  1. 1. Polyelectrolyte complexes their preparation, adsorption behaviour and effect on paper properties

    University dissertation from Stockholm : KTH

    Author : Caroline Ankerfors; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : 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. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : 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. READ MORE

  3. 3. The effects of cellulosic fiber charges on polyelectrolyte adsorption and fiber-fiber interactions

    University dissertation from Stockholm : KTH

    Author : A. Elisabet Horvath; KTH.; [2006]

    Abstract : 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. READ MORE

  4. 4. Polyelectrolyte adsorption on oppositely charged surfaces - Conformation and adsorption kinetics

    University dissertation from Stockholm : KTH

    Author : Lars-Erik Enarsson; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte adsorption; adsorption kinetics; adsorption isotherms; conformation; bridging; stagnation point adsorption reflectometry; quartz crystal microgravimetry; polyelectrolyte titration; cationic polyacrylamide; cationic dextran; colloidal silica; silica surfaces; pulp; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : 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.
