| Abstract | In situ reaction of various long chain hydrocarbon precursors with cellulosic substrate inside plasma zone were investigated. Each of the selected precursor compounds had C12 alkyl chain as the hydrophobic moiety to impart hydrophobicity to the substrate and a functional group to aid reaction with the active sites of the substrate. The selected compounds were dodecyl acrylate (DA, with acrylate group), lauryl alcohol (LA, with hydroxyl group), dodecanoic acid (DODAC, with carboxylic acid) and dodecane (DD, without any functional group). Treatment was carried out in-situ with these compounds using helium gas as a carrier. After the treatment, durable hydrophobicity was obtained in all cases with water absorbency time of substrate increasing to >1 h in the case of DA and LA, up to 20 min in the case of DD and only up to 9 min in the case of DODAC. The functional groups were found to have profound effect on the extent of functionality obtained and the plasma parameters required to obtain effective reaction with the substrate. Both plasma zone and the functionalized surfaces were characterized to understand the chemistry involved with the different precursors. |

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.
