Abstract: | 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. |
