A series of hydrogenous and deuterated four-arm polystyrene stars with low polydispersity have been synthesized by anionic polymerization. Self-diffusion data have been obtained using helium-3 nuclear reaction analysis, and rheology has been employed...

Solvent accelerated polymer diffusion in thin films (2005)
Journal Article
Thompson, R., McDonald, M., Lenthall, J., & Hutchings, L. (2005). Solvent accelerated polymer diffusion in thin films. Macromolecules, 38(10), 4339-4344. https://doi.org/10.1021/ma050317p

We have investigated the absorption of cyclohexane vapor into polystyrene films and the resulting polymer interdiffusion that is enabled by this process. The swelling of films due to solvent absorption was relatively insensitive to the film thickness... Read More about Solvent accelerated polymer diffusion in thin films.

Surface segregation and self-stratification in blends of spin-cast polyfluorene derivatives (2005)
Journal Article
Higgins, A., Martin, S., Thompson, R., Chappell, J., Voigt, M., Lidzey, D., …Geoghegan, M. (2005). Surface segregation and self-stratification in blends of spin-cast polyfluorene derivatives. Journal of Physics: Condensed Matter, 17(8), 1319-1328

We have used helium-3 nuclear reaction analysis to study the morphology of spin-cast blends of poly(9,9'-dioctylfluorene) (178) and poly(9,9'-dioctylfluorene-alt-benzothiadiazole) as a function of composition, casting solvent, and initial solvent con...

Solvent vapor mediated polymer adsorption in thin films (2004)
Journal Article
Kiff, F., Richards, R., & Thompson, R. (2004). Solvent vapor mediated polymer adsorption in thin films. Langmuir, 20(11), 4465-4470. https://doi.org/10.1021/la035825b

The effectiveness of a "solvent annealing" process was investigated for thin (similar to150 nm) polystyrene films, in which the diffusion and reorganization of polymer chains were mediated by the controlled absorption of cyclohexane vapor. Results we... Read More about Solvent vapor mediated polymer adsorption in thin films.

Correlating structure with fluorescence emission in phase-separated conjugated-polymer blends (2003)
Journal Article
Chappell, J., Lidzey, D., Jukes, P., Higgins, A., Thompson, R., O'Connor, S., …Jones, R. (2003). Correlating structure with fluorescence emission in phase-separated conjugated-polymer blends. Nature Materials, 2(9), 616-621

Blends of conjugated polymers are frequently used as the active semiconducting layer in light-emitting diodes and photovoltaic devices. Here we report the use of scanning near-field optical microscopy, scanning force microscopy and nuclear-reaction a...

Film thickness effects on the distribution of high-molecular-weight heterotelechelic polymers (2002)
Journal Article
Hutchings, L., Richards, R., Thompson, R., & Bucknall, D. (2002). Film thickness effects on the distribution of high-molecular-weight heterotelechelic polymers. The European Physical Journal E, 8(2), 121-128

High-molecular-weight heterotelechelic deuteriopolystyrene, NDPSF, possessing an amine functional group at one end of the chain and a fluorocarbon group at the other was tethered to a silicon substrate by its amine functional group. These layers were... Read More about Film thickness effects on the distribution of high-molecular-weight heterotelechelic polymers.

Interface development in polycarbonate/poly(methyl methacrylate) bilayer films (2001)
Journal Article

We report the effect of annealing over a range of temperatures and times on the mixing, stability, and interfacial width in thin bilayer films of bisphenol A-polycarbonate (PC) on deuterated poly(methyl methacrylate) (dPMMA). These bilayer films were... Read More about Interface development in polycarbonate/poly(methyl methacrylate) bilayer films.

Small-angle neutron scattering from single arm labeled polybutadiene star polymers in dilute solution (2001)

Dilute cyclohexane solutions of polybutadiene star polymers with 3, 4, 8, and 12 arms wherein one arm is perdeuterated have been investigated by small-angle neutron scattering. The scattering cross sections obtained showed a characteristic peak at fi... Read More about Small-angle neutron scattering from single arm labeled polybutadiene star polymers in dilute solution.
