Structure-property relations in polysulfones
Polysulfones are a class of amorphous polymers exhibiting high glass transition temperatures and excellent mechanical properties. Some examples of applications are medical devices, aircraft interior parts, pipes and fittings, industrial flow meters, microwave cookware and gas separation membranes. In spite of a comparable backbone structure there are differences in the mechanical properties which are still not fully understood. Goal of this project is to study the relation between the intrinsic materials response and their short-term (impact) and their long-term (fatigue) performance, taking also processing in account. An experimental/numerical framework is used employing the Eindhoven Glassy Polymer constitutive model. An attempt will be made to relate both experimental results as well as model parameters to molecular architecture.
Type of research: experimental/numerical
