1. Structure-Property Relationships of Surfactants at Interfaces and Polyelectrolyte-Surfactant Aggregates
Sammanfattning : The first part of this thesis is concerned with thestructure-property relationships in nonionic surfactantsystems. The main aim was to investigate how the surfactantstructure influences the adsorption at interfaces andinteractions between surfactant coated interfaces. LÄS MER
2. Effects of a Novel Amphiphilic Graft Copolymer on Ternary Mixtures of Surfactant, Water, and Oil
Sammanfattning : An amphiphilic graft copolymer, with hydrophilic poly(ethylene glycol) monomethyl ether side chains grafted onto a hydrophobic poly(dodecyl methacrylate) backbone, has been synthesized. The side chains are water soluble and the backbone is soluble in oils such as cyclohexane and isooctane. LÄS MER
3. Association Phenomena in Aqueous Solutions of Surfactants and Hydrophobically Modified Polymers
Sammanfattning : Interactions between ionic surfactants (sodium dodecyl sulfate and dodecyltrimethylammonium chloride) and nonionic polymers ((hydroxyethyl)cellulose, ethyl(hydroxyethyl)cellulose and their hydrophobically modified analogous) have been studied by means of rheology, pulsed field gradient nuclear magnetic resonance (PFG NMR), time-resolved fluorescence quenching (TRFQ), dynamic light scattering (DLS) and cryo-transmission electron microscopy (cryo-TEM). In all experiments surfactants have been added in various amounts to polymer solutions at fixed concentrations. LÄS MER
4. Green Colloid Chemistry: Characterization of Environmentally Friendly Nonionic Surfactant Systems
Sammanfattning : Phase diagrams of mixed alkylglucoside surfactants, n-nonyl-b-D-glucopyranoside and n-decyl-b-D-glucopyranoside (C9G1 and C10G1) have been examined for the purpose of determining the microstructure surrounding a closed-loop miscibiliyt gap. There are large deuterium isotope effects on the phase diagram. LÄS MER
