Beneficial effects of the present invention
Present invention is generally directed to flexible touch screen, using completely new graphene/nano silver wire/graphene combination electrode, To replace traditional ITO electrode, touch screen full flexible is realized.Due to conventional polymer film used by flexible touch screen Not as good as the hardness and water oxygen isolation capacity of glass, it is easy to the problems such as causing the aging and breakage of metal electrode, and graphene has There are very high hardness and isolation water oxygen ability, the service life of touch screen can be effectively improved.The surface of upper layer graphene film simultaneously Cladding can further increase the conductivity of nano silver wire, to improve the comprehensive performance of touch screen.It is prepared using the present invention Flexible touch screen is at low cost, and performance is good, and the service life is high, can arbitrarily be bent, can further push the development of Flexible Displays industry, full The needs of foot future flexibility industry development.
Description of the drawings
Patent content of the present invention is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural schematic diagram of flexible touch screen of the present invention.
Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to Specific implementation mode, the present invention is further explained.
As shown in Figure 1, the figure is the structure chart of flexible touch screen, wherein S01 is flexible base board, and S02 is the first graphene Layer, S03 are silver nanowire layer, and S04 is the second graphene layer, and S05 is OCA glued membranes, and S06 is the second graphene layer, and S07 receives for silver Rice noodles, S08 are the first graphene layer, and S09 is flexible base board.
A kind of flexible touch screen, including flexible base board have transparent conductive film and insulated rubber film, institute on the flexible base board The transparent conductive film stated is using graphene/nano silver wire/graphene multi-layer compound film in the specific preparation process of the present embodiment It is as follows：
PET film is placed on spin coater first, the graphene dispersion of upper 4mg/ml is then dripped on PET film surface Liquid starts spin coater, and control rotating speed is 1200rpm, and after spin coater stalling, film is placed 120 DEG C of processing on hot plate 10min.After equal film coolings to room temperature, film is placed on spin coater, the nano silver wire dispersion liquid of 6mg/ml is added dropwise again, The dispersion liquid solvent is the mixed liquor of ethyl alcohol and isopropanol, after waiting solution uniformly to spread out, starts spin coater, rotating speed control exists 1500rpm rotates 1min, and film is transferred in heating plate 140 DEG C of processing 15min later, later repeatedly nano silver wire film Spin coating preparation process, obtain 3 layers of nano silver wire film.Then prepared film is placed on clean bench, it will The graphene dispersing solution of 2mg/ml is added in spray gun, and adjust spray gun goes out liquid speed degree, utilizes spray coating method in nano silver wire later Film surface deposits a layer graphene layer, and film is placed 140 DEG C of annealing 10min on hot plate, final acquisition later High conductivity, the composite conductive thin film A of high transparency.It being found through measuring, the square resistance of film is 2-6 ohms/squares, and Light transmittance under 550nm visible wavelengths reaches 84%, in terms of fully capable of being used in touch screen.
Above-mentioned step is repeated later and prepares otherwise see-through conductive film B, is distinguished using dry etching or wet etching Film A and B is graphical, adhesive layer OCA glued membranes then are coated in the second layer graphene surface of A films, later by other one The film B of the side of the part with second layer graphene layer is covered in OCA film surfaces, is placed on after pressure on hot plate and dries completely It is dry, then take out measurement.
In above-described embodiment step, flexible substrate material can also be flexible glass, PMMA films, polyester film, nylon Film and other laminated films.Film can first pass through the processing of plasma or UV/O3 before depositing graphene layer so that thin Film surface carries the specific groups of some oxygen components, is conducive to the uniform coating of graphene dispersing solution.
In above-described embodiment step, the deposition of film surface first time graphene layer can also use spraying or czochralski method, Used graphene dispersing solution can be dispersed in the reduced graphene powder in the organic dispersions such as DMF, ethyl alcohol, after pass through Ultrasound is evenly dispersed, and deposition forms a film on flexible substrates through the above steps.The graphene being compared to prepared by CVD method is flexible Film, the graphene film cost prepared using solwution method is relatively low, simple for process, after 120 DEG C of heat treatment, graphite oxide Alkene film portion is reduced to graphene film, and equally distributed graphene film can play completely cuts off hard object and water oxygen well Effect, extends the service life of touch screen.
In above-described embodiment step, the coating of nano silver wire film can also be realized by spray coating method or czochralski method, silver Nano wire can be dispersed in a variety of solution such as water, ethyl alcohol, isopropanol, and the preparation of multilayer nano silver wire can improve nano silver wire Between overlap joint probability, reduce square resistance, improve the sensitivity of prepared touch screen.
In above-described embodiment step, the deposition of the graphene layer of film top layer is carried out using spray coating method, mainly due to After nano silver wire is heat-treated, surface has certain hydrophobicity, therefore the mode of spin coating or lifting is difficult in silver nanoparticle The upper uniform graphene layer of line film surface deposition, therefore the deposition of this layer is mainly realized by spraying.In addition used by Graphene dispersing solution can be dispersed in the reduced graphene powder in the organic dispersions such as DMF, ethyl alcohol, after through it is ultrasonic uniformly Dispersion.The thickness of top layer's graphene film is 2-10nm, is acted on primarily to further increasing every line of nano silver wire Between overlap joint the square resistance of film is reduced by the adhesive effect of graphene, improve the sensitivity of prepared touch screen.
In above-described embodiment step, used glued membrane is OCA glued membranes, other certain similar insulated rubber films are in the present invention It can also be used in patent, primarily serve isolation and bond the effect of two layers of conductive film.
Touch screen prepared by this method has splendid stability and resolution because of the combination of nano silver wire and graphene The problem of rate, and since by the way of spin coating, film is uniform, bad point and Low Response is not present in entire touch screen panel, sensitivity Height, and flexible test stability is preferable, disclosure satisfy that the needs of future development.
Above-described embodiment does not limit the invention in any way patent, every by the way of equivalent substitution or equivalent transformation The technical solution of acquisition is all fallen in the protection domain of patent of the present invention.
