Abstract | The temperature dependence of the resistivity and dielectric properties of carbon black-polyethylene composites was measured in the temperature range from room temperature to 95 /spl deg/C. The composites show a dielectric relaxation, which obeys a Cole-Cole circular arc law. The strength of relaxation, /spl delta/ /spl epsi/, and the parameter /spl beta/, a measure of the distribution of relaxation time, were estimated from the Cole-Cole plot. It is suggested that the rapid increase of resistivity observed about 70 /spl deg/C is due to a scission of conducting paths caused by the thermal expansion of the resin, because of the increase of /spl delta/ /spl epsi/ above 70 /spl deg/C. The decrement of /spl beta/ indicates that the scission makes the distribution of relaxation broader. In the temperature region below 70 /spl deg/C, /spl delta/, /spl epsi/ decreases with heating. It is concluded that branches likely combine to conducting paths, bringing about a mild increase in resistivity with increasing temperature.< |

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.
