Abstract

The invention provides a magnetic field and application of magnetic nanowires in a transparent conductive film. The magnetic nanowires are arranged linearly in the transparent conductive film through the magnetic field. The magnetic nanowires are simple in process and are rapidly oriented to be arranged in columns under the effect of the magnetic field only. The invention also finds that through the combination of a microcosmic orderly magnetic nanowire layer and a transparent conductive nanolayer frequently used in the field, and under the circumstance that the quantity of a conductive material is not changed, the conductivity is improved greatly and the transmittance keeps unchanged.

Description

technical field [0001] The present invention relates to a conductive thin film, and more particularly relates to the application of a magnetic nanowire in a transparent conductive thin film, the transparent conductive film and a preparation method thereof. Background technique [0002] There are many kinds of transparent conductive film materials, among which metal oxides dominate, such as indium tin oxide (Indium Tin Oxide, ITO), etc., which are widely used in the modern microelectronics industry. However, due to the brittle texture of ITO itself and the high cost of film production and preparation, its development is limited in many aspects, especially in the field of flexible electronics. In recent years, many new materials such as carbon nanotubes, graphene, metal nanowires and conductive polymers have emerged. Their excellent photoelectric properties are in line with the future development trend of thinner and more flexible devices, and have the potential to become a ...
