  2. 6. Towards a retro-structural design of degradable aliphatic polyester-based materials

    Author : Veluska Arias; Ann-Christine Albertsson; Minna Kellomäki; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrolysis; polyesters; polylactide; hydrophobicity; crystallinity; miscibility; nanoparticles; stereocomplex; homocomposites; Kemi; Chemistry;

    Abstract : The increasing amount of accumulated plastic waste has led to a continuous search for degradable materials for use in a variety of applications. This eco-friendly approach contemplates the use of degradable alternatives to the inert polymers (the main components in plastics) used today and further engineering of their degradation pathways.

  6. 9. Steric Stabilization of Polylactide particles achieved by Covalent 'grafting-from' with Hydrophilic Polymers

    Author : Robertus Wahyu Nayan Nugroho; Ann-Christine Albertsson; Karin Odelius; Anders Höglund; Mark Rutland; Martina Janstål; KTH; []
    Keywords : Steric stabilization; AFM; hydrophilicity; surface modification; poly lactide ; acrylamide; acrylic acid; maleic anhydride;

    Abstract : Despite numerous advantages of using particles in a wide range of applications, they have one drawback that is their tendency to agglomerate. One way to overcome this problem is to sterically  stabilize the particles by introducing polymeric  chains covalently attached to the surface. READ MORE

  7. 10. 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.
