Substrate including nano/micro structure, method for manufacturing the same, method for refining nano/micro structure, method for manufacturing nano/micro structure network, and manufacturing apparatus therefor

A method for manufacturing a substrate including nano/micro structures, comprising:

• forming a nano material on an upper surface of an auxiliary substrate;
• forming nano/micro structures on the upper surface of the auxiliary substrate;
• coating a base solution on the nano/micro structures to fill gaps between the nano/micro structures and the auxiliary substrate and between the nano/micro structures;
• forming a base substrate covering the nano/micro structures by performing a heat treatment to the base solution;
• removing the auxiliary substrate from the base substrate to expose a main planar surface at a top surface of the base substrate adjacent to the upper surface of the auxiliary substrate, the exposed main planar surface including at least a first portion without the nano/micro structures and the nano material, a second portion including the nano/micro structures, and a third portion including the nano material, wherein the first portion, the second portion, and the third portion are disposed in a same plane;
• and
• performing a heat treatment process to the base substrate for improving the bondability of the nano/micro structures after the main planar surface is exposed, and
• wherein the nano material includes at least any one of graphene flake, single-walled CNT, double-walled CNT, multi-walled CNT, C60, C85, or C70, and
• wherein the nano/micro structures include metal nano wires, and
• the nano material improves the bonding and a dispersity of the nano/microstructures compared to the base substrate without the nano material.
