An off-specular neutron scattering study of the 'peristaltic mode' in the dew...
We plan to use the OFFSPEC SPIN-Echo reflectometer to study the mechanism of the 'peristaltic mode' in the spinodal dewetting of thin polymer films. In the peristaltic mode the... -
The interpenetration of two poly(ethylene oxide) polymer brushes under confin...
Coating two surfaces with polymer brushes has been shown on many occasions to reduce friction by orders of magnitude. These ultra-low frictions are believed to stem from be the... -
Polymerisation of Styrene in PEI-Surfactant Films on Si Wafers
We have been studying the formation of solid polymer-surfactant films formed from cationic surfactants with PEI. We wish to use the highly organised mesostructures formed in the... -
Latex - structure in binary mixtures - studies of crystallisation and stability
Recent experiments on SANS2D have indicated that small colloidal particles can act as macroions that screen the charged interactions of larger particles. This can cause changes... -
Structure of Colloidal Crystals Near a Solid Surface
The structure of colloidal crystals (dispersions of particles that spontaneously order in a regular array) is known to be influenced by solid boundaries. However there are few... -
Surfactant chain length effects on styrene incorporation in PEI/surfactant films
We have been studying the formation of solid polymer-surfactant films at the air-solution interface formed from cationic surfactants with PEI. We wish to use the highly... -
Order in the bulk and at the surface of dispersions of colloidal particles
Highly ordered dispersions of charged polymer particles that are tens or hundreds of nanometres diameter can be prepared. These are useful model systems for self-assembly and... -
Polystyrene latex - 'single crystal' structure studies and melting under flow
For deionised, charge stabilised latices, there has been some uncertainty about the stacking sequence of close packed layers in samples at equilibrium. The ABCA stacking in... -
Encapsulation of monomers in cationic surfactant-polymer solutions
We have been studying the solution interactions leading to formation of solid polymer-surfactant films at the air-solution interface. We wish to use the mesostructures in the... -
Amide monolayers at the polymer melt air interface
This proposal seeks to identify and characterise the adsorption of primary linear amides that adsorb to the surface from the bulk of a polymer melt. These layers are... -
Core-Shell Melt Electrospun Fibres
Electrospinning is a technique that produces nanoscale to microscale sized polymer fibre from solution and the molten state. We have previously used small angle neutron... -
Encapsulation of monomers in cationic surfactant-polymer films
We have been studying the formation of solid polymer-surfactant films at the air-solution interface formed from cationic surfactants with PEI. We wish to use the highly... -
Compatibilisation of polymer blends using electrospinning
This proposal seachs time to establish the conditions under which electrospinning can be used to provide (non-equilibrium) mixtures of immiscible polymers. Such an outcome might... -
Non-equilibrium kinetics in highly interacting polymer mixtures
We seek to investigate the non-equilibrium phenomena of a model polymer mixture by time-solved SANS and temperature jump experiments within (a) one-phase region and (b) one to...
