Abstract

ABSTRACT: Manganese dioxide nanoflowers (MnO2 -F) and nanowires (MnO2 -W) are synthesized and MnO2 nanostructures reinforced (0.1 wt.%) epoxy composites are fabricated. The reinforcing effects are studied through tensile, flexural, and impact tests. SEM, TEM, EDAX, XRD, and FTIR characterization techniques are used to understand the interaction between epoxy and the MnO2 nanofiller. It is observed that MnO2 nanostructures have greatly enhanced the mechanical properties of epoxy composites. The tensile strength of EP/MnO2 -F composites has improved by 73%, percentage elongation increased for EP/MnO2 -F composites by 173%, and flexural strength of EP/MnO2 -W has improved by 15%, respectively. Impact strength increased by 35% for EP/MnO2 -F nanocomposites. Graphical abstract: uf0001
