1. 16. Structures of Polyelectrolyte Multilayers and Preasorbed Mucin : The Influence of Counterions

   Författare :Zsombor Feldötö; Eva Blomberg; Regine von Klitzing; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : The focus in this thesis has been to gain a fundamental understanding of how different type of salts affect preadsorbed polyelectrolytes, both natural and synthetic. The knowledge from the fundamental work is then applied on a commercial system to investigate if the efficiency can be enhanced. LÄS MER

3. 17. 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.

4. 18. Self Assembly at the Liquid Air Interface

   Författare :Niga Petru; Rutland Mark; Ye Shen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VSFS; SFG; interface; crown ethers; ethylene oxides; ionic liquids; fatty acids; domains.; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : The aim of this work is to study the interfacial properties of amphiphilic compounds at the liquid–air interface in an attempt to develop a comprehensive understanding of their orientation as well as the influence of their interaction with the solvent on the interfacial layer properties. Using Vibrational Sum Frequency Spectroscopy (VSFS) as the main tool, the molecular structure of the amphiphilic layer and the amphiphile–solvent relation can be illuminated in great detail – it is arguably the most sensitive surface spectroscopy currently available.

7. 20. Designing Polymers for Biological Interfaces - From Antifouling to Drug Delivery

   Författare :Pontus Lundberg; Michael Malkoch; Anders Hult; Scott M. Grayson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : Unspecific interactions, at the interface between a synthetic material and an aqueous biological environment, leading to irreversible protein adsorption can cause to undesired consequences. These include fouling of a boat hull or a triggered immune response. LÄS MER
