| Abstract | Bio-based degradable plastic is superior to petroleum-based plastic in terms of environmental protection and preservation of resources. A novel cross-linking system using tributyl citrate (TBC) as a cross-linking agent was used to create a bio-based degradable plastic via acetylation modified starch acetate (SA) and cellulose acetate (CA). Fourier transform infrared spectroscopy of the new plastic films revealed that a cross-Claisen ester condensation reaction had indeed occurred among TBC, CA and SA in the cross-linking system. Thermogravimetric analysis, X-ray diffraction, Scanning electron microscopy and mechanical properties tests confirmed that the fabricated films had mechanical properties and thermal stability that were comparable to conventional plastic films. A degradation-in-soil test showed that the fabricated films have controllable biodegradation properties by adjusting the amount of SA added. The tensile stress of two films—one with mass ratio of SA to CA1:3 and the other with mass ratio of 2:3—reached 3.5 and 3.0 MPa, respectively, the corresponding tensile strains were 22.3 and 17.9 %. The highest thermal stability temperature for both films was 205 °C. After being buried in soil for 35 days, the first film was 36 % degraded, and the second film was 41 % degraded. This paper is expected to promote the study and fabricate of bio-based degradable plastic film. |

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.
