Abstract

The present investigation deals with synthesis of graphene oxide (GO) and fabrication of GO-based hybrid nanocomposites (Ncs). Synthesized GO and Ncs were primarily confirmed by UV visible and Fourier transform infrared (FT-IR) spectroscopy. Fabricated Ncs showed potential antimicrobial activity against Gram-positive and Gram-negative bacterial strains. Surface morphology, Elemental analysis, and FTIR imaging analysis were carried out to confirm Ncs formation. The Ncs were impregnated into the pullulan polymeric layer-by-layer (LbL) ultrathin film by using novel spin-coating approach. Mechanical properties were determined using Brookfield texture analyzer, and percentage moisture content confirmed the physicochemical stability of LbL film.
