Polymer Coatings

Gijsbertus de With has been full professor in materials science at Eindhoven University of Technology (TU/e) since 1995. After graduating from Utrecht University and receiving his PhD in 1977 from Twente University, he joined Philips Research Laboratories, Eindhoven. In 1985 he was appointed part-time professor and in 1995 he became full professor at TU/e. His research interests include structure and interfacial phenomena related to the chemical and thermomechanical behavior of multi-phase materials. He has (co)-authored more than 350 research papers and holds about 15 patents. Throughout he has cooperated with other researchers, both from academia and industry and co-organized the Coatings Science International conferences from 2004 to 2014. In 2006 his two-volume monograph Structure, Deformation, and Integrity of Materials was published, followed by Liquid-state Physical Chemistry in 2013.
