Preparation and properties of novel polymer nano- (and larger) particles by heterogeneous
polymerization (emulsion, dispersion, and suspension polymerization).
Applications of polymer particles in advanced systems,
such as nanocomposites, biomedical applications, and solid supported
Application of carbon nanotubes and nanofibers in advanced structural
Kinetics and mechanisms of emusion and suspension polymerization.
Particle formation, particle growth, stabilizing mechanisms and
Synthesis and characterization of surface active and/or associating
Conformation, nanostructure, dynamics and viscoeastic properties of
associating polymers in solution. Central experimental techniques are static
and dynamic light scattering, NMR-diffusion and rheology.
Surface chemistry includes:
Biological surfaces, and drugs. Bioactive molacules on surfaces. Adhesion in polymer/polymer and composite systems. Surface
modification techniques and surface analysis by contact angles, XPS, electron
micrsoscopy, etc., and the mesurement of diffusion processes relevant to
adhesion. The objective is to understand adsorption and adhesion mechanisms and to control
adhesion in composite systems.
Instrumentation for the measurement of interfacial tension and
surface dilatational rheology by drop shape analysis (DROP Instrument). This instrumentation is used in the following research areas:
Conformation and dynamics of monomolecular polymer films
(synthetic and natural polymers) at the air/water and oil/water
interface. Measurements of surface elasticity and viscosity by the
oscillating drop and pulsed ralaxation.
Kinetics for adsorption and phase transfer of surface active
substances between water and organic phases measured by dynamic surface tension.
The use of contact angles for surface energy measurements in
connection to surface modification and contact angle hysteresis in
connetion to sliding friction.
of research is to improve the understanding of chemical and physical mechanisms
that are important for the preparation and use of polymer colloids, and develop
new or improved products and processes of practical importance.
