| Abstract | The knowledge of the structure-property relationship at nanoscale level is important to develop advanced dielectric polymer composites. Herein dielectric epoxy/polyhedral oligomeirc silsesquioxanes (POSS) composites with homogeneous nanostructure were prepared. Unlike the conventional inorganic nanoparticles (e.g., silica) used for polymer nanocomposite preparation, the POSS molecules used in this work have three advantages: a comparable size with the segments of polymer chains, being capable of reacting with the base polymer, good solubility in many solvents. These three advantages make the POSS be dispersed in polymers at a molecular level and thus their nano-effect could be fully utilized. Microstructure analysis by transmission electron microscopy, atomic force microscopy and X-ray diffraction confirmed the molecular-level dispersion of POSS in the epoxy composites. On this base, the partial discharge erosion resistance, frequency/temperature dependence of dielectric response, space charge distribution and breakdown strength of the epoxy/POSS composites were investigated. Moreover, the correlation between the nanostructure and properties of epoxy/POSS composites was documented. |

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.
