A facile method for forming both hydrophilic and hydrophobic surfaces is proposed here. Synthetic opal composed of mono-sized spheres of 250-290 nm was placed in contact with plastic substrates at 190 degrees C and then peeled off from the substrates at room temperature. The peeling process allowed a formation of hemisphere hole arrays of 200-230nm on the substrate, which caused increased hydrophobicity. Because of partially remaining opal on the substrate, a hydrophilic and colorful surface was also obtained.
