POLYMER THIN FILM OF POROUS STRUCTURE WITH SELECTIVE ETCHING AND METHOD THEROF, CHEMICAL SENSOR USING THE SAME

摘要

The present invention relates to a method for manufacturing a polymer thin film having a porous structure through selective etching with improved sensor performance through a polymer thin film having an increased surface area having a rough surface and a porous structure, and a chemical sensor using the same, and dissolved in P3HT and PCBM solvents. Preparing a mixed solution, coating the mixed solution on a substrate, heat-treating the coated substrate, and selectively etching the PCBM of the heat-treated substrate.
