Department of Supramolecular Polymer Systems


Head: Petr Štěpánek, PhD
(phone +420-296 809 211, e-mail stepan@imc.cas.cz)

ResearchThe activities of the Department are focused on physical and physicochemical studies of various supramolecular systems consisting of homopolymers, block and random copolymers, gels, either in bulk or in the presence of large or small amounts of solvents or solvent mixtures, or latices. Particular attention is paid to phase separation phenomena, to association, complexation and micelle formation, to ordering processes on microscopic, mesoscopic and macroscopic scales with respect to their kinetics and dynamics, and to the generated structure and its flow behavior. Research is performed in the field of organic electroluminescence (polymer light-emitting devices - LEDs) and of optical, electric and photoelectric properties of thin polymer films. The experimental techniques used include static and dynamic light scattering, time-resolved light scattering, laser speckle analysis, birefringence analysis, image analysis, electron paramagnetic resonance (EPR), both stationary and time-resolved fluorescence, measurements of electroluminescence and photoconductivity, Newtonian and non-Newtonian viscometry, electrorheology, size exclusion chromatography with multiple detection, and MALDI-TOF mass spectrometry.
