| Abstract | The existence of space charge has a great effect on breakdown characteristic and is the main reason leading to dielectric breakdown. Fluorination as change the chemical component in surface layer of polymers should give rise to the corresponding change in electrical properties of the surface layer thus influence the charge injection from electrodes. This paper presents a study aimed at clarifying the effect of fluorination on space charge behavior in multilayered polyimide films. The surface chemical compositions of the fluorinated films together with the original (unfluorinated) film as a reference were characterized. The space charge distributions in multilayered polyimide Films were measured using the pulsed electro-acoustic (PEA) method. Obtained results show that the space charge distribution of multilayered film stacking with five fluorinated samples is quite different from that of multilayered film stacking with five untreated samples. It is also suggested that the fluorination can significantly suppression the injection of space charge. |

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.
