NOVELTY - The method comprises mixing silver-miniature wires, non-conductive spheres, optional matrix material and optional carrier to form a mixture, applying the mixture to a surface of a substrate to form a film, and removing volatile components from the film formed on the substrate. The non-conductive spheres have an average particle size of less than or equal to 300 mu m. The method comprises providing a silver ink-core component containing greater than or equal to 60 wt.% of silver nanoparticles dispersed in a silver carrier, and providing a cover component comprising a film-forming polymer, which is dispersed in a shell component.    USE - The method is useful for preparing a silver miniature wire film (claimed) that is useful in touch screens and photovoltaic cells.    ADVANTAGE - The method is capable of preparing the silver miniature wire film with reduced surface resistance and high transparency.    DETAILED DESCRIPTION - The method comprises mixing silver-miniature wires, non-conductive spheres, optional matrix material and optional carrier to form a mixture, applying the mixture to a surface of a substrate to form a film, and removing volatile components from the film formed on the substrate. The non-conductive spheres have an average particle size of less than or equal to 300 mu m. The method comprises providing a silver ink-core component containing greater than or equal to 60 wt.% of silver nanoparticles dispersed in a silver carrier, providing a cover component comprising a film-forming polymer, which is dispersed in a shell component, providing a target, electrospinning of silver ink core component and the sheath component, treating the silver nanoparticles to form the silver miniature wires, recovering the silver miniature wires from the surface of the target, and selecting a silver support and a housing support. The core is deposited on the target, where a core-shell fiber has a core, and a shell surrounds the core. The silver nanoparticles are present in the core. The silver miniature wires have an average length of greater than or equal to 10 mu m. An interfacial tension between the sheath component and the core component of the silver ink is 2-10 mN/m. The silver nanoparticles are treated by internally photography. The electrospinning step comprises applying the silver ink-core component and the sheath component by a concentric annular nozzle with a central opening and a surrounding annular-opening. The silver ink-core component is supplied through the central opening at a flow rate of 0.1-3 mu l/minute, and the sheath component is supplied by the surrounding annular opening at a flow rate of 1-30 mu l/minute. The silver nanoparticles have an aspect ratio of less than or equal to 2. The carrier is water, and the silver support is a water-alcohol mixture in which alcohol is present in an amount of greater than or equal to 50 wt.%. The nozzle is adjusted based on a difference of the positive electrical potential to target electric potential of 3-50 kV applied to the substrate.
