  1. 1. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Petra M Hansson; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Abstract : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

  3. 3. Surface Force and Friction effects of adsorbed layers and surface topography

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Xiaoyan Liu; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction; nanotribology; surface forces; diblock copolymer; lipid; QCM-D; AFM; optical reflectometry; neutron reflectivity; X-ray reflectivity; micro-patterned surface; Kemi; Chemistry;

    Abstract : Interfacial features of polymers are a complex, fascinating topic, and industrially very important. There is clearly a need to understand interactions between polymer layers as they can be used for controlling surface properties, colloidal stability and lubrication. The aim of my Ph. READ MORE

  4. 4. Surface Forces in Complex Liquid Systems

    University dissertation from Physical Chemistry 1, Lund University

    Author : Plamen Petrov; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adsorption of polyelectrolytes and surfactants; hydrophobically modifiedpolyelectrolytes; polymer-surfactant interactions; chargereversal; polyamines; electrical double layer; silica; mica; surface forces; ellipsometry; L3 andlamellar phases; bicontinuous; Physical chemistry; Fysikalisk kemi;

    Abstract : Surface force measurements, combined with ellipsometry, were performed on several colloidal liquid systems. We studied the forces between mica surfaces in presence of dilute aqueous solutions of ethylenediamine (divalent) and spermidine (trivalent) hydrochlorides. READ MORE

  5. 5. Polymer Mediated Surface Forces

    University dissertation from Physical Chemistry 1, Lund University

    Author : Martin Turesson; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte Solutions; Charge Inversion; Monte Carlo Simulations; Depletion Stabilization; Correlation Attraction; Colloid stability;

    Abstract : The issue of controlling the stability between colloidal particles in solution is important, at least for industrial applications, relying on efficient flocculation or stable dispersions. The objective of this thesis is to shed some light on fundamental mechanisms behind the interplay between attractive and repulsive forces, in solutions containing colloids and polymers. READ MORE
