Abstract
Humanity is under sustained pressure to reduce energy consumption, reduce waste disposal and increase the use of renewable materials. Functional nanomaterials based on renewable resources have the potential to deliver a holistic solution by increasing activity, reducing the use of depletable resources, reducing CO2 emissions, and reducing waste at their end-of-life. To support this development, investigate a range of surface functionalization pathways to introduce ionic groups, small molecules and polymers as well as metal nanoparticles. The thermodynamic interactions and kinetics assembly of these nanoparticles is studied, on their own or with polymers or other nanoparticles, to make higher order structures such as organized films, membranes, hydrogels and aerogels. In this talk, Prof. Thielemans will give an overview of his research on the interactions at nanocellulose surfaces, the kinetics of assembly of nanocellulose into higher order structures, and recent work on the visualization of the chiral nematic phase of cellulose nanocrystals in liquid form using second harmonic generation microscopy.
