1. Heterogeneous Film-Forming Latexes : Preparation - Morphology - Mechanical Properties
Sammanfattning : This thesis describes the preparation of heterogeneous latexes, which may serve as binders in coating applications, and the characterization of these. The latexes were prepared in two-stage seeded emulsion polymerization. LÄS MER
2. Crystallinity and Morphology of Starch Polymers in Films
Sammanfattning : Starch is a renewable material that can be converted into biodegradable plastic products, or films with excellent oxygen barrier properties. Films of potato starch, amylose, amylopectin and blends thereof were made by solution casting. LÄS MER
3. Polypropylene : Morphology, defects and electrical breakdown
Sammanfattning : Crystal structure, morphology and crystallization kinetics of melt-crystallized polypropylene and poly(propylene-stat-ethylene) fractions with 2.7 to 11.0 mol% of ethylene were studied by differential scanning calorimeter, wide- and small-angle X-ray scattering, polarized light microscopy, transmission electron microscopy and infrared spectroscopy. LÄS MER
4. Electronic Structure and Film Morphology Studies of PTCDI on Metal/Semiconductor Surfaces
Sammanfattning : Organic semiconductors have received increasing attention over the last decades as potential alternatives for inorganic semiconductors. The properties of these films are highly dependent on their structural order. LÄS MER
5. Film morphology for organic solar cells : Effect of Solubility and Gravity Conditions
Sammanfattning : Organic photovoltaics is a promising environmentally friendly technology, due to their printability, light-weight nature and mechanical flexibility, and the possibility to use off-grid. Research and development in this field has resulted in power conversion efficiencies of over 15%. LÄS MER
