| Abstract | A novel polyamide 6/silica nanocomposite containing epoxy resins (EPA6N) was prepared via in situ polymerization using tetraethoxysilane (TEOS) as the precursor of silica. The dynamic rheological properties of pure PA6 and EPA6N at temperatures of 225 and 235 °C were investigated. The results of transmission electron microscopy (TEM) and atomic force microscopy (AFM) indicate that the silica particles are well dispersed in the polyamide 6 matrix on about 30 nm in diameter, which demonstrates that this method can effectively avoid agglomeration of the inorganic particles. The rheological results suggest that pure PA6 shows Newtonian behavior. However, the novel EPA6N exhibits a solid-like rheological behavior, which is due to the small size, large surface of silica particles and the stronger polyamide 6-silica chemical bond formed through the reactions of epoxy resins with end groups of PA6 molecular chains. The EPA6N also exhibits higher melt viscosity, storage modulus and loss modulus than those of pure PA6. |

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.
