Microstructure and elastic tensile behavior of polyethylene terephthalate-exfoliated graphene nanocomposites



Polyethylene terephthalate-exfoliated graphene nanocomposites were prepared by injection molding. Nanocomposites with graphene platelets of 2, 5, 10, and 15% weight fractions were molded and tested for mechanical characterization. Transmission electron microscopy imaging along with X-ray diffraction show that the graphene platelets remained intact and were dispersed into the matrix. An exponential increase in the Young’s modulus of the nanocomposites was observed, but with current limits on exfoliation they do not yet reach the potential suggested by idealized predictions.

We acknowledge XG Sciences for providing xGnP-M-5 grade nanoplatelets and Oviation Polymers for compounding and injection molding of the samples. We also, acknowledge Mr. Terry Colberg, OSU Microscopy Lab, for his help with microtome and TEM imaging and Au/Pt coating of samples for SEM. This work is part of an industry sponsored research program at Oklahoma State University.
