| Abstract | A facile strategy for preparation of alkyne-functionalized cellulose fibers with click reactivity is reported herein. Poly(3-ethynylaniline) [poly(3-EA)] with pendant alkynyl groups was obtained by chemical oxidation polymerization of 3-ethynylaniline with ammonium persulfate in low-concentration hydrochloric acid solution at ice-bath temperature and used to generate alkyne-functionalized cellulose fibers in situ from pulp fibres. Successful preparation of alkyne-functionalized cellulose fibers was confirmed by attenuated total reflectance Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy. The effects of process variables on poly(3-EA) deposition and fiber loss were investigated, and suitable preparation conditions identified. Deposition of poly(3-EA) did not change the crystallinity or hydrophilicity of the cellulose fibers. Poly(3-EA) and alkyne-functionalized cellulose fibers reacted with azides by Cu(I)-catalyzed alkyne–azide 1,3-dipolar cycloaddition. Thus, this in situ chemical polymerization technology provides a new platform for click functionalization of cellulose fibers. Applications of cellulose fibers produced in this way are limited to those without demanding requirements in terms of product strength or color. |

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.
