Exploiting graphene’s exceptional physical properties in polymer composites is a significant challenge because of the difficulty in controlling the graphene conformation and dispersion. Reliable processing of graphene polymer composites with uniform... Read More about Controlled Structure Evolution of Graphene Networks in Polymer Composites.

Distortion of Chain Conformation and Reduced Entanglement in Polymer–Graphene Oxide Nanocomposites (2016)
Journal Article
Weir, M., Johnson, D., Boothroyd, S., Savage, R., Thompson, R., King, S., …Clarke, N. (2016). Distortion of Chain Conformation and Reduced Entanglement in Polymer–Graphene Oxide Nanocomposites. ACS Macro Letters, 5(4), 430-434. https://doi.org/10.1021/acsmacrolett.6b00100

We study the conformations of polymer chains in polymer–graphene oxide nanocomposites. We show that the chains have a reduced radius of gyration that is consistent with confinement at a solid interface in the melt, as is expected for well-dispersed,...

We study the conformation of graphene oxide as the filler in nanocomposites of polystyrene and poly(methyl methacrylate) using inverse-space scattering techniques and atomic force microscopy. By subtracting the polymer scattering to estimate the scat... Read More about Extrinsic Wrinkling and Single Exfoliated Sheets of Graphene Oxide in Polymer Composites.
