NOVELTY - Preparing flexible transparent conductive film based on micro-stereolithography technology involves placing clean substrate on printing platform of micro-stereolithography 3D printing system and fixing, and then using soluble photosensitive resin as 3D printing material to print groove structure on clean substrate of soluble photosensitive resin mold; using medical spatula to scrape conductive paste into groove structure of soluble photosensitive resin mold, filling groove, and then placing on 60-80 degrees C drying table for heating 5-15 minutes, solidify conductive paste to form conductive network embedded in soluble photosensitive resin mold; placing soluble photosensitive resin mold with conductive network in 1-3 wt.% sodium hydroxide (NaOH) solution and soaking for 1.5-2.5 hours to dissolve soluble photosensitive resin mold to obtain conductive network which is exposed on surface of clean substrate, rinsing residual NaOH solution gently with deionized water. USE - Method for preparing flexible transparent conductive film based on micro-stereo lithography technology. ADVANTAGE - The method enables to solve limitation of using conductive slurry and improves conductive film performance by structure design; is cost-effective, simple technique, wide applicability, large scale, and large area manufacturing.
