| Abstract | Mg-Al layered double hydroxide (LDH) was modified with sodium dodecyl sulfate (SDS) by regeneration method. Polyethylene/modified LDH composites (PE/SDS-LDH) were prepared by melt blending and solution mixing method. Maleated polyethylene (PEgMA) was used to improve the compatibility between LDH and PE. The dispersion of LDHs in PE matrix was investigated by X-ray diffraction (XRD) and scanning electron microscope (SEM). Thermal degradation of PE/SDS-LDH composites was characterized by thermogravimetric analysis (TGA). The results reveal that PE/PEgMA/SDS-LDHs microcomposites were obtained by melt blending method and PE/PEgMA/SDS-LDHs nanocomposites were prepared by melt blending PE with SDS-LDH/PEgMA master-batch obtained by solution mixing. Due to the thermal decomposition of LDHs at much lower temperature than PE, the degradation of composites begins at low temperature regardless of the dispersion of LDH in PE. The initial degradation temperature corresponding to 5% weight loss of nanocomposites is higher than that of microcomposites. Compared with microcomposites, the nanocomposites present the higher temperature corresponding to the maximum thermal degradation rate and more residues at the end of thermal degradation, indicating the better barrier properties and charring effects of nano-dispersed LDH. |

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.
