Abstract:To produce patterns of porous polystyrene films that can be used as standards to be compared with cancer cell patterns, thin films were made by dissolving polystyrene (PS) and polybutylmethacrylate (PBMA) in tetrahydrofuran, then PBMA phase was removed using acetic acid (AA) to generate rough surfaces. The mixture of %PS/%PBMA was formed from the following weight ratios 1/99, 5/95,…, 90/10, 99/1. The highest water contact angle (WCA) for 40/60 porous polystyrene film was (139.4 ± 1 ), exceeding the WCA of the … Show more
