Microstructures in the dual- and three-level hierarchical templates are replicated on the surfaces of large-sized polypropylene (PP) samples using microinjection-compression molding (-ICM) in a single step.Results indicate that the single- and dual-level structured surfaces can be molded via the former template under lower and higher compression forces

respectively.The single-level micro blade structure yields an increase in static contact angle (CA) from the intrinsic value of the PP (85.0) to 134.2 on the molded surface.The dual-level structure involving micro blades and micro pyramids results in the lotus-leaf effect (CA150

rolling angle RA5) on the surface.The 250 m diameter micro columns

the top surfaces of which show the aforementioned dual-level microstructure

are uniformly distributed on the three-level hierarchical surface molded via the later template.The CA and RA values on this surface are 164.5 and above 90

respectively.Thus a functional surface displaying the petal effect is obtained.The high level of RA is resulted from the localized noncomposite wetting state near the upper edge of micro columns.This work gives an insight into the design

manipulation and mass production of superhydrophobic surface.
