  2. 1. Stabilizers in crosslinked polydimethylsiloxane

    Author : Kamyar Fateh-Alavi; KTH; []
    Keywords : Polymer; Material Science; Polydimethylsiloxane; Stabilizers;

    Abstract : The loss and recovery of the surface hydrophobicity areimportant phenomena when highvoltage insulators, with a shedmaterial composed of polydimethylsiloxane (PDMS), are used. Theloss of hydrophobicity is mostly due to the oxidativecrosslinking which takes place on the PDMS surface duringexposure to electrical discharges, e. g. corona discharges. READ MORE

  4. 2. Processing and properties of silane crosslinked wood-polyethylene composites

    Author : Göran Grubbström; Kristofer Gamstedt; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : Utilizing wood as filler and reinforcement in thermoplastic polymer-matrix composites, has gained interest during the last decades, mainly as profile extruded exterior building products such as deck boards, railings, and door- and window frame components. This thesis deals with silane-crosslinking of wood-polyethylene composites through reactiveextrusion. READ MORE

  5. 3. Exploring crosslinked networks of polymers and hybrid cellulose materials

    Author : Tobias Ingverud; Michael Malkoch; Lars Wågberg; Anders Egede Daugaard; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : The field of polymer chemistry has in recent decades had an immense development, resulting in new functional materials with groundbreaking applications. This has been driven partly by strong interdisciplinary alliances between the fields of medicine, biology, chemistry, and materials science. READ MORE

  6. 4. Ion-Crosslinked Nanocellulose Hydrogels for Advanced Wound Care Applications

    Author : Alex Basu; Natalia Ferraz; Pentti Tengvall; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofibrillated cellulose; wood nanocellulose; ion crosslinking; hydrogel; wound healing; biocompatibility; blood interactions; bacterial interactions; protein carrier; nanotherapeutic; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Abstract : A current trend in the field of wound care is the development of wound healing materials that are designed to address specific types of wounds or underlying pathologies to achieve improved healing. At the same time, there is a societal drive to replace synthetic materials with renewable alternatives. READ MORE

  7. 5. Interaction between Crosslinked Polyelectrolyte Gels and Oppositely Charged Surfactants

    Author : Peter Nilsson; Per Hansson; Ksenija Kogej; Uppsala universitet; []
    Keywords : Pharmaceutical chemistry; gel; polyelectrolyte; surfactant; deswelling; kinetics; phase separation; volume transition; ion-exchange; diffusion; liquid crystal; SAXS; cubic Pm3n; Farmaceutisk kemi;

    Abstract : The interactions between anionic, crosslinked gels and cationic surfactants have been investigated. When exposed to oppositely charged surfactant, the gel collapses into a dense complex of polyion and micelles. READ MORE
