| Abstract | A novel system for enhancing the properties of P(N-isopropylacrylamide-co-poly(ethylene glycol)diacrylate) (P(NIPAM-co-PEGDA)) temperature-sensitive hybrid hydrogels by incorporating acrylolsobutyl polyhedral oligomeric silsesquioxane (MAPOSS) was developed in this study. Inorganic/organic hybrid P(NIPAM-co-PEGDA) hydrogels based on MAPOSS were synthesized via free radical polymerization. Environmental scanning electron microscopy images showed that hydrogels with different feed ratios exhibited significant changes in the porous structure and average pore size. The heterogeneous and irregular network was caused mainly by MAPOSS aggregation. The rigid cage-like nanostructure of MAPOSS had dual opposite effects on polymer thermal properties; this effect was proven through differential scanning calorimetry and thermogravimetric analysis. The mechanical behaviors of the swollen hydrogels investigated through compression test showed that MAPOSS incorporation enhanced the yield strength. Swelling, deswelling and reswelling behaviors of hydrogels with different feed ratios were systematically examined and compared. The increase in MAPOSS provided the hydrogels with improved deswelling rate because of its cage-like nanostructure and hydrophobicity. |

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.
