    • The present invention relates to a polymer-based large-area carbon nanomesh and a manufacturing method thereof and, more specifically, to a manufacturing method for a carbon nanomesh, comprising: a polymer nanofilm manufacturing step of manufacturing a polymer nanofilm by coating a substrate with block copolymers or mixed polymer solutions including at least two kinds of polymer solutions; a stabilization step of separating the polymer nanofilm by heat-treating the manufactured polymer nanofilm and allowing nanomesh forming polymers to form porous polymer nanomeshes by induced thermal stabilization while pore forming polymers are removed; and a carbonization step of manufacturing a carbon nanomesh by carbonizing the stabilized porous polymer nanomesh through a high temperature thermal treatment. Accordingly, the present invention provides the polymer-based large-area carbon nanomesh which is suitable for mass production since a process exhibits high reproducibility even through the process is simple by using cyclization reaction and phase separation properties of polymers and has excellent activity of a large area, and to the manufacturing method thereof.
