Preparation of lotus-leaf-like polystyrene micro- and nanostructure films and its blood compatibility

The lotus-leaf-like polystyrene (PS) micro- and nanostructure film was prepared and characterised. This film reveals superhydrophobicity and good blood compatibility. The realization of this hierarchical PS nanostructure film could be important for further understanding non-wettability of biological surfaces with micro- and nanostructure and application in biomedical devices.
