In this research, a stretchable and non-sticky hydrophobic surface is developed using flexible polyurethane-based elastomer Vytaflex 20A. The hierarchical roughness of rose petals was replicated by soft molding method to achieve hydrophobicity. The morphological properties, wettability properties and mechanical properties of replicated micro/nanostructures were characterized. The replicated surface exhibited a similar micro/nanostructure to that of rose petal. Rose petal and replicated surface were highly hydrophobic and their static water contact angles (theta approximate to 124 degrees) are nearly equal. Contact angle hysteresis of the produced surface was measured (10 degrees) to be lower significantly than that of the fresh rose petal (50 degrees). The proposed surface is also highly stretchable having an elongation value of approximately % 700. Such surfaces can be a great candidate for providing easy to clean ability to deformable elastomer products.
