Fluorocarbon end-functionalized polymers from poly(arylether) dendritic initiators (2006)
Journal Article
Narrainen, A. P., Hutchings, L., Feast, W., Thompson, R., Ansari, I., & Clarke, N. (2006). Fluorocarbon end-functionalized polymers from poly(arylether) dendritic initiators. Macromolecular Symposia, 231(1), 103-109. https://doi.org/10.1002/masy.200590013

Fréchet-type poly(arylether) first and second generation (G1 and G2 respectively) dendrons were prepared from 1-(bromomethyl)-3,5-bis(trifluoromethyl)benzene. The latter and the brominated versions of the two dendrons were successfully employed in th... Read More about Fluorocarbon end-functionalized polymers from poly(arylether) dendritic initiators.

Novel multi end-functionalised polymers. Additives to modify polymer properties at surfaces and interfaces (2006)
Journal Article
Pillay Narrainen, A., Hutchings, L., Ansari, I., Clarke, N., & Thompson, R. (2006). Novel multi end-functionalised polymers. Additives to modify polymer properties at surfaces and interfaces. Soft Matter, 2(2), 126-128. https://doi.org/10.1039/b516439g

Fréchet-type poly(arylether) dendrons with up to eight trifluoromethyl peripheral groups have been used as initiators in the copper mediated living radical polymerisation of d8-styrene, the surface adsorption behaviour and resulting properties of the...

Surface-active fluorocarbon end-functionalized polylactides (2006)
Journal Article
Hutchings, L., Narrainen, A., Eggleston, S., Clarke, N., & Thompson, R. (2006). Surface-active fluorocarbon end-functionalized polylactides. Polymer, 47(24), 8116-8122. https://doi.org/10.1016/j.polymer.2006.09.050

The synthesis and surface properties of a 2 × C8F17 fluorocarbon di-functionalized poly(d,l-lactide), “F2PLA” are described. Small fractions 5% w/w of F2PLA, when blended with unfunctionalized poly(d,l-lactide), “PLA”, render the surface both hydroph...

In situ water permeation measurement using an external He-3(2+) ion beam (2006)
Journal Article
Clough, A., Collins, S., Gauntlett, F., Hodgson, M., Jeynes, C., Rihawy, M., …Thompson, R. (2006). In situ water permeation measurement using an external He-3(2+) ion beam. Journal of Membrane Science, 285(1-2), 137-143. https://doi.org/10.1016/j.memsci.2006.08.014

A new approach for water vapour transmission rate (WVTR) measurement is demonstrated that uses an external ion beam. ‘Sandwich’ specimens were prepared comprising two films of the barrier material (PET) surrounding a thin film of hydrophilic poly(eth...

Interfacial structure in conjugated polymers: Characterization and control of the interface between poly(9,9-dioctylfluorene) and poly(9,9-dioctylfluorene-alt-benzothiadiazole) (2006)
Journal Article
Higgins, A., Martin, S., Geoghegan, M., Heriot, S., Thompson, R., Cubitt, R., …Jones, R. (2006). Interfacial structure in conjugated polymers: Characterization and control of the interface between poly(9,9-dioctylfluorene) and poly(9,9-dioctylfluorene-alt-benzothiadiazole). Macromolecules, 39(19), 6699-6707. https://doi.org/10.1021/ma060072w

Specular neutron reflectivity and nuclear reaction analysis (NRA) are used to measure the interfacial width between poly(9,9-dioctylfluorene) (F8) and poly(9,9-dioctylfluorene-alt-benzothiadiazole) (F8BT) in a 500 nm bilayer. Annealing at temperature...

Surface adsorption of polar end-functionalised polystyrenes (2006)
Journal Article
Narrainen, A., Clarke, N., Eggleston, S., Hutchings, L., & Thompson, R. (2006). Surface adsorption of polar end-functionalised polystyrenes. Soft Matter, 2(11), 981-985. https://doi.org/10.1039/b608688h

Due to their inherently high surface energy, polar end-functionalised polymers do not normally adsorb to the external surfaces of blends. However, adsorption of polar functionalities can be induced rapidly by annealing in a polar environment such as... Read More about Surface adsorption of polar end-functionalised polystyrenes.
