1. 1. Poly(Ethylene Oxide) Based Bottle-Brush Polymers and their Interaction with the Anionic Surfactant Sodium Dodecyl Sulphate : Solution and Interfacial Properties

   Författare :Joseph Iruthayaraj; Per M. Claesson; Regine v. Klitzing; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PEO brush polymers; brush polymers; PEO; poly ethylene oxide ; polymer-surfactant; sodium dodecyl sulphate SDS ; Ellipsomtery; PEO-SDS interactions; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : The aim of this thesis work is to study the physico-chemical properties of poly(ethylene oxide), PEO, based brush polymers both in solution and at solid/aqueous interfaces. The importance of studying the surface properties of brush polymers can be related to a broad spectrum of interfacial-related applications such as colloidal stability, lubrication, detergency, protein repellency to name a few.

3. 2. Adsorption behaviour of bottle-brush and block copolymers at solid-liquid interfaces

   Författare :Geoffrey Olanya; Per M. Claesson; Orlando Rojas; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adsorption; Lubrication; Layer viscoelasticity; Protein repellency; Polymer architecture; Silica; Bottle-brush polymers; Poly ethylene oxide ; PEO; Block copolymer; Poly N-isopropylacrylamide ; QCM-D; AFM; Reflectometry; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : This thesis was spurred on by needs of current scientific and technological developments in the area of surface modification by use of adsorbed polymer layers. The importance of surface properties of polymer layers can be imparted in a broad spectrum of interfacial-related applications like lubrication, colloidal stability, detergency, and protein resistant surfaces, to just mention a few.
