transparent conductive electrodes with the development of micro nanotechnology in recent years, such as conductive thin film of polymers, carbon nanotube film, graphene film and metal nanowire film.
Transparent conductive film has advantages of not only great conductivity but also good optical transmission while nanometallic silver wire electrode's are excellent.
Micro-nano silver wires can be used as electrode materials with less energy consumption (compared with electrode of oxide thin film) since silver is an electric conductor with great electrical conductivity.
micro nano structure of metal with plasma effect increases transmittance while diameters of micro silver nanowires' particles are smaller than the incident wavelength of visible light, and perfect photoelectric properties are achieved for electrodes.
micro silver nanowire electrode is benefit for flexible industries and large scale productions with lower cost. Therefore, the micro silver nanowire electrode will be a favorable alternative to ITO transparent conductive electrode.
the additives for preparing coating fluid of micro silver nanowires determines performances of the electrode. Therefore, various additives are used to prepare different coating fluid for different properties in order to get better performances. Properties as conductivity and flexural endurance are still to be improved by using current formula.
