2. 16. Strategies to improve the aging, barrier and mechanical properties of chitosan, whey and wheat gluten protein films

   Author : Idoia Olabarrieta; Mikael Hedenqvist; Jose Maria Lagaron; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; biodegradable polymers; chitosan; whey protein; wheat gluten; poly ε-caprolactone ; montmorillonite; food packaging; permeability; mechanical properties; aging; pH; solubility; migration; solution casting.; Kemi; Chemistry; Kemi;

   Abstract : Chitosan, Whey Protein Isolate (WPI) and vital wheat gluten (WG) are three biomaterials that have quite promising properties for packaging purposes. They have good film forming properties and good gas barrier properties in dry conditions. READ MORE

4. 17. degradable electroactive polymers: Synthesis, Macromolecular architecture and scaffold design

   Author : Baolin Guo; Ann-Christine Albertsson; Patric Jannasch; KTH; []
   Keywords : Poly lactide ; poly ε-caprolactone ; ring-opening polymerization; carboxyl-capped aniline trimer; carboxyl-capped aniline pentamer; phenyl amino-capped aniline tetramer; coupling reaction; DCC DMAP system; degradability; electroactivity; conductivity; macromolecular architecture; chitosan; hydrogel; block copolymer; functionalization; oxidative coupling reaction; self-assembly; toxicity; tubular porous scaffold; neural tissue engineering.;

   Abstract : Electrically conducting polymers induce specific cellular responses at the molecular level. One of the crucial limitations of the use of conducting polymers in tissue engineering is their inability to degrade. READ MORE

5. 18. Large scale synthesis of polyesters with low amount of residual tin

   Author : Anna Stjerndahl; Ann-Christine Albertsson; Johan Lind; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer chemistry; Polymerkemi;

   Abstract : Användningen av resorberbara polymerer för applikationer inom vävnadsersättning har ökat markant under de senaste decennierna. Tekniken innebär att celler får växa på ett polymert bärarmaterial och på så sätt återskapa skadad vävnad, och är ett lovande alternativ till många av de implantat som används idag. READ MORE

6. 19. Graft polymerization

   Author : Torbjörn Lindberg; KTH; []
   Keywords : ;

   Abstract : This thesis is focused on morphological aspects of polymericsubstrates used in graft polymerization. Morphological changesof selected polymer systems were investigated in the virginstate and after irradiation, during the progress of graftpolymerization, in the final grafted state and duringsubsequent degradation.
