According to recent research from Kanpur, India, "We report a simple yet robust and reproducible technique to create Surface patterns with submicrometer scale resolution On polymer film's coated on nonplanar and curved surfaces at room temperature, without applying any external pressure. The imprinting is achieved by using a flexible, patterned polyvinyl alcohol (PVA) stamp in a controlled solvent vapor atmosphere, where the patterned foil comes in adhesive contact with a swollen and softened polymer film."
"The stamp bends along the contours of the Curved surface to make a complete contact with a soft and swollen viscoelastic polymer film to make an imprint. The ...
