    Författare :Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; atom transfer radical polymerisation; ring-opening metathesis polymerization; reversible addition-fragmentation chain transfer polymerization; 2; 2-bis methylol propionic acid; tri-block copolymers; rheology; differential scanning calorimerty; 1H-NMR self-diffusion; Polymer chemistry; Polymerkemi;

    Sammanfattning : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. LÄS MER

  2. 2. Polyester dendrimers for biomedical applications

    Författare :Patrik Stenström; Michael Malkoch; Javier de la Mata; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Dendrimers are perfectly defined and highly branched large molecules with a high density of functional groups that makes them interesting for a variety of biomedical applications such as drug delivery, theranostics and as antimicrobials. Their synthesis can be complicated, time-consuming and expensive which has been an obstacle to their success. LÄS MER

  3. 3. Designing Polymers for Biological Interfaces - From Antifouling to Drug Delivery

    Författare :Pontus Lundberg; Michael Malkoch; Anders Hult; Scott M. Grayson; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Sammanfattning : Unspecific interactions, at the interface between a synthetic material and an aqueous biological environment, leading to irreversible protein adsorption can cause to undesired consequences. These include fouling of a boat hull or a triggered immune response. LÄS MER

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

    Författare :Emma Östmark; Eva Malmström; Heikki Tenhu; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Dendrimers : Synthesis, Characterization and Use in Thiol-Ene Networks

    Författare :Camilla Nilsson; Eva Malmström; Andreas Heise; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; polymer; molecular physics; Polymer chemistry; Polymerkemi;

    Sammanfattning :  Dendrimers are perfectly branched, well-defined macromolecules with a layered structure and a large amount of peripheral end groups. The high functionality in combination with the possibility of dendrimers to adopt a globular shape at high molecular weights, gives them very unique properties. LÄS MER
