| Abstract | This work reports the preparation of a highly-conductive silver coating using silver micro flakes via a facile method of acid treatments. In this method, micron-sized silver flakes, suspended in isopropanol alcohol at 1 wt%, were deposited on polypropylene substrates, forming a silver coating with a surface coverage of ~7 × 10$^{−10}$ g/m$^{2}$. This coating was initially non-conductive. It was found that through a simple acid treatment by either immersing the coating in HCl solutions or exposing the coating to HCl vapors for a brief period <30 min, the conductivity of the coating could be improved dramatically, reaching a conductivity as high as ~3.8 × 10$^{4}$ S/cm. To investigate the mechanism, different solutions (acid, alkali and salts) were tested. The results indicated that both the Cl$^{−}$ and H$^{+}$ ions were responsible for the increased conductivity, likely by partially replacing or removing the lubricant layers coated on the silver flakes. Furthermore, we applied this method to fabricate flexible electrical circuits by embedding silver patterns in plastic sheets or polydimethylsiloxane elastomers. The resultant circuits were conductive and bendable without losing conductivity, showing a good potential application in soft electronics. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
