  1. 6. degradable electroactive polymers: Synthesis, Macromolecular architecture and scaffold design

    Författare :Baolin Guo; Ann-Christine Albertsson; Patric Jannasch; KTH; []
    Nyckelord :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.;

    Sammanfattning : 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. LÄS MER

  3. 7. Engineering and Functionalization of Degradable Scaffolds for Medical Implant Applications

    Sammanfattning : This thesis demonstrates the use of electrospinning and the novel properties of electrospunmaterials in two fields.The microelectronics industry has identified thermal interface materials as one of themajor bottlenecks hindering further integration at packaging level. LÄS MER

  5. 9. Closed-loop strategy for valorization of starch : From starch to functionalized starch biomaterials and bioplastics

    Författare :Duo Wu; Minna Hakkarainen; Elisabetta Ranucci; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Starch; Nano-graphene oxide; Microwave; Valorization; Scaffold; Biomineralization; Bioplastics; Compatibilizer; Plasticizer; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The desire to utilize renewable resources and avoid wastes drives us to develop new concepts for material design. Non-edible starch feedstocks and starch bioplastic wastes were previously considered useless. LÄS MER

  7. 10. The role of computer-aided design and surface chemistry on Cell-scaffold interactions

    Författare :Sun Yang; Anna Finne-Wistrand; Ann-Christine Albertsson; Jinshan Pan; My Hedhammar; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; amorphous degradable copolymer; aliphatic polyester; 3D fiber deposition; computer-aided design; Tween 80; BMSC; hOB; porous scaffolds;

    Sammanfattning : Cell interactions and cell response to three dimensional scaffolds based on poly(L-lactide-co-1,5-dioxepan-2-one) [poly(LLA-co-DXO)] and poly(L-lactide-co-e-caprolactone) [poly(LLA-co-CL)] wereimprovedstudiedby increasing surface hydrophilicity and by using computer-aided scaffold design. Different amounts of Tween 80 (3, 10, 20 wt%) were mixed with the copolymer and it was found that the water contact angle decreased significantly with the amount of Tween 80. LÄS MER
