The present work demonstrates transparent polymeric flexible gas barrier films, via mimicking structures of nature. SiO2 hydrophilic regions have been formed by mesh mask deposition and the nano-patterned hydrophobic surfaces were fabricated by nano-imprinting techniques. The characteristics of the moisture repellent hydrophobic surfaces and the moisture transfer from hydrophobic to hydrophilic regions are shown to yield enhanced moisture barrier performances.
