Preparation method for transparent conductive metal network

The invention discloses a preparation method for a transparent conductive metal network. The preparation method comprises the following steps: a) preparing a nanofiber network through electrospinning; b) evaporating a metal layer on the nanofiber network so as to obtain a metal-polymer network complex; and c) removing a metal in the metal-polymer network complex so as to obtain the transparent conductive metal network. The invention has the following beneficial effects: downstream tedious etching and patterning processes are avoided in preparation of a conductive film prepared from the flexible transparent metal network, demands of touch screens and display panels for patterning can be directly met, and online production can be realized.
