Buckling Nature of the Pre-Strained PDMS (IMAGE) World Scientific Caption The buckling nature of pre-strained PDMS was applied to the investigation of the dependency of surface hydrophobicity on different geometries of wavy polystyrene thin films, which were fabricated using colloidal self-assembly. This approach can be further applied for fabricating various polymeric nano-films with controlled hydrophobicity.
