RESEARCH
Research interests :

The main research focus has been concerned with the synthesis, characterisation, properties
and applications of a broad range of natural and synthetic water soluble polymers.
-Chemical characterisation. We have made considerable advances in determining the
molecular structure of the complex polysaccharide, gum arabic by developing procedures to
fractionate the gum (ion exchange and hydrophobic affinity chromatography) and by
performing alkaline and enzyme hydrolysis studies. We have isolated and characterized a
specific arabinogalactan-protein fraction responsible for the gum's emulsification properties. A
similar approach has more recently been applied to sugar beet pectin which also shows
potential as an food emulsifier.
-Physicochemical characterisation. Studies have included the determination of the
hydrodynamic size, molecular mass and molecular mass distribution of polymers using
dynamic light scattering and gel permeation chromatography coupled with various detectors
(multiangle laser light scattering, photon correlation spectroscopy, refractive index and UV
absorbance) to gain information about the size and shape of macromolecules. A recent
project has involved the development of a new integrated flow field flow fractionation
multiangle laser light scattering system to determine the molecular mass distribution of very
high molecular mass biopolymers and synthetic flocculants.
-Properties of polymer solutions. Novel associative thickeners have been synthesised and
their shear flow and viscoelastic behaviour and interactions with surfactants determined.
Significant progress has been made in the measurement and modelling of the extensional
flow properties of a variety of polymer systems. Polymer conformation (polysaccharide coil-
helix transitions) and gelation mechanisms have been studied using the ESR nitroxide spin
label/spin probe technique and differential scanning calorimetry. This has also enabled
significant progress to be made in understanding the nature of the interactions in mixed
polysaccharide systems and the development of novel gel structures.
-Adsorption of polymers at surfaces. Studies have been undertaken on a wide range of
polymers and substrates. Work has mainly involved determination of adsorption isotherms
and the use of ESR spectroscopy, photon correlation spectroscopy and fluorescence
techniques to monitor the configuration of polymers adsorbed at the solid-liquid interface and
to study polymer/polymer and polymer/surfactant competition. Particular emphasis has been
paid to the effect of adsorbed layer characteristics on the stability and rheological properties
of concentrated suspensions. Significant advances have been made in the understanding of
polyelectrolyte adsorption. Recent work has involved the development of novel food
emulsifiers based on polysaccharide-protein complexes.
-Phase behaviour in polymer/polymer, polymer/particle and polymer/surfactant mixtures. Work
has involved an experimental investigation of the flocculation of particles by non-adsorbed
polymer and the phase behaviour of mixed systems. Phase separation and colloid
aggregation have been explained on a theoretical basis by polymer depletion theories. It has
been demonstrated that liquid –liquid phase separation can be used to separate proteins from
mixtures. Studies have also been undertaken to investigate how phase separation processes
can be exploited in order to produce novel gel structures for food and other applications.
