  1. 1. Dendrimers : Synthesis, Characterization and Use in Thiol-Ene Networks

    Author : Camilla Nilsson; Eva Malmström; Andreas Heise; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; polymer; molecular physics; Polymer chemistry; Polymerkemi;

    Abstract :  Dendrimers are perfectly branched, well-defined macromolecules with a layered structure and a large amount of peripheral end groups. The high functionality in combination with the possibility of dendrimers to adopt a globular shape at high molecular weights, gives them very unique properties. READ MORE

  2. 2. Dendrimers and dendronized polymers : synthesis and characterization

    Author : Andreas Nyström; Anders Hult; A. Dieter Schlüter; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dendrimers; dendronized polymers; atom transfer radical polymerisation; ring-opening metathesis polymerization; reversible addition-fragmentation chain transfer polymerization; 2; 2-bis methylol propionic acid; tri-block copolymers; rheology; differential scanning calorimerty; 1H-NMR self-diffusion; Polymer chemistry; Polymerkemi;

    Abstract : The goal of this work was to synthesize complex macromolecular architectures such as dendrimers and dendronized polymers, and evaluate the effect from the dendrons on the optical and material properties. The work presented in this doctoral thesis, Dendrimers and Dendronized Polymers - Synthesis and Characterization, is divided into one minor and one major part. READ MORE

  3. 3. Polyester dendrimers for biomedical applications

    Author : Patrik Stenström; Michael Malkoch; Javier de la Mata; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Dendrimers are perfectly defined and highly branched large molecules with a high density of functional groups that makes them interesting for a variety of biomedical applications such as drug delivery, theranostics and as antimicrobials. Their synthesis can be complicated, time-consuming and expensive which has been an obstacle to their success. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 5. Liquid crystalline polymers for nonlinear optics : pyroelectric polymers and ferroelectric dendrimers

    Author : Jonas Örtegren; KTH; []
    Keywords : ;

    Abstract : This thesis deals with liquid crystalline materialsincluding monomers, side-chain polymers, crosslinked polymers,and dendrimers. The materials are pyroelectric, meaning thatthere is a macroscopic electric polarization in the material,which is energetically stable in the absence of externalfields. READ MORE
