16. Design of renewable and functional polyamides and polyhydroxyurethanes with tunable structure-property relationships
Sammanfattning : Redesigning polymeric materials and rethinking their use is imperative in the prospect of a more sustainable future. Critical aspects in this endeavor are the use of renewable monomers to decrease the environmental footprint, implementing green syntheses and production processes and the design for increased recyclability as an end-of-life option to diverge from the generation of plastic waste.

17. Interactions between polymeric dispersants and colloidal ceramic surfaces
Sammanfattning : Increased use of environmentally acceptable chemicals and reduced energy consumption are two foreseeable demands within the ceramics industry. This will require the replacement of organic solvents and lowering of sintering temperatures. LÄS MER
18. From Responsive Interfaces to Honeycomb Membranes by Controlled Radical Polymerisation
Sammanfattning : In this study, surface modification of both organic and inorganic substrates (in terms of cellulose and silica nanoparticles, respectively) has been explored using surface-initiated atom transfer radical polymerisation (ATRP). The desire to modify bio-based materials to fit into new application areas and the need for bio-based materials with improved material properties is steadily increasing due to environmental concern.

19. Tuning Properties of Surfaces and Nanoscopic Objects using Dendronization and Controlled Polymerizations
Sammanfattning : In this study, dendronization and grafting via controlled polymerization techniques, atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP), have been explored. Modification of surfaces and cellulose using these techniques, which enable grafting of well-defined polymer architectures, has been investigated. LÄS MER
20. Birch xylan modification by lactide grafting
Sammanfattning : The wood based biorefinery concept has led to an increasing interest in the possibility of using hemicelluloses as a source for value added products. Hemicelluloses are dissolved in large amounts in the process liquor during kraft pulping. LÄS MER
