The growing need for sustainable and eco-friendly materials has driven extensive re-search on green polymer nanocomposites. Among various biopolymers, chitosan (CS) has emerged as a promising candidate due to its biodegradability, renewability, and film-forming ability. When reinforced with multi-walled carbon nanotubes (MWCNTs), chitosan-based nanocomposites exhibit enhanced structural and electrical potential, making them suitable for environmental and sensing applications. This study focuses on the synthesis and structural characterization of CS/MWCNT nanocomposites to explore their potential for sustainable conductive material-related applications. In the present work, green polymer nanocomposites reinforced with multi-walled carbon nanotubes synthesized from three different carbon sources were prepared. Qualitative dispersion behavior of CNTs in the chitosan matrix was evaluated through visual observation dur-ing the preparation process. Structural analysis based on X-ray diffraction (XRD) con-firmed the successful incorporation of carbon nanotubes into the chitosan matrix and revealed a reduction in chitosan crystallinity due to physical interactions and polymer chain wrapping. These findings demonstrate that MWCNT-reinforced chitosan biopoly-mer nanocomposites offer promising potential for applications in sustainable conduc-tive materials and green electronic systems.
