  1. 1. From Responsive Interfaces to Honeycomb Membranes by Controlled Radical Polymerisation

    Författare :Daniel Nyström; Anders Hult; Søren Hvilsted; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Isoporous membranes; Silica nanoparticles; ATRP; Functional surfaces; cellulose; Polymer chemistry; Polymerkemi;

    Sammanfattning : In this study, surface modification of both organic and inorganic substrates (in terms of cellulose and silica nanoparticles, respectively) has been explored using surface-initiated atom transfer radical polymerisation (ATRP). The desire to modify bio-based materials to fit into new application areas and the need for bio-based materials with improved material properties is steadily increasing due to environmental concern.

    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

  4. 3. Advanced Functional Thin Films and Networks towards Biological Applications

    Författare :Surinthra Mongkhontreerat; Michael Malkoch; Anders Hult; David Haddleton; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Sammanfattning : Functional polymeric scaffolds have been employed in biological applications as several utilities, from nano-sized drug delivery systems to concrete implants. The progression in biological fields essentially relies on finding an appropriate material to fulfil the critical requirements for various types of applications with great potential for tuning functionality and mechanical properties.

  5. 4. 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
