  1. 1. Properties and Applications of Temperature Sensitive Gels

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Matz Andersson; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Swelling kinetics; Poly N-isopropylacrylamide gel; NiPAAm; Immobilisation; Hydrogels; Gel extraction; Flory-Huggins; Diffusion; Controlled Release; Kemiteknik och kemisk teknologi;

    Abstract : The work presented deals with the characterisation and application of critical gels. In order to provide a theoretical foundation, the thermodynamics of the reversible swelling and shrinking behaviour of such gels is outlined. The temperature-sensitive poly(N-isopropylacrylamide) gel (NiPAAm) was chosen for experimental investigation. READ MORE

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Imberg; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Biodegradable; CLSM; Composite Particles; Controlled Release; Cubic Phases; Drug Delivery; Flory-Huggins Theory; FT-PGSE-NMR; IPMS; Liquid Phase; Lipid Domains; Liquid Handler; Microspheres; Microstructure; Phase Behaviour; Phase Separation; Polymer Matrix; SAXS; Segregation; Sponge Phase; Swelling; Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; fysikalisk och oorganisk farmaceutisk kemi; Physical and Inorganic Pharmaceutical Chemistry;

    Abstract : A new kind of lipid/polymer composite particle, consisting of a biodegradable polymer matrix with well-defined lipid domains, has been created. The lipid used is the water-swelling lipid monoolein (MO), which forms a reversed bicontinuous cubic diamond structure in aqueous solutions. READ MORE

  3. 3. Storage Stability and Phase Separation Behaviour of Polymer-Modified Bitumen Characterization and Modelling

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Jiqing Zhu; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer-modified bitumen; Storage stability; Phase separation; Fluorescence microscopy; Phase-field modelling; Polymermodifierad bitumen; Lagringsstabilitet; Fasseparation; Fluorescensmikroskopi; Fas-fälts modellering; Transportvetenskap; Transport Science;

    Abstract : Polymer-modified bitumen (PMB) is a high-performance material for road construction and maintenance. But its storage stability and phase separation behaviour are still not sufficiently understood and need to be studied toward a more successful and sustainable application of PMB. READ MORE

  4. 4. Particle-Induced Phase Separation in Aqueous Solutions containing Colloidal Particles and Adsorbing Polymers

    University dissertation from Physical Chemistry, Lund University

    Author : Martin Olsson; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; theoretical calculations; particle-induced phase separation; phase behaviour; surfactant; colloidal particles; adsorbing polymer;

    Abstract : The influence of added colloidal particles on the phase behaviour of a polymer solution was investigated. Binary, quasi-binary and mixed polymer solutions were used in the study, where at least one of the polymers had an affinity for the surfaces of the colloidal particles. READ MORE

  5. 5. Solution properties of a hydrophobically modified polymer

    University dissertation from Physical Chemistry 1, Lund University

    Author : Krister Thuresson; Lund University.; Lunds universitet.; [1996]
    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
