Our Series 7 of OCCA Weekly Webinars continues with "Nanostructural Analysis of Coatings using AFM-IR" presented by Dr Suzanne Morsch of University of Manchester. The webinar will take place via Zoom on Wednesday 18 May at 2:30pm.This webinar is free to attend, simply register below and you'll receive further details & joining instructions in due course.


The development and commercialisation of AFM-IR in the past decade has allowed infrared characterisation of organic materials to be performed at the nanoscale. This means that functional group chemistry can, for the first time, be mapped with sub-diffraction limit resolution, under ambient conditions. This talk will focus on the application of this exciting technique in field of protective coatings. Specific examples include the use of AFM-IR chemical mapping to confirm historically disputed internal nanostructure within epoxy resins (‘nodules’), where local chemistry is shown to be consistent with fluctuations in cross-linking density. In-situ experiments under variable humidity will also be presented, where heterogeneous water uptake into can coatings is mapped. Finally, direct analysis of chemical gradients in the epoxy-amine interphase is contrasted to the use of ATR-FTIR and the ‘thin film’ approach. The use AFM-IR to interrogate the interphase directly is shown to generate more accurate insights into the formation, extent and degradation of these conventionally inaccessible regions.   

Speaker Profile

Dr Suzanne Morsch - Research Fellow, University of Manchester

Dr Suzanne Morsch obtained her PhD in Surface Science from the University of Durham in 2013. Since then, she has worked as a Research Associate, and more recently Research Fellow at the AkzoNobel Laboratory for Corrosion Protection in the Department of Materials at the University of Manchester, focused on the mechanisms of polymer degradation in protective paints, with an emphasis on nanostructural analysis using AFM-IR.
