John Klier

Professor & Department Head

Research interests include (a) surfactant & polymeric surfactant assembly and association, synthesis, structure and properties of polymer colloids and functional polymers and polymer functionalization and (b) applying these unique materials to addressing key unmet needs in industrial and biological applications including novel coatings and adhesives, delivery systems and devices via collaborations with industrial, academic and governmental partners.

Current Research

- New monomers for surface functionalization, emulsion polymerization and crosslinking
- Mechanically actuated crosslinking of gels and polymers
- Novel colloidal delivery systems for cancer therapeutics
- Coatings with enhanced properties via pigment encapsulation and segragation
- Surface functionalization of low energy polymers for adhesion and other applications
- Synthesis of novel asymmetric colloids for electronic and biological applications
- Fabrication of micro heterogeneous polymer films, fibers and articles for advanced controlled release applciations
