Enhanced mechanical properties of silica nanoparticles-covered cross-linking graphene oxide filled thermoplastic polyurethane composite

Abstract

In this work, silica nanoparticles-covered cross-linking graphene oxide (GOES) are successfully synthesized in the stacking graphene oxide (GOE) solution, ethylenediamine (EDA) is used to simultaneous reduction, functionalization the graphene oxide (GO). The GOES filled thermoplastic polyurethane (TPU) composites are prepared through solution mixing. The mechanical properties of GOES/TPU are systematically investigated. The results reveal that the properties of composites filled with the cross-linked (GOE, GOES) filler are higher than those un-cross-linked (GO, GOS) filler. Furthermore, when the loading of 2 wt %, the tensile strength and the tensile strain of GOES/TPU composites significantly enhanced (48.9 MPa, 2140 %), as compared to the pure TPU (30.6 MPa, 1370 %). The improvement in mechanical properties of GOES/TPU is attributed to the homogeneous dispersion of GOES in the TPU matrix and the strong interfacial interaction between them.
