Konstruktionsmaterial
The processing of soft matter into products typically involves rheologically complex fluids in complex flow configurations. Thus, understanding flow-field-matter/compositional interactions in relation to fundamental rheological properties is essential for obtaining products with favorable performance.In this framework, the staples of Roland's research and current related activities and interests are:(i) Advanced characterization methods, method development - focused on nonlinear material characterization and hyphenated rheological techniques, e.g. rheo-microscopy, rheo-SAXS, mainly applied to nanocellulose suspensions, polymer nanocomposites, adhesives and biomaterials (biofilms, tissues).(ii) Tailoring multifunctional properties in nanostructured materials - focused on the process structuring of polymer nanocomposites based on graphene and other high aspect ratio fillers for enhanced electrical, antibacterial, thermal, mechanical, gas-barrier etc. properties.(iii) Dynamics of simple and complex fluids for processing applications - focused on modeling, processing flow and compositional optimization of high filler content bicomposites and flow-assisted structuring of nanocrystalline cellulose dispersions.Roland is PI in the Wallenberg Wood Science Centre (WWSC 2.0) and the Vinnova Competence Centre '2D material-based technology for industrial applications' (2D-TECH). In addition to his activities at Chalmers, Roland is Editor of the Annual Transactions of the Nordic Rheology Society.
