  2. 11. Thermodynamic Toolkit for Chemical Recycling to Monomer

    Author : Linnea Cederholm; Karin Odelius; Minna Hakkarainen; Peter Olsen; Louis Pitet; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; chemical recycling to monomer; polymerization thermodynamics; ring-opening polymerization; solvent effect; polyester; polycarbonate; copolymer; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The design of polymeric materials for a circular economy is, to a largeextent, a challenge of thermodynamics. The work presented in this thesishas explored the thermodynamic features of ring-opening polymerizationand ring-closing depolymerization, to develop polymeric materials andrecycling strategies for chemical recycling to monomer.

  4. 12. Towards compatibilization of cellulose nanofibrils in polymer matrices : Polymer design for mediating the nanofibril–matrix interface

    Author : Rosella Telaretti Leggieri; Eva Malmström; Mats Johansson; Catarina de Carvalho Esteves; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cellulose nanofibril CNF ; copolymer; nanocomposite; coating; reinforcement; interface; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Magnifying the nanostructure of wood reveals the features of an extraordinary nanocomposite material. In this nanocomposite, long fibrils of semicrystalline cellulose, with a cross-section in the nanometer range and length up to several micrometers, are embedded in an amorphous matrix made of other polymeric components.

  5. 13. Modification of microcapsules for controlled release

    Author : Markus Andersson Trojer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; block copolymer; coordination chemistry; polyelectrolyte multilayer; cross-linking; vibrational spectroscopy; electron paramagnetic resonance; imidazole; controlled release; colloidal stability; Microcapsule; quartz crystal microbalance with dissipation;

    Abstract : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. READ MORE

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

    Author : Baolin Guo; Ann-Christine Albertsson; Patric Jannasch; KTH; []
