Project

Dielectric relaxations in H-bonding, supramolecular polymers and organic ferroelectrics

Supramolecular (reversible) polymers formed by self association of bi- or tri-functional monomers based on quadruple hydrogen bonds exhibit viscoelastic properties being characteristic for molecular mass macromolecules. This project focuses on the molecular and cooperative dynamics of polymers containing quadruple hydrogen bonding units (2-ureido-4[1H]-pyrimidinone = UPy) by means of broadband dielectric spectroscopy (DRS). Various polymer architectures will be studied, ranging from fully self-assembled linear or X-linked supramolecular polymers via UPy-bonded macromonomers to partially reversibly X-linked networks. The project will be realized in close collaboration with the group of Prof. Sijbesma at the TU Eindhoven (The Netherlands).
