Zeta Potential Measurements in Polymer Research

In many applications of polymer materials, as e.g. coatings, composites or as smart surfaces, the material properties or the adhesion to other substances are determined to a great amount by functional groups situated at the very surface. While contact angle measurements can reveal the polarity of a surface, the zeta potential (the electrical potential of a solid in contact to an aqueous solution) gives valuable information about its acid-base behaviour resulting from charged functional groups, the adsorption of ions and molecules, and time-dependent processes as swelling and chemical reactions. In this free webinar, Dr. Drechsler will: – Introduce basic principles of electrokinetic measurements used to determine the zeta potential of samples of different size and geometry. – Present examples of polymer surface characterization by zeta potential measurements in combination with other surface-sensitive methods. – Discuss practical problems in the implementation and analysis of zeta potential measurement.
