1. Polyelectrolyte complexes : their preparation, adsorption behaviour and effect on paper properties
Sammanfattning : In this work, the formation of polyelectrolyte complexes (PECs) has been studied using a jet mixing method not previously used for mixing polyelectrolytes. The PECs were formed from two weak polyelectrolytes, i.e. LÄS MER
2. Polyelectrolyte complexes : Preparation, characterization, and use for control of wet and dry adhesion between surfaces
Sammanfattning : This thesis examines polyelectrolyte complex (PEC) preparation, adsorption behaviour, and potential use for control of wet and dry adhesion between surfaces. PEC formation was studied using a jet-mixing method not previously used for mixing polyelectrolytes. LÄS MER
3. The effects of cellulosic fiber charges on polyelectrolyte adsorption and fiber-fiber interactions
Sammanfattning : The surface charges of cellulosic fibers contribute to several papermaking operations that influence the manufacture and final properties of paper. This thesis investigates the effect of the surface charges on wet-end chemistry, e.g. LÄS MER
4. Polyelectrolyte adsorption on oppositely charged surfaces - Conformation and adsorption kinetics
Sammanfattning : Denna avhandling presenterar experimentella studier av polyelektrolytadsorption på motsatt laddade ytor, där substrat av både kiseloxid och blekt barrsulfatmassa har använts. Ett huvudsakligt syfte med denna forskning var att karaktärisera konformationen hos adsorberade skikt av katjonisk polyakrylamid (CPAM) i jämförelse med katjonisk dextran (Cdextran) och relatera denna information till inbindningskapaciteten av kolloidal kiselsyra. LÄS MER
5. Appropriate conditions for polyelectrolyte titration to determine the charge of cellulosic fibers
Sammanfattning : The polyelectrolyte titration method has been developed overthe years in order to determine the surface charge ofcellulosic fibers. The conditions have been varied depending onthe author. LÄS MER
