  2. 1. Solution properties of a hydrophobically modified polymer

    Author : Krister Thuresson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sodium dodecylsulfate; surfactants; fluorescence; light scattering; NMR; rheology; cloud point; phase behaviour; polyelectrolytes; ethyl hydroxyethyl cellulose; hydrophobically modified; water soluble polymers; aggregation number; association; Physical chemistry; Fysikalisk kemi;

    Abstract : The influence of hydrophobic modification on solution properties of water-soluble polymers in the semi-dilute regime have been studied. The nonionic ethyl(hydroxyethyl)cellulose (EHEC) and its hydrophobically modified analogue (HM-EHEC) are used as model substances. READ MORE

  4. 2. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution

    Author : Geng Wang; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calorimetry; differntial scanning; isothermal titration; enthalpy; electrolyte; micelles; self-association; thermal gelling; interaction; alkyltrimethylammonium halides; sodium dodecylsulfate; surfactants; polymers; ethyl hydroxylethyl cellulose; viscosity; phase behavior; self-diffusion NMR; Physics; Fysik; Chemistry; Kemi; Fysicumarkivet A:1997:Wang;

    Abstract : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. READ MORE

  5. 3. Properties of stabilizers in colloidal dispersions

    Author : Catherine Boissier; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surfactants; conformation; polymers; NMR relaxometry; exchange dynamics; residence times; adsorption; polymer-surfactant interaction; NMR diffusometry;

    Abstract : Surfactants and polymers are frequently used as stabilizers in colloidal dispersions. Depending on their solubility and the interactions in their local environment, their tendency to remain adsorbed on a surface will differ. READ MORE

  6. 4. Assemblies of Colloidal Hydrochar Nanoparticles and their Derived Activated Carbons for CO2 Sorption

    Author : Xia Wang; Niklas Hedin; Gunnar Svensson; Oren Regev; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; colloids; hydrothermal carbonization; glucose; directed assembly; reactive infiltration; templating; silicon carbide; tricopper silicide; redispersion; nanoparticles; chemical activation; activated carbons; CO2 sorption; Materials Chemistry; materialkemi;

    Abstract : Carbon-rich colloids are of great fundamental and technological interest and in this thesis, I tested a range of hypotheses and studied aspects of small hydrochar-based colloids and their colloidal and material chemistry. Crude hydrochar dispersions were synthesized by hydrothermal carbonization of glucose and purified by dialysis. READ MORE

  7. 5. Interactions Between Biopolymers and Surfactants with Focus on Fluorosurfactants and Proteins

    Author : Lubica Macáková; Per Claesson; Fredrik Höök; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Abstract : The aim of this thesis was to obtain a better understanding of the association between surfactants and biopolymers in bulk solutions and at solid/aqueous liquid interface. In order to do this, the interactions between surfactants and biopolymers were investigated with a variety of experimental techniques. READ MORE
