11. Polymer Ionic Materials: A Study of new Materials for Solid Polymer Fuel Cells and Rechargeable Polymer Batteries
Sammanfattning : Ion-containing polymeric materials are interesting for use in a wide variety of applications, where the flexible, yet mechanically stable, polymer matrix is essential. Intensive research is presently going on worldwide for applications as electrolytes in solid polymer batteries and fuel cells, where the ion-conducting polymer also serves as an electrode separator.

13. Improving properties of poly(lactic acid) biopolymer for use in food packaging
Sammanfattning : The petroleum-based plastics are widely used for food packaging applications because of their low cost, easy processability, and tunable properties to meet the specific needs of food packaging. However, these polymers are non-biodegradable, leading to a substantial amount of plastic waste in both land and marine ecosystems. LÄS MER
14. Ternary Block Copolymer - Water - "Oil" Systems: Effects of "Oil" Type and Block Size on Phase Behaviour and Structure
Sammanfattning : It has recently been established in our group that amphiphilic block copolymers consisting of a hydrophilic and a hydrophobic part can self-assemble in the presence of selective solvents (“water” and “oil”) into a variety of different solution and lyotropic liquid crystalline microstructures. The effects of the “oil” type, hydrophilic block size and hydrophobic block type on the phase behavior and microstructure of ternary isothermal copolymer - oil - water systems have been addressed in this thesis.

15. Aluminium oxide - poly(ethylene-co-butylacrylate) nanocomposites : synthesis, structure, transport properties and long-term performance
Sammanfattning : Polymer nanocomposites are promising materials for dielectrical use in high voltage applications and insulations. This work presents a study of nanocomposites based on poly(ethylene-co-butyl acrylate) with two different comonomer compositions and two different aluminium oxide nanoparticles. LÄS MER
