    Sammanfattning : Polymer dispersions are employed in a wide variety of applications as film formers. Especially in the coating-, paint-, pharmaceutical and hygiene industry polymer dispersions are to a large extent used as barriers, controlled-release agents and adhesives. LÄS MER

  7. 5. NMR Diffusometry and Dynamic NMR Microscopy Studies of Colloidal Systems

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

    Sammanfattning : 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. LÄS MER
