| Abstract | Due to the need for reducing system size and weight while increasing performance, many military and commercial systems today require high-temperature electronics to run actuators, high-speed motors or generators. Of the many passive devices required to satisfy the needs for a complete high temperature system, none has been more problematic than the capacitor, particularly for larger devices requiring values of several micro- or milli-farads. Here we introduce a polymer metal composite we have recently developed that meets typical aerospace design constraints of high reliability, robustness, light-weight, as well as high temperature (up to 300°C) operation. Our recent discovery of the capacitive behaviour in perfluorinated sulfonic acid polymers sandwiched between metal electrodes has lead to the exciting development of high temperature capable high density passive storage components. These composites exhibit capacitance per unit planar area of ∼1.0 mF $cm^{−2}$ or 40 mF/g for a ∼100 µm-thick polymer substrate, with only a small predictable decrease in capacitance immediately after heating to 100°C followed by constant capacitance up to 300°C. Here we report the design and testing of single step microfabrication of metal electrodes to these polymer composites sandwiched between two thin metal films along with their performance at high temperatures. |

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.
