  1. 1. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

    Author : Anna Finne; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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. READ MORE

  2. 2. Cation Conduction and Coordination in Carbonyl-Containing Compounds : Li+ Transport in Alternative Polymer Electrolyte Host Materials

    Author : Therese Eriksson; Daniel Brandell; Jonas Mindemark; Claudio Gerbaldi; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Solid polymer electrolytes; Lithium ion batteries; Ion transport; Polyester; Polycarbonate; Polyketone; Ion coordination; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The field of solid polymer electrolytes (SPEs) used to create safer lithium-ion batteries has been dominated by polyethylene oxide (PEO) since the discovery of its ion-conducting properties in the 1970s. In this thesis, as an alternative, the ion coordination and conduction properties of SPEs based on polyketones, polyesters and polycarbonates are investigated. READ MORE

  3. 3. Bioresorbable copolymers with tailored properies : innovative materials för soft tissuel engineering

    Author : Natalia Andronova; Ann-Christine Albertsson; Pieter Dijkstra; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; poly 1; 5-dioxepan-2-one ; poly ε-caprolactone ; poly L-lactide ; poly trimethylene carbonate ; triblock; network; cyclic tin alkoxide; controlled coordination-insertion ring-opening polymerization; thermoplastic elastomers; Polymer chemistry; Polymerkemi;

    Abstract : The emerging need for new synthetic materials for soft tissue engineering applications encourages the search for innovative polymers having interesting properties. Ring-opening polymerization of lactones and lactides initiated by tin alkoxides has received particular attention due to the versatility of the method for building up well-defined biodegradable structures.

  4. 4. Injectable Composite Hydrogels Based on Metal-Ligand Assembly for Biomedical Applications

    Author : Liyang Shi; Jöns Hilborn; Dmitri Ossipov; Wenxin Wang; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; injectable; hydrogel; shear-thinning; self-healing; coordination chemistry; biomedical applications;

    Abstract : This thesis presents new strategies to construct injectable hydrogels and their various biomedical applications, such as 3D printing, regenerative medicine and drug delivery. These hydrogels cross-linked by dynamic metal-ligand coordination bonds exhibit shear-thinning and self-healing properties, resulting in the unlimited time window for injection. READ MORE

  5. 5. Understanding the mechanisms behind atom transfer radical polymerization : exploring the limit of control

    Author : Helena Bergenudd; Mats Jonsson; Eva Malmström Jonsson; David M Haddleton; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; polymerization; controlled radical polymerization; atom transfer radical polymerization; kinetics; catalysis; electrochemistry; Polymer chemistry; Polymerkemi;

    Abstract : Atom transfer radical polymerization (ATRP) is one of the most commonly employed techniques for controlled radical polymerization. ATRP has great potential for the development of new materials due to the ability to control molecular weight and polymer architecture. READ MORE
