Analogy and Comparative Study of Hydroxypropyl Methylcellulose
(HPMC) Biopolymer with Graphene Oxide and Zinc Oxide Nano Fillers

Present study describes the analogy and comparative study of polymer nanocomposites with the known
polymer matrix hydroxypropyl methylcellulose (HPMC) incorporated with graphene oxide (GO) and
zinc oxide (ZnO) nanoparticles as nano fillers. The polymer nanocomposite films were carried out
using solution casting method and characterized by IR spectroscopy, XRD analysis, mechanical
properties, thermal characterization and optical microscopy analysis. There were several changes in
the HPMC polymer by the addition of nanoparticles of GO and ZnO in structural, thermal, mechanical
and optical properties. The thermal stability of the composite films increased as compared with the
pure HPMC whereas the mechanical study shows a variation of down values.
