  1. 1. 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

  3. 2. Multifunctional Dendritic Scaffolds: Synthesis, Characterization and Potential applications

    Författare :Yvonne Hed; Michael Malkoch; Mats Andersson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dendrimer; AB2C monomer; Click chemistry; CuAAC; thiol-ene coupling chemistry; TEC; linear dendritic hybrids; micelle; hydrogel; bone adhesive;

    Sammanfattning : The development of materials for advanced applications requires innovative macromolecules with well-defined structures and the inherent ability to be tailored in a straightforward manner. Dendrimers, being a subgroup of the dendritic polymer family, possess properties which fulfill such demands. LÄS MER

  4. 3. Synthesis and Properties of Branched Semi-Crystalline Thermoset Resins

    Författare :Hans Claesson; KTH; []
    Nyckelord :star-branched; semi-crystalline; comb-branched; ring-opening polymerization; poly ƒÕ-caprolactone ; dendritic; thermoset; low temperature curing; powder coating; UV-curing; poly 5; 5-dimethyl-1; 3-dioxane-2-one ; size exclusion chromatography; rheology;

    Sammanfattning : This thesis describes the synthesis and characterization ofbranched semi-crystalline polymers. Included in this work isthe SEC characterization of a series of dendrimers. Thebranched semi-crystalline polymers were synthesized in order toinvestigate the concept of their use as powder coatings resins. LÄS MER

  5. 4. Rheology and UV-curing of a star-branched polyester

    Författare :Hans Claesson; KTH; []
    Nyckelord :Powder coating; UV-curing; star-polymer; gel point; alipahtic polyester; rheology; dendritic;

    Sammanfattning : The use of powder coatings has increased steadily over thelast few decades. Their popularity is due to a number of majoradvantages they offer when compared to solvent-borne systems.Near zero VOC-content, reduced energy consumption and near 100%utilisation of the material are some of the advantages.

  7. 5. The synthesis of dendritic hydrogels and inorganic nanoparticles and their application as antibacterial and imaging materials

    Författare :Yanmiao Fan; Michael Malkoch; Annelie Brauner; Mauri Kostiainen; KTH; []
    Nyckelord :antibacterial hydrogels; dendritic polymers; dendrimers; silicon nanoparticles; cellulose nanofibrils; drug-resistant bacteria; wound dressings; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : AbstractThe overuse and misuse of conventional antibiotics has caused increased prevalence of drug-resistant bacteria, the infections of which cause high mortality and economic losses per year. It is therefore crucial to develop new technologies and treatments for infections caused by drug-resistant bacteria. LÄS MER
