| Abstract | We report a facile fabrication of free standing, highly conducting flexible reduced graphene oxide (rGO) paper by an evaporation-induced self-assembly process. The impact of heat treatment conditions on the structural, mechanical and electrical properties of rGO paper has been investigated. The effect of annealing temperature on the structural variations of GO (graphene oxide) and rGO papers was confirmed by X-ray diffraction studies. The removal of oxygen and other functional groups from the GO paper by heat-treatment process was confirmed using FTIR analysis. Raman spectra confirmed the effective control of defects in rGO paper by means of heat-treatment, which has also been inferred from the Raman mapping analysis. The morphology of rGO paper studied by FESEM emphasized the stacking of rGO layers. The electrical conductivity was significantly enhanced for 400 °C heat-treated rGO paper (4.82 × 10$^{3}$ S/cm) compared to the as-prepared GO paper (7 × 10$^{−3}$ S/cm). The tensile strength of the rGO paper was also relatively higher than that of GO paper. The experimental results demonstrated that the present approach is simple and reducing agent free green approach for preparing large-area rGO paper with high electrical conductivity and mechanical flexibility. |

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.
