Abstract
A transparent conducting film comprises a transparent base body which is further coated with a transparent conducting coating, and conducting fibers are distributed in the conducting coating. The method for forming the conducting coating comprises the steps that first, the conducting fibers are prepared, then the conducting fibers are scattered in bonding resin, afterwards, the binding resin which is provided with the conducting fibers in a scattered mode coats the transparent base body, and the conducting coating can be formed after the bonding resin is cured. The method for preparing the conducting fibers comprises the steps that conducting materials are placed in bonding resin melt to be mixed together, and then the conducting fibers are manufactured through high-speed centrifugal spinning with the speed being more than 20000 turns/minute. According to the transparent conducting film, a conductive path is formed in the conducting coating by the conducting materials, the conductivity and the light transmittance can be adjusted by adjusting the content of the conducting materials, the conducting materials coat the inside of the conducting coating, the phenomena of disengaging, oxidation and the like can be effectively avoided, preparing is easy, operation can be conducted only by centrifugal spinning equipment, and the cost is low.
Description
Technical field
The present invention relates to a kind of nesa coating.
Background technology
Nesa coating is widely used in touch control liquid crystal panel, organic diode of giving out light (OLED) and electromagnetic shielding, the fields such as smart mobile phone touch screen, Electronic Paper, solar cell.At present, more common nesa coating has ito film and metal film two kinds, the former is on transparent glass or plastic base surface, the transparent conductive material of one deck Indium-tin oxide film (ITO) etc. is formed by the method for evaporation or sputtering, the latter is on transparent glass or plastic base surface, by the method for metal-plated or evaporation, forms metallic film on whole surface, then by photoetching, it is processed, metal level is etched into fine metal grill.
Though extensive use, also there are some defects in ito film: then its transmitance is difficult to improve, is difficult to keeping there is risk of rupture when reducing square resistance, overbending while transmitance, poor plasticity is difficult to meet the needs of large flexible occasion not fill reflectance coating, in addition, phosphide element is very rare, is not suitable with sustainable development.Although metal film conductivity is better, when processing metal film, need to remove most metallic film, there is the shortcoming that waste is many, production cost is high.
In recent years, scientist proposes some new methods.Directly in the method for transparent substrates surface one-shot forming grid-shaped metal wire.Wherein one is by raw material fusion such as Nano silver grain, organic solvent, surfactant and aqueous solvents and emulsification, form Ag silk ink, when this ink is coated on transparency carrier surface, because the difference of the polarity of solvent, surface energy and volatility, be able to the silver-colored reticulated structure automatically forming arbitrary shape at substrate surface, after oversintering, just become nesa coating.Some utilize the nesa coating of radio frequency to be also in succession developed, the touch panel that Fraunhofer IPA utilizes carbon nano-tube to make.On the film of PET resin, be specifically coated with the mixed liquor of electroconductive resin PEDOT-PSS and CNT, then form conducting film; Taiwan CMO also uses CNT to obtain nesa coating as the current-carrying part of touch-screen; Due to the discovery of all good materials of this light transmission of Graphene compliant conductive performance, many researchers turn one's attention to Graphene, the touch panel of 4 layer graphenes formations of the obtained 30in size such as Samsung, electrical sheet resistance is 30 Ω, light transmittance reaches 90%, but the bottleneck realizing batch production due to Graphene is not yet broken through, and can only accomplish very small size at present, the larger industrial applications limiting current Graphene.Existing above-mentioned conducting film all needs more difficult in the preparation.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing conducting film, the invention provides one and preparing comparatively easy, lower-cost nesa coating.
The technical scheme that the present invention solves its technical problem is: a kind of nesa coating, comprises transparent base, described transparent base is also attached with the conductive coating of layer of transparent, is distributed with conductive fiber in described conductive coating;
The formation method of described conductive coating is: first prepare conductive fiber, then by wire fiber dispersion in bonding resin in, afterwards by resin-coated on described transparent base for the bonding being dispersed with wire fiber, until bonding resin solidification after;
Wherein the preparation method of conductive fiber is: conductive materials is placed in bonding resin melt blended, then obtains through the high speed centrifugation spinning of more than 20000 revs/min.
Further, described conductive materials is conductive black, or is conducting metal nano particle, or carbon nano-tube, or nano-silver thread.
Further, described bonding resin is PETG or polyethylene or polypropylene or Merlon or polystyrene or phenolic resins or urea-formaldehyde resin or polyurethane resin or vinylite or polyacrylate resin or polyvinyl alcohol resin or Petropols or polyamide or furane resins or PEDOT:PSS.
Beneficial effect of the present invention is: conductive materials forms conductive path in conductive coating inside, conductivity and light transmittance can be regulated by regulating conductive materials content, conductive materials is coated on conductive coating inside, can effectively prevent from coming off, the generation of the problem such as oxidation, and wait fairly simple in the preparation, just can operate to needs centrifugal spinning equipment, cost is comparatively cheap.
