Epoxy resin K-153A and poly(propylene glycol) diglycidyl ether/graphene oxide polymer composite based for properties enhancement

Abstract

This article introduces the effects of graphene oxide (GO) content on some properties of a composite based on the blend of epoxy resin K-153A and poly(propylene glycol) diglycidyl ether, the blend is hardened with polyethylene polyamine (PEPA). Epoxy resin K-153A is a product of ED-20 epoxy resin modified with oligomer acrylate of MGF-9 and thiokol. Tensile strength of polymer composite with 1.5 wt% of GO is 86.65 MPa and flexural strength of the polymer composite is 105.56 MPa the values are much higher than that of K-153A/ Poly(propylene glycol) diglycidyl ether blend are 68.42 MPa and 79.56 Mpa, respectively. Thermal oxidation resistance polymer composite also increases in comparison to those of K-153A epoxy resin/ Poly(propylene glycol) diglycidyl ether blend.
