| Abstract | Template-based methods are a commonly used way to prepare superhydrophobic surfaces, in which, one of the critical issues, is template fabrication. In this work, a template with a dual-scale hierarchical structures fabrication method is investigated, in which, using the Cr and photoresist as etching mask, the fused silica glass substrate is etched in a buffered hydrofluoric solution. Optical photos and atomic force microscopy (AFM) scans show that the excellent ordered and uniform microstructures with a feature size less than 4 μm combining with the nanostructures with a feature size of about 20–30 nm on the etched surface have been fabricated, indicating hierarchical structures being obtained. Then the template with dual-scale structures is used as a master template and experiments of pattern transferring to PDMS and photoresist by cast moulding and by imprint lithography, respectively, have been conducted. The duplicating fidelity is characterised through optical photos and AFM scans. The contact angles of water on various fabricated surfaces are characterised and the influence of the surface roughness on wettability has been discussed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
