“…For patterning on a curved surface, we used patterned polyvinyl alcohol (PVA) foils as stamps (Schaper 2003) as the material is transparent to UV light, thereby exposing the filmstamp interface to UV light for making the patterns per- manent. In case of patterning of curved surfaces too, the pattern transfer takes place directly in the solid phase, in contrast to existing reported methods where the liquid is heated beyond its glass transition temperature and the patterning takes place in liquid state.…”

This is a brief review of our recent and ongoing work on simple, rapid, room temperature, pressure-less and large area (~ cm 2 ) imprinting techniques for high fidelity meso-patterning of different types of polymer films. Examples include soft solid polymer films and surfaces like cross-linked polydimethylsiloxane (PDMS) and polyacrylamide (PAA) based hydrogels, thermoplastics like polystyrene (PS), polymethylmethacrylate (PMMA) etc both on planar and curved surfaces. These techniques address two key issues in imprinting: (i) attainment of large area conformal contact with the stamp, especially on curved surfaces, and (ii) ease of stamp detachment without damage to the imprinted structures. The key element of the method is the use of thin and flexible patterned foils that readily and rapidly come into complete conformal contact with soft polymer surfaces because of adhesive interfacial interactions. The conformal contact is established at all length scales by bending of the foil at scales larger than the feature size, in conjunction with the spontaneous deformations of the film surface on the scale of the features. Complex two-dimensional patterns could also be formed even by using a simple one-dimensional master by multiple imprinting. The technique can be particularly useful for the bulk nano applications requiring routine fabrication of templates, for example, in the study of confined chemistry phenomena, nanofluidics, bio-MEMS, micro-imprinting, optical coatings and controlled dewetting.

Fine-structured ZnO patterns with sub-micrometer based on a replication method was fabricated. A replication method was used mixtures of polyvinyl alcohol (PVA) and ZnO nanosized particles in water. The mixtures were then filled in a quartz mold with different pattern sizes and dried at room temperature. After the drying, the PVA and ZnO dried film was detached from the mold. Through burn-out at various sintering temperatures, ZnO patterns with line and space patterns as smalls as submicrometer in size were successfully fabricated. The results demonstrated possibilities to produce inorganic materials with various compositions and structures with a facile approach and a simple method.
