1. 16. Novel Porous Films from Functional and Biocompatible Linear-Dendritic Hybrids

   Författare :Marie V. Walter; Michael Malkoch; Steve P. Rannard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poly ethylene glycol ; poly caprolactone ; linear-dendritic hybrid; click chemistry; CuAAC; thiol-ene chemistry; amphiphilic polymer; honeycomb film; isoporous film; thiol; dendrimer;

   Sammanfattning : In the last decades, the fabrication of ordered nano- and microporous structures has attracted increasing interest due to their specific properties and multiple possible applications in electronics, as templates or in the biological field. The development of such materials has been favored by the introduction of the simple breath-figure templating method in the 1990’s. LÄS MER

   Nyckelord :Highly ionized pulsed magnetron sputtering; HPPMS; HPPIMS; thin film; plasma analysis; Langmuir probe; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The present thesis addresses two research areas related to film growth in a highly ionized magnetron sputtering system: plasma characterization, and thin film growth and analysis. The deposition technique used is called high power pulsed magnetron sputtering (HPPMS). LÄS MER

7. 20. Polymer Nanocomposites in Thin Film Applications

   Författare :Linda Fogelström; Anders Hult; José M. Kenny; KTH; []
   Nyckelord :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;

   Sammanfattning : 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.
