1. Latex Colloid Dynamics in Complex Dispersions : Fluorescence Microscopy Applied to Coating Color Model Systems
Sammanfattning : Coating colors are applied to the base paper in order to maximize the performance of the end product. Coating colors are complex colloidal systems, mainly consisting of water, binders, and pigments. To understand the behavior of colloidal suspensions, an understanding of the interactions between its components is essential.. LÄS MER
2. Flocculation with Polyelectrolytes in Latex and Microbial Systems
Sammanfattning : Adsorption of cationic polyelectrolytes onto polystyrene latices was studied as function of polymer chemical composition and molecular weight, polymer and surface charge density and ionic strength. The ratio between polymer charges and surface charges was close to one when distances between polymer and surface charges were equal. LÄS MER
3. Bimodal Hard/Soft Latex Blends
Sammanfattning : Polymer dispersions are employed in a wide variety of applications as film formers. Especially in the coating-, paint-, pharmaceutical and hygiene industry polymer dispersions are to a large extent used as barriers, controlled-release agents and adhesives. LÄS MER
4. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging
Sammanfattning : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. LÄS MER
5. Tailored adhesion of PISA-latexes for cellulose modification and new materials
Sammanfattning : This thesis is focused on applying modification chemistry to already known cellulosic substrates from wood (i.e. cellulose nanofibrils, CNFs, and cellulose nanocrystals, CNCs). LÄS MER
