Results of assorted purposeful teams in graphene on the tensile and flexural properties of epoxy nanocomposites: a comparative research: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0


Summary

On this article, we investigated the results of various purposeful teams in graphene on the mechanical efficiency of epoxy nanocomposites fabricated utilizing the in-situ polymerization methodology. This research thought of pristine graphene and three completely different types of functionalized graphene (–NH2, –COOH, and –OH) with various weight % (i.e., 0.25, 0.5, and 1.0 wt%). The purposeful teams grafted of graphene have been confirmed by way of Fourier transforms infrared (FTIR) spectra. Microstructural options and fracture surfaces have been additionally examined by field-emission scanning electron microscopy with energy-dispersive X-ray spectroscopy. Compared to pure epoxy, –OH functionalized graphene/epoxy nanocomposites confirmed a most enchancment of 37.24% in tensile power and 38.05% in flexural power. The improved mechanical properties of epoxy nanocomposites have been attributed to homogeneous dispersion, graphene bridging, and higher interfacial contact between epoxy and graphene.

  • HIGHLIGHTS
  • The impact of pristine and functionalized graphene on the mechanical properties of epoxy nanocomposites was studied.

  • Nanocomposites have been fabricated for 3 completely different wt% (0.25, 0.5, and 1.0) of graphene nanofillers.

  • Discipline emission scanning electron microscopy (FE-SEM) with EDX was used to look at the microstructural options of fractured surfaces.

  • Graphene enhanced the mechanical properties of epoxy nanocomposites.
