SDS enhanced Graphene Dispersion in PVA Matrix: Structural, Mechanical, and Conductivity Implications

Abstract This study explores the effect of sodium dodecyl sulphate (SDS) on graphene dispersion in polyvinyl alcohol (PVA) and its impact on the mechanical, electrical, and structural properties of PVA/graphene nanocomposites. FTIR confirmed strong interactions between graphene, PVA, and SDS. Mechanical testing revealed significant improvements in tensile strength and flexibility at the optimal SDS concentration. Electrical conductivity increased notably with higher SDS levels, highlighting the effectiveness of SDS-assisted dispersion. This study offers valuable insights into the role of SDS in shaping the properties of the developed PVA/graphene nanocomposites, which exhibit unique characteristics that make them suitable for flexible electronics applications.
