1. Long-term properties of polyethylene films : efficiency of a natural antioxidant
Sammanfattning : There is a growing awareness of the risks of pollution in biological systems and one potential problem is the synthetic antioxidants, used for e.g. the stabilisation of polymeric materials. Natural antioxidants are an interesting alternative, if the high efficiency and thermal stability of the synthetic compounds can be reached. LÄS MER
2. Bioactive nanocellulose materials for the treatment of chronic wounds
Sammanfattning : Chronic wounds represent a burden for the healthcare system and significantly affect the quality of life of the patients. There is currently a lack of efficient treatments but new, improved therapeutic approaches are under development. LÄS MER
3. 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
4. Design, Synthesis and Evaluation of Catalytic Chalcogenide Antioxidants
Sammanfattning : This thesis describes the design, synthesis and evaluation of novel chalcogenide antioxidants.A computational model for the prediction of antioxidant properties of chalcogen-containing antioxidants has been developed. LÄS MER
5. Antioxidant-Impregnated Polymers / Antioxidant Ability and Interactions with Food
Sammanfattning : Interactions between antioxidant-impregnated low-density polyethylene (LDPE) and polypropylene (PP), and oxygen-sensitive foods have been investigated. BHT and a-tocopherol are two antioxidants commonly used in both foods and polymers. In general, BHT was rapidly lost from LDPE film in contact with various foodstuffs. LÄS MER
