| Abstract | Most polymer dielectric materials can store surface charges, which may accumulate and cause an electrostatic discharge (ESD). This phenomenum has become a serious problem because the electromagnetic noise associated with an ESD damages electronic circuits in various kinds of apparatus. The accumulation of surface charge on a polymer dielectric material is conventionally prevented by using surface-active agents or conductive fillers to reduce the surface resistivity, thus enabling the charge on the polymer to leak away. New anti-ESD polymers, on the other hand, contains polymer solid electrolytes and prevent ESD even though their resistivity is high. Since these polymers have charges in them originally, the measurement of their space charge distribution should be helpful in describing their features. We therefore measured the space charge distribution inside some polymer films by using the newly developed pulsed electroacoustic method and showed that a poly(vinyl chloride) film initially has internal charge and generates an electric field by itself. We found that three kinds of anti-ESD materials using different polymer solid-electrolytes can produce the internal space charge electric fields under DC voltage application, thereby compensating the external electric field. These results suggest that space charge measurement is useful in fundamental research of ESD. |

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.
