1. 1. 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.

3. 2. 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

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Poly L; L-lactide ; poly ε-caprolactone ; ring-opening polymerization; carboxyl-capped aniline trimer; carboxyl-capped aniline pentamer; coupling reaction; DCC DMAP system; degradability; electroactivity; conductivity; macromolecular architecture; tissue engineering; Polymer chemistry; Polymerkemi;

   Sammanfattning : The third-generation biomaterials are designed to stimulate specific cellular responses at the molecular level. Recent studies have shown that electrical signals regulate cellular activities including cell adhesion, migration, proliferation and differentiation. LÄS MER

5. 4. Designing Polymers for Biological Interfaces - From Antifouling to Drug Delivery

   Författare :Pontus Lundberg; Michael Malkoch; Anders Hult; Scott M. Grayson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

   Sammanfattning : Unspecific interactions, at the interface between a synthetic material and an aqueous biological environment, leading to irreversible protein adsorption can cause to undesired consequences. These include fouling of a boat hull or a triggered immune response. LÄS MER
