3. 2. Amphiphilic Polymers as Additives in Biomedical Polyurethanes. Surface Properties and Morphology

   Författare :Maria Kober; Centrum för analys och syntes; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymer micelles; phase separation; migration; poly ethylene oxide ; surface enrichment; morphology; polyurethane; additives; Surface modification; amphiphilic polymers; polymer blends; Polymer technology; biopolymers; Polymerteknik;

   Sammanfattning : The aim of this work was to achieve surface modification of two biomedical polyurethanes and one poly(urethane urea) through the addition of small amounts of amphiphilic copolymers in solution. The matrix polymers used were the poly(ether urethane)s Pellethane 2363-80AE (P80) and 2363-75D (P75) and a poly(ether urethane urea) similar to Biomer (PUUR). LÄS MER

4. 3. Thiol-Ene CHemistry and Dopa-Functional Materials towards Biomedical Applications

   Författare :Kristina Olofsson; Anders Hult; Michael Malkoch; Anders Daugaard; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Thiol-ene chemistry; DOPA; biomedical; UV; Fiber- och polymervetenskap; Fibre and Polymer Science;

   Sammanfattning : Thiol-ene chemistry is versatile and efficient and can be used as a powerful tool in polymer synthesis. In this thesis, the concept of thiol-ene chemistry has been central, where it has been explored as a tool for the synthesis of well-defined hydrogels and dopa-functional materials towards biomedical applications; such as hydrogels, primers for adhesive fixation of bone fractures, self-healing gels, and micelles for drug-delivery.

5. 4. Exploring Amphiphilic PEGMA-Based Architectures as Nanoparticles for Drug Delivery

   Författare :Christian Porsch; Eva Malmström Jonsson; Steve Rannard; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Sammanfattning : Within the last decades, the stated potential of polymer constructs as drug delivery systems have challenged researchers to develop sophisticated polymers with tunable properties. The versatility of polymers makes them highly attractive to tailor nanoparticles (NPs) which fulfill the demands of effective drug delivery systems (DDS). LÄS MER

7. 5. Surface Modification of Cellulose-based Materials for Tailoring of Interfacial Interactions

   Författare :Simon Utsel; Lars Wågberg; Simon Biggs; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The awareness of our need for a sustainable society has encouraged the search for renewable, high quality materials that can replace oil-based products. This, in combination with increased competition in the forest industry, has stimulated a lot of research into different types of wood-based materials where cellulose-rich fibers are combined with different types of polymers.
