  1. 6. Cu(I) stabilizing polymers for marine anti-fouling applications

    Författare :Alireza Movahedi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; coordinating polymers; copper; anti-fouling coatings; CuAAC; triazole; epoxide.; polymer functionalization; click chemistry;

    Sammanfattning : The growth of marine organisms on immersed surfaces in seawater is known as biofouling and causes several problems for marine transportation. The need to combat fouling is thus of great importance. Copper has to be used in extreme amounts to act as an efficient biocide. LÄS MER

  3. 7. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

    Författare :Anna Finne; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; coordination-insertion; germanium; cyclic tin alkoxides; spirocyclic initiators; poly L-lactide ; poly 1; 5-dioxepan-2-one ; triblock; star-shaped; network; functionalization; morphology; AFM; Polymer chemistry; Polymerkemi;

    Sammanfattning : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. LÄS MER

  4. 8. Chemical Functionalization and Characterization of Cellulosic Materials

    Författare :Hanna de la Motte; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nuclear magnetic resonance; Crosslinking; High bulk networks; Cotton linters; Cationization; Nanocrystalline cellulose; Softwood kraft pulp; Characterization;

    Sammanfattning : Polysaccharides are the most abundant biopolymers produced in nature and belong, together with proteins and nucleic acids, to the main components of life. Polysaccharides are polyhydroxylic polymers that can be functionalized by a wide selection of chemical reactions, and modifications of these biopolymers are applicable in the development of new materials.

  5. 9. Functional Cyclic Carbonate Monomers and Polycarbonates : Synthesis and Biomaterials Applications

    Författare :Jonas Mindemark; Tim Bowden; Andrew Dove; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA condensation; gene delivery; ionomers; polyplexes; self-assembly; amphiphiles; biodegradable; biological applications of polymers; transfection; cyclic carbonate monomers; polycarbonates; semicrystalline polymers; click chemistry; triazoles; cycloaddition; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : The present work describes a selection of strategies for the synthesis of functional aliphatic polycarbonates. Using an end-group functionalization strategy, a series of DNA-binding cationic poly(trimethylene carbonate)s was synthesized for application as vectors for non-viral gene delivery. LÄS MER

  7. 10. Recombinant spider silk for biomedical applications - from functionalizing surfaces of synthetic materials to in vitro modelling of tissues
