    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

  4. 3. Surface Modification of Nanocellulose towards Composite Applications

    Författare :Assya Boujemaoui; Anna Carlmark Malkoch; Eva Malmström Jonsson; Julien Bras; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; surface modification; functionalization; composites; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Nanocelluloses have attracted great interest during recent decades owing to their renewability, abundancy and remarkable physical and mechanical properties. The aim of this work was to investigate new strategies for surface modification and functionalization of nanocelluloses and their subsequent incorporation in polymer-host matrices. LÄS MER

  5. 4. Surface Modification of Cellulose by Covalent Grafting and Physical Adsorption for Biocomposite Applications

    Författare :Carl Bruce; Eva Malmström; Anna Carlmark; Linda Fogelström; Youssef Habibi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

    Sammanfattning : There is an increasing interest to replace fossil-based materials with renewable alternatives. Cellulose fibers/nanofibrils (CNF) are sustainable options since they are biobased and biodegradable. In addition, they combine low weight with high strength; making them suitable to, for example, reinforce composites. LÄS MER
