  1. 1. Functional Dendritic Materials using Click Chemistry : Synthesis, Characterizations and Applications

    Författare :Per Antoni; Anders Hult; Michael Malkoch; Stefan Hecht; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; Dendron; Dendritic; Hyperbranched; Click; Chemistry; CuAAc; One-Pot; Multi-functional; Simultaneous; Honeycomb; Isoporous; MALDI; NMR; GPC; TGA; DSC; Polymer chemistry; Polymerkemi;

    Sammanfattning : Förfrågan efter nya och mer avancerade applikationer är en pågående process vilket leder till en konstant utveckling av nya material. För att förstå relationen mellan en applikations egenskaper och dess sammansättning krävs full förståelse och kontroll över materialets uppbyggnad. LÄS MER

  3. 2. Dendron decorated chromophores for optical power limiting applications

    Författare :Robert Vestberg; KTH; []
    Nyckelord :Life sciences and physical sciences; polymer chemistry; optics physics; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The need for protection of eyes and electro-optic sensors from powerful lasers has increased the need for new and better optical power limiting (OPL) materials that can protect against laser light. In this study the synthesis and characterization of dendron-coated OPL chromophores (porphyrins, thiophenes, and platinum(II) acetylides) are discussed. LÄS MER

  4. 3. 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

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

    Författare :Pontus Lundberg; Michael Malkoch; Anders Hult; Scott M. Grayson; KTH; []
    Nyckelord :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

  7. 5. Synthesis and characterization of dendritic architectures

    Författare :Andreas Nyström; Anders Hult; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Chemistry; Kemi;

    Sammanfattning : The goal of this work was to synthesize different dendritic architectures and evaluate the effect from the dendrons on the material properties. The work presented in this licentiate thesis, Synthesis and Characterization of Dendritic Architectures, is divided into major parts. LÄS MER
