| Our research
group is interdisciplinary, consisting of people with different scientific
background such as chemistry, pharmacy, and physics. This group represents a
wide range of research activities. Our research is mainly focused on amphiphilic
polymers, their synthesis,
interaction with surfactants, and
their temperature induced association and
gelation. We are working on both nonionic polymers and on polyelectrolytes, we are also
studying aqueous mixtures of different
polymers. A central theme in our investigations is the relations
between formation, structure and physical features of aqueous systems of
amphiphilic polymers under various conditions. We are continuously looking for
use of these polymers in pharmaceutical applications and to develop materials.
Other areas of research include chemically
cross-linked gels, adsorption and
desorption of polymers on colloidal particles, photochemical-induced changes of
polymers, and shear-induced association
and gelation of biopolymers. We have studied various aspects of
polysaccharides such as ethyl(hydroxyethyl)cellulose,
hydroxyethylcellulose, hyaluronic acid, dextran, chitosan, alginate, and pectin. We are also working on amphiphilic,
thermosensitive block and graft
copolymers, poly(vinyl alcohol),
hydrophobically modified
polymers, and their interactions with cyclodextrins. Primary experimental techniques of investigation involve rheology, static and dynamic light scattering, small angle neutron scattering, gel swelling experiments, asymmetric flow field-flow fractionation and size exclusion chromatography, pulsed gradient spin-echo NMR, and turbidity and cloud point determination. |
