1. Ageing behavior of plastics used in automotive fuel systems
Sammanfattning : The increase in service temperature and the use of biobased fuels, such as biodiesel, have raised concerns on the short/long-term performance of plastic components used in automotive fuel systems.In this work the ageing behavior of unreinforced and glass-fibre reinforced polyamide 12 (PA12), exposed to three different fuels (petroleum diesel, biodiesel, and a mixture of these (80/20)) at high temperature, was investigated.

2. 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.

3. Preparation and Compatibilizing Properties of Poly(styrene-graft-ethylene oxide) in Polymer Blends
Sammanfattning : One of the main trends in the polymer industry today is the increasing importance of polymer blends. Combining two or more immiscible polymers in a polymer blend often leads to multi-phase materials with desirable properties. LÄS MER
4. Morphology of Polymers - Development of Electron Microscopy Methods
Sammanfattning : Most polymeric materials used today are not simple homopolymers, but consist of more than one polymer, which lead to morphologies of different length scale and shape. It is important to receive knowledge of the morphologies because the properties of the materials change depending on the structure. LÄS MER
5. Designed from Recycled: Microwave-Assisted Upcycling of Plastic Waste
Sammanfattning : Mismanagement of plastic waste is of great concern. To reach a more sustainable society, methodologies to handle materials in a more circular way needs to be developed. LÄS MER
