21. Evolution and control of the three dimensional functional microstructure of Polymer:Fullerene photovoltaic blends
Sammanfattning : Polymer:fullerene bulk-heterojunction thin films show great promise for use as active layers in organic solar cells. However, their low thermal stability is a hindrance that complicates the manufacturing and influences the lifetime of devices. LÄS MER
22. Functional Copolymers of Polyvinylpyrrolidone
Sammanfattning : In many ways, polyvinylpyrrolidone (PVP) has a unique combination of chemical and physical properties. Unlike most polymers it is soluble in water as well as a number of organic solvents. PVP also has excellent film forming properties, outstanding chemical stability, complexing ability, low toxicity, and good adherence to many different substrates. LÄS MER
23. Polymer Nanocomposites in Thin Film Applications
Sammanfattning : The introduction of a nanoscopic reinforcing phase to a polymer matrix offers great possibilities of obtaining improved properties, enabling applications outside the boundaries of traditional composites. The majority of the work in this thesis has been devoted to polymer/clay nanocomposites in coating applications, using the hydroxyl-functional hyperbranched polyester Boltorn® as matrix and montmorillonite clay as nanofiller.

24. Salting-out of Colloidal Latex Particles Grafted with Poly(ethylene glycol)
Sammanfattning : Colloidal particles dispersed in a medium are important both in nature and in industry. The stability of colloidal particles is determined by the interactions between them and can be improved by steric stabilization. There is no conclusive understanding of how these sterically stabilized particles become unstable. LÄS MER
25. The assessment of disease progression in keratoconus and corneal crosslinking in thin corneae
Sammanfattning : Keratoconus generally manifests in adolescents, and can progress leading to severely impaired vision. The risk of progression is inversely correlated to age; thus younger patients are at higher risk than older ones. Progressive keratoconus can be halted by corneal crosslinking (CXL). LÄS MER
