Our Polymers & Microfluidics group is centred on experimental soft condensed matter. We study complex fluids, often multicomponent systems, containing polymers, copolymers, (nano)-particles and surfactants. Microfluidics provides unique opportunities to synthesise, formulate, process and analyse fluids and is therefore explored in our work.
Additionally, we employ extensively scattering (light, X-rays and neutrons), microscopy, calorimetry and spectroscopy - but we also develop our own measurement tools. Particularly, we resort to novel combinatorial and high-throughput techniques to address problems with large parameter space where conventional experimentation becomes unfeasible. We have developped novel nano and microfabrication approaches using frontal photopolymerisation and self-assembly, with applications in microfluidics, functional and responsive materials.
Combinatorial polymer mixture (PS/PB) library and sequential 2D scattering pattern during spinodal decomposition.
Fluid thread breakup under microfluidic confinement with applications in oil recovery and biology.
Nano/micro-surface patterns, with tuneable amplitude, wavelength and topography (spinodal shown here), are readily induced by plasma oxidation and simultaneous multi-axial strain of elastomer membranes.
