Description
Technical field
The present invention relates to field of electronic materials, particularly a kind of method of preparing conductive metal film, the especially preparation method of metal transparent conductive film.
Background technology
Transparent conductive film has satisfactory electrical conductivity, and has high transmission rate in visible-range, is widely used in the fields such as flat panel display, thin-film solar cells, transducer, touch-screen and extending electronics.Based on conductivity, consider, metal transparent conductive film, especially nano silver wire transparent conductive film are to be expected to one of candidate scheme replacing commercialization tin indium oxide ITO most.But because of the stabilizer of the peripheral parcel conventionally of nano silver wire one deck decomposition temperature up to 350-400 degree, as polyvinylpyrrolidone (PVP), line Contact resistance is larger, conventionally needs 200 degree high-temperature process, and some low costs, base material that glass transition temperature is low cannot be used.In addition, the adhesiveness of nano silver wire and substrate is effectively improved always, and its commercial applications is restricted.
The related work of report is main mainly with promoting conductivity separately at present, and the work that adhesiveness is improved is less, improves conductivity and adhering work still less simultaneously.The method that solves the adhesion issues of nano silver wire conductive film and substrate is generally in the dispersion liquid of nano silver wire, to add the agent of polymer gluing, polymer gluing agent film forming together with nano silver wire, after solvent seasoning, the agent of polymer gluing is tightly sticked together nano silver wire conductive film and substrate.The method has strengthened the adhesiveness between nano silver wire conductive film and substrate, but, because the polymer gluing agent adding is attached to the periphery of nano silver wire, the contact resistance between silver-colored line in nano silver wire is sharply increased, seriously reduced the conductivity of nano silver wire conductive film; Secondly because nano silver wire General Decentralized is in lower boiling ethanol or isopropyl alcohol, the polymer gluing agent therefore adding must can be dispersed or dissolved in these solvents.Yet its opposing solvent of material and the wet environment ability that can be dissolved in polar solvent are often poor.Therefore, the long-term reliability that adds membership reduction product of polymer gluing agent.
For reducing silver-colored line Contact resistance, part Study person carrys out Processing Ag nano wire film with high energy pulse irradiation etc.Use high energy source is processed, although film conductivity increases, efficiency is also higher, only needs several microseconds, easily occurs oversintering, and conductivity peak point is also that conductivity starts the point declining conventionally, so more difficult control during practical operation.
Also there is no so far a kind of effective, low-cost, high efficiency, can improve the method for nano silver wire conductive film adhesiveness and conductivity simultaneously.
Summary of the invention
