| Abstract | Montmorillonite (MMT) and titanate nanotube (TNT) based coatings have been prepared through a layer-by-layer self-assembly method, in order to enhance the thermal and thermal-oxidative stability, flame retardancy and ultraviolet protection of polyethylene terephthalate (PET) fabric. To fabricate these coatings, positively charged chitosan was chosen to cooperate with negatively charged MMT and TNTs. X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy demonstrated that these coatings can be successfully constructed on the substrates. The synergistic effects of MMT and TNT based hybrid coatings were investigated by thermogravimetric analysis (TGA), cone calorimetry and ultraviolet transmission spectroscopy. TGA results showed that the char residue was improved obviously after the sample was covered with the hybrid coating. Furthermore, 4 quadlayers chitosan/MMT/chitosan/TNTs coating significantly improved the fire resistance of PET fabric, as evidenced by the obvious reduction (48% and 36%) of peak heat release rate and total heat release compared with those of the pure PET fabric, respectively. Meanwhile, the hybrid coating modified PET fabrics possessed an improved ultraviolet protection. |

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.
