2. 1. Formation and properties of polyelectrolyte multilayers on wood fibres : influence on paper strength and fibre wettability

   Author : Rikard Lingström; Lars Wågberg; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; polyelectrolyte; multilayer; adsorption; reflectance; contact angle; dynamics; paper; mechanical properties; individual; wood fibre; Chemistry; Kemi;

   Abstract : The work in this licentiate thesis examines the adsorption of polyelectrolyte multilayers (PEM) onto wood fibres as a new way to influence the properties of the fibre surfaces and hence the fibres. Fundamental aspects of PEM formation on wood fibres have been studied, and discussed in terms of paper strength and wood fibre wettability. READ MORE

4. 2. On the Adhesion Between Substrates Covered with Polyelectrolyte Multilayers

   Author : Rikard Lingström; Lars Wågberg; Lennart Piculell; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fibre; polyelectorlyte; multilayer; wettability; contact angle; paper strength; atomic force microscopy; surface force apparatus; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : This thesis examines the formation of Polyelectrolyte Multilayers (PEM) on cellulose fibres as a new way of influencing the fibre surface and the adhesion between wood fibres. The aim of the study was to enhance the fundamental understanding of the adsorption mechanisms behind the formation of Polyelectrolyte Multilayers on cellulose fibres; to study how the properties of the layers can be influenced and to show how the properties of the layers influence the adhesion between the fibres and the strength of paper sheets made from the PEM treated fibres.
