  2. 1. Graft polymerization

    Author : Torbjörn Lindberg; KTH; []
    Keywords : ;

    Abstract : This thesis is focused on morphological aspects of polymericsubstrates used in graft polymerization. Morphological changesof selected polymer systems were investigated in the virginstate and after irradiation, during the progress of graftpolymerization, in the final grafted state and duringsubsequent degradation.

  4. 2. Fiber-Supported Hydrogels with Controlled surface Properties

    Author : Jan Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellulose; fiber; ozone; polypropylene; graft polymerization; hydrogel; surface;

    Abstract : Hydrogels are emerging materials that have the ability to hold a substantial amount of water. However, the low mechanical performance of hydrogels is often a limitation for extending the field of applications. READ MORE

  5. 3. Zwitterionic Separation Materials for Liquid Chromatography and Capillary Electrophoresis : Synthesis, Characterization and Application for Inorganic Ion and Biomolecule Separations

    Author : Wen Jiang; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; Zwitterionic; stationary phase; separation; liquid chromatography; capillary electrophoresis; sulfobetaine; modification; covalently bonded; graft polymerization; ζ-potential; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : Liquid Chromatography (LC) and Capillary Electrophoresis (CE) are modern analytical techniques that play very important roles in many areas of modern science such as life science, biotechnology, biomedicine, environmental studies, and development of pharmaceutics. Even though these two techniques have existed and been subjected to studies for several decades, the developments of new separation materials for them are still very important till now in order to meet the different new demands for improvement from other disciplines in science.
