  3. 2. Tuning Properties of Surfaces and Nanoscopic Objects using Dendronization and Controlled Polymerizations

    Författare :Emma Östmark; Eva Malmström; Heikki Tenhu; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; cellulose; Atom Transfer Radical Polymerization; Ring-Opening Polymerization; surface modification; grafting; superhydrophobic; amphiphilic polymer; block copolymer; Atomic Force Microscopy; Polymer chemistry; Polymerkemi;

    Sammanfattning : In this study, dendronization and grafting via controlled polymerization techniques, atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP), have been explored. Modification of surfaces and cellulose using these techniques, which enable grafting of well-defined polymer architectures, has been investigated. LÄS MER

  7. 5. Complex Macromolecular Architectures by Atom Transfer Radical Polymerization

    Författare :Anna Carlmark; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer chemistry; controlled radical polymerization;

    Sammanfattning : Controlled radical polymerization has proven to be a viableroute to obtain polymers with narrow polydispersities (PDI's)and controlled molecular weights under simple reactionconditions. It also offers control over the chain-]ends of thesynthesized polymer. LÄS MER
