چکیده انگلیسی
Carbon-based materials are currently at the forefront of materials research due to their outstanding physical, mechanical and electrical properties and exceptional catalytic/electro-catalytic activities. The ability to be dispersed in various polymer matrix leads to a new class of polymer nanocomposites with a wide range of applicability (e.g. food packaging, biosensors, water treatment or drug delivery). The main goal of this study was to provide a facile, rapid, inexpensive way for the green, single-step and large-scale preparation of chitosan/graphene nanomaterial, through electrochemical exfoliation of graphite rods, without the use of any organic solvent. The obtained nanocomposite was characterized from morphological and structural point of view. The X-Ray Diffraction investigation indicates that the obtained material appears as a mixture of few-layer graphene (FLG - 73.75%), multi-layer graphene (MLG - 22.38%) and a small chitosan contribution (3.87%). Furthermore, the applicability of chitosan/graphene-glassy carbon modified electrode for accurate detection and quantification of Sunset Yellow was also reported. As expected, the modified electrode exhibits a wide linear range (2â¯Ãâ¯10â7 - 10â4â¯M) and low detection limit (LODâ¯=â¯6.66â¯Ãâ¯10â8â¯M; S/Nâ¯=â¯3).
