  2. 16. NMR Diffusometry and Dynamic NMR Microscopy Studies of Colloidal Systems

    Author : Helena Wassenius; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; diffusion behaviour; dynamic NMR microscopy; NMR diffusometry; core-shell latex particles; NMR velocimetry; rheology; colloidal systems;

    Abstract : In this thesis, the NMR diffusometry and dynamic NMR microscopy methods were shown to be useful techniques with a great potential for the study of colloidal systems. In Paper I-II, NMR diffusometry was used to study the behaviour of surfactant and polymer molecules that are normally important components in colloidal dispersions and emulsions. READ MORE

  4. 17. On the processing and properties of cellulose-containing polymeric materials

    Author : Ruth Arino Marine; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological properties; compounding; dispersion; ionic liquids; ethylene-acrylic acid copolymer; cellulose fibres; gels;

    Abstract : ABSTRACTCellulose fibres have properties that make them very attractive as a reinforcement for thermoplastic polymers. Renewability, biodegradability, very good availability and low cost are some general advantages. READ MORE

  5. 18. On the Characterization and Generation of Flow Marks on Polymeric Surfaces

    Author : Giovanna Iannuzzi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tiger stripes; surface defects; rheological properties; injection moulding; polymer processing; flow marks;

    Abstract : Polymer-based materials are widely used in the automotive industry for producing vehicle parts, for instance car bumpers, dash boards etc. A common manufacturing process for such components is injection moulding. READ MORE

  6. 19. Flow, expansion and processing behaviours of gas-containing filled polyethylene

    Author : Nabil Khoshaba; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical properties; flow rate; critical pressure; injection moulding; expansion kinetics; fillers; rheological properties; foaming; composite materials; partial pressure; capillary viscometry; Blowing agent;

    Abstract : The utilization of fillers in polymeric materials has exhibited a substantial growth during the last decades. Chalk (calcium carbonate) and glass fibres are two common examples of such fillers. These fillers/reinforcing elements are used in order to reduce the cost of material and change its physical (mechanical) properties. READ MORE

  7. 20. On the processing and properties of cellulose-containing polymeric materials

    Author : Ruth Arino Marine; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion; extrusion; injection moulding; ionic liquids; compounding; ethylene-acrylic acid copolymer; gels; cellulose fibres; rheological properties;

    Abstract : Cellulose fibres have properties such as renewability, biodegradability, very good availability and low cost that make them very attractive as a reinforcement for thermoplastic polymers. Other more specific favourable properties are low density, high specific stiffness, low abrasive nature and their potential for modification. READ MORE
