Fluid dynamic induced break-up during volcanic eruptions (2019)
Journal Article
Jones, T., Reynolds, C., & Boothroyd, S. (2019). Fluid dynamic induced break-up during volcanic eruptions. Nature Communications, 10, Article 3828. https://doi.org/10.1038/s41467-019-11750-4

Determining whether magma fragments during eruption remains a seminal challenge in volcanology. There is a robust paradigm for fragmentation of high viscosity, silicic magmas, however little is known about the fragmentation behaviour of lower viscosi...

Association and Relaxation of Supra-Macromolecular Polymers (2019)
Journal Article
Boothroyd, S., Hoyle, D., McLeish, T., Munch, E., Schach, R., Smith, A., & Thompson, R. (2019). Association and Relaxation of Supra-Macromolecular Polymers. Soft Matter, 15(26), 5296-5307. https://doi.org/10.1039/c8sm02580k

This paper describes the structures created by assembling functionalised entangled polymers and the effect these have on the rheology of the material. A polybutadiene (PBd) linear polymer precursor of sufficient molecular weight to be entangled is us... Read More about Association and Relaxation of Supra-Macromolecular Polymers.

Controlled Structure Evolution of Graphene Networks in Polymer Composites (2018)
Journal Article
Boothroyd, S. C., Johnson, D. W., Weir, M. P., Reynolds, C. D., Hart, J. M., Smith, A. J., …Coleman, K. S. (2018). Controlled Structure Evolution of Graphene Networks in Polymer Composites. Chemistry of Materials, 30(5), 1524-1531. https://doi.org/10.1021/acs.chemmater.7b04343

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,...

Extrinsic Wrinkling and Single Exfoliated Sheets of Graphene Oxide in Polymer Composites (2016)
Journal Article
Weir, M. P., Johnson, D. W., Boothroyd, S. C., Savage, R. C., Thompson, R. L., Parnell, S. R., …Clarke, N. (2016). Extrinsic Wrinkling and Single Exfoliated Sheets of Graphene Oxide in Polymer Composites. Chemistry of Materials, 28(6), 1698-1704. https://doi.org/10.1021/acs.chemmater.5b04502

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.

A facile route for rubber breakdown via cross metathesis reactions (2016)
Journal Article
Smith, R., Boothroyd, S., Khosravi, E., & Thompson, R. (2016). A facile route for rubber breakdown via cross metathesis reactions. Green Chemistry, 18(11), 3448-3455. https://doi.org/10.1039/c5gc03075g

A new approach towards reprocessing cross-linked rubbery materials by catalytic disassembly of polymer chains, which eliminates the need for energy intensive mechanical processes, is demonstrated. First and second generation (G1 and G2) Grubbs’ ruthe... Read More about A facile route for rubber breakdown via cross metathesis reactions.
