| Abstract | Inherently conducting polymers have gained increased attention due to the many unique optoelectronic properties they exhibit. The properties of polymers vary depending on the purity, molecular weight distribution, and synthetic conditions; all of these are important for widespread use in many touted applications. These studies have been undertaken in order to separate the low molecular weight and high molecular weight fractions from the crude product. The results demonstrate an efficient separation of different molecular weights of polyaniline (PANI) by the soxhlet extraction procedure with a series of solvents (methanol, chloroform, tetrahydrofuran and benzyl alcohol). The purified products and extracts were characterized by gel permeation chromatography (GPC) to determine their molecular weight distributions. UV-visible, infrared, and nuclear magnetic resonance (NMR) spectroscopy were performed for structural analysis of the polyanilines. Low molecular weight polyanilines can promote the aggregation in polyaniline chains and increase the solubility of polyanilines. |

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.
