Design, synthesis, and characterization of polymers and nanostructured materials capable of controlled-assembly, tethering, and self-organization in ultrathin films. This includes functional macromolecules, coordination polymerization, polymerization on surfaces, electropolymerization, and preparation of nanoparticles and hybrid materials. Properties include: smart coatings, electrically conducting, photoluminescent, electroluminescent, energy harvesting, optically active, and biocompatible. Surface sensitive spectroscopy and microscopy is systematically utilized to probe materials properties and biological phenomena. We are also involved in investigating nanoparticles, nanostructured surfaces, and nanocomposite materials for sensor and bioapplications. Other applied studies include packaging, coatings, biomaterials, plastics, and process development.

Dr. Gelling is a Technical Director in Performance Coatings at The Valspar Corporation in Minneapolis, MN. Before her time at Valspar, she was an Associate Professor in the Department of Coatings and Polymeric Materials at North Dakota State University. She gained a B.S. in Chemistry at the University of North Dakota then completed a doctorate in Chemistry at North Dakota State University. Her principal research interests are the use of electrochemistry to monitor the health and degradation of polymeric materials and the transitioning of laboratory electrochemical techniques to the field. During her career, she has studied various coating systems from the traditional to the novel, such as electroactive conducting polymers. She has experience with numerous lightweight metal alloys from her research concentrating on aluminum and magnesium corrosion inhibition; focusing on environmentally compliant non-chromate coatings.
Electrochemical Investigations in the Development of High Performance Coatings
Historically, corrosion and coatings research has been a visual study. A survey of ASTM methods for corrosion detection of coated surfaces illustrates the emphasis on the visual assessment of corrosion detection. For example, in ASTM B117 (Standard Test Method of Salt Spray Testing), one of the most widely used corrosion experiments, many users visually interpret scribe creepage or blister density.
Electrochemical techniques have been utilized in the past few decades as important methods in the study of corrosion and coating degradation. Electrochemical techniques allow for the determination of changes in material properties, which often occur prior to visual changes and provide information regarding corrosion mechanisms. Indeed, by using these techniques, such as Electrochemical Impedance Spectroscopy (EIS), Scanning Electrochemical Microscopy (SECM), and Scanning Vibrating Electrode Technique (SVET), important mechanistic information regarding protection/failure transitions can be determined.
EIS, SECM, SVET, along with the many other electrochemical techniques, provide information that is far superior to the historical visual corrosion assessment. For example, small changes in capacitance and resistance of a coated sample can be monitored via EIS and small current densities resulting from corrosion redox reactions can be measured via SVET. The changes is capacitance and resistance determined via EIS can occur due to water ingress as well as changes in barrier protection. The current densities measured by SVET can provide a quantitative measurement of the rate of corrosion.
During the presentation, a review of electrochemical techniques for corrosion and material degradation assessment will be provided along with real-world results of the use of those techniques to study a next generation powder coating.
