Abstract

Graphene was successfully synthesized from chicken feather biomass waste using the Liquid Phase Exfoliation (LPE) method assisted by Linear Alkylbenzene Sulfonate (LAS) surfactant at varying volumes of 1 mL, 1.5 mL, and 2 mL. The aim of this study was to evaluate the potential of chicken feather-derived graphene as an electrode material for rechargeable batteries. Characterization using UV-Visible spectrophotometry showed a distinct absorption peak at approximately 270 nm, corresponding to the π→π* electronic transition, with increasing absorbance intensity observed with higher surfactant volumes, indicating more effective graphene exfoliation. XRD analysis revealed a shift in diffraction peaks to lower 2 angles, increased interlayer spacing (d-spacing), and the largest crystallite size of 13.58 nm at a surfactant volume of 1.5 mL. These results indicate that the surfactant plays a critical role in stabilizing and forming the crystalline structure of graphene. Overall, this study demonstrates that chicken feather-based graphene has promising potential to be developed as an eco-friendly electrode material in rechargeable battery applications
