We report an extremely simple method of making an optically transparent superhydrophobic polydimethyl-siloxane (PDMS) thin film using underexposed and underbaked positive photoresist (PR) mold. Significant under soft-bake condition makes PR retain good amount of solvents, which greatly increases the dissolution rate of the PR during developing. A combination of optimal underbaking and underexposure condition created a unique hierarchical micro-/nano- structure on the PR mold, and inverse image of the PR mold was replicated to create a hierarchical micro/nano structured broccoli-shaped PDMS thin film. A 100-nm-thick fluorocarbon film was optionally deposited on the broccoli-shaped PDMS film to further enhance superhydrophobicity. Advancing and receding angles of the film for 4- μL water droplet were found to be 161.33±0.763° and 133.33±0.29°, respectively, showing superhydrophobicity. It was also found that the optical transmittance at around 550 nm for this PDMS film was approximately 90%. |
