  1. 1. Polymer Nanocomposites in Thin Film Applications

    Author : Linda Fogelström; Anders Hult; José M. Kenny; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanocomposites; hyperbranched polymers; montmorillonite; clay nanoparticles; exfoliated; coatings; crosslinking; TEM; XRD; mechanical properties; thermal properties; cellulose nanofibers; Atom Transfer Radical Polymerization; Ring-Opening Polymerization; poly ε-caprolactone ; surface modification; grafting; interfacial adhesion; Polymer chemistry; Polymerkemi;

    Abstract : The introduction of a nanoscopic reinforcing phase to a polymer matrix offers great possibilities of obtaining improved properties, enabling applications outside the boundaries of traditional composites. The majority of the work in this thesis has been devoted to polymer/clay nanocomposites in coating applications, using the hydroxyl-functional hyperbranched polyester Boltorn® as matrix and montmorillonite clay as nanofiller.

    Abstract : 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. READ MORE

  4. 4. Thermally cured coil-coatings utilizing novel resins and fatty acid methyl esters as reactive diluents

    Author : Katarina Johansson; Mats Johansson; Rolf van Benthem; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coatings; Coil-coatings; Thermal cure; Reactive diluents; Fatty acids; Transesterification; Hyperbranched polyester resins; Film properties; Polymer chemistry; Polymerkemi;

    Abstract : Solvent-borne thermally cured coil-coating resins contain large amounts of volatile organic solvents in order to obtain suitable flow for film application. This work describes how the expensive and environmental hazardous volatile organic solvent content of a solvent-borne thermally cured polyester/melamine coil-coating system can be reduced by introduction of fatty acid methyl esters (FAMEs) as reactive diluents and modification of the polyester binder resin.
