  1. 11. 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 : Polysaccharides are an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Due to their natural diversity they can be found in many special applications, e.g. in the biomedical sector and are the major renewable resource for materials of many kinds. LÄS MER

  5. 14. Functional Degradable Polymers by a Radical Chemistry approach

    Författare :Jenny Undin; Ann-Christine Albertsson; Anna Finne-Wistrand; Jukka Seppälä; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : One class of polymers that is inherently of great value for many applications is the aliphatic polyesters. Such polymers are very suitable for use as temporary guides, scaffolds, for tissue formation and other biomedical applications, due to their biocompatibility, degradability and appropriate mechanical properties.
