Synthesis and Characterization of Graphene Oxide/Poly (2-ethyl-2-oxazoline) Composites

Abstract

Graphene oxide/poly (2-ethyl-2-oxazoline) (GO/PEOX) nanocomposites were fabricated via solution mixing technique. The chemical structure and morphology of the nanocomposites were investigated using FTIR, XRD, TGA, FESEM, EDX and HRTEM. Microscopic and XRD measurements demonstrated that the GO nanosheets were uniformly dispersed in the PEOX matrix. FTIR spectra revealed that the PEOX was noncovalently grafted to the GO surfaces. Furthermore, the incorporation of GO greatly improved the thermal stability of PEOX possibly due to the high aspect ratio and uniform dispersion of GO nanosheets in the PEOX matrix.
