Polymer Colloids Research Interests and Expertise

Nanoparticles and Nanomaterials.

• Film formation of two-phase nanoparticles and inorganic / organic nanocomposites.
  
• Structure / property relationships in nanocomposite films made from nanoparticles.
• Film formation of waterborne pressure-sensitive adhesives, studied on the nanoscale.

Use and development of techniques of physical characterization of polymer colloid surfaces and interfaces.

Physical characterization of latex.

• Investigation of film formation mechanisms.
• Studies of morphological development.
• Measurements of surface roughness.
• Optical properties.
• Surfactant transport and segregation.

Studies of polymer/water interfaces.

• Surfactant adsorption and conformation.
• Polymer swelling.
• Chain conformation of hydrophilic/hydrophobic polymers.
• Polymeric surfactants.

Magnetic resonance imaging of polymer colloids - to determine spatial and temporal information about:

• Phase separation.
• Cross-linking reactions.
• Particle size.
• Restricted diffusion.
