| Abstract | Vapor-grown carbon fibers have been obtained by pyrolysis of hydrocarbons, such as benzene and methane, by a catalytic effect of ultrafine metal particles(i). Two different methods, have been developed for successful formation of the fibers, the substrate method and the aerogel system(1)(2)(3).By the substrate method, thick(/spl tilde/10/spl mu/m diameter) and long fibers(/spl tilde/20cm long) can be grown. By the aerogel system, where the catalytic particles are floating in the reaction chamber, very thin fibers of less than 1/spl mu/m in diameter and less than several mm in length have been effectively produced. From gas phase, these carbon fibers have a high degree of preferred orientation and exhibit a high degree of graphitizability high enough for intercalation. The intercalated vapor-grown carbon fibers show high electrical conductivity and mechanical performance. By choosing suitable intercalants, air and thermally stable compounds can be obtained. These compounds are applicable for practical application as a light weight conductor in plastic composites. In the present paper, the preparation and electrical properties of bromine intercalated vapor-grown carbon fibers having air and thermal stability are shown, and the electronic structure giving rise to the high conductivity is 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.

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.
