6. Exploring crosslinked networks of polymers and hybrid cellulose materials
Sammanfattning : The field of polymer chemistry has in recent decades had an immense development, resulting in new functional materials with groundbreaking applications. This has been driven partly by strong interdisciplinary alliances between the fields of medicine, biology, chemistry, and materials science. LÄS MER
7. Surface modification of cellulose-based fibres for use in advanced materials
Sammanfattning : The awareness of our need for a sustainable society has encouraged the search for renewable, high quality materials that can replace oil-based products. This, in combination with increased competition in the forest industry, has stimulated a lot of research into different types of wood-based materials where cellulose-rich fibres are combined with different types of polymers.

9. Mixed Block Copolymer Solutions: Self-Assembly and Interactions
Sammanfattning : This thesis incorporates studies on the aqueous systems of two types of thermoresponsive amphiphilic block copolymers; a series of nonionic triblock copolymers comprising blocks of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) denoted as PEO-PPO-PEO block copolymers, and a series of ionic diblock copolymers consisting of one charged block and one block of poly(N-isopropylacrylamide) (PNIPAAM). Various techniques, such as dynamic and static light scattering (DLS and SLS), small angle X-ray and neutron scattering (SAXS and SANS), high sensitivity differential scanning calorimetry (HSDSC), turbidimetry, electrophoretic mobility measurements, and two-dimensional proton NMR nuclear Overhauser effect spectroscopy (2D 1H NMR NOESY), were applied to study these block copolymer systems.

10. Towards Functional Nanopores Using Polymers
Sammanfattning : In nature there are several examples of nanometer sized gateways able to control the passage of molecules and other substances with remarkable precision. This has inspired research in trying to create nanoscale openings which resemble such gateways. LÄS MER
