  1. 1. Prevention of Biofilm Formation on Silicone Rubber Materials for Outdoor High Voltage Insulators

    Författare :Sevil Atari Jabarzadeh; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High voltage insulator; silicone rubber; biofouling; biofilm; biocide; superhydrophobicity; self-cleaning; hierarchical roughness;

    Sammanfattning : Microbial colonization on the surface of silicone rubber high voltage outdoor insulators often results in the formation of highly hydrated biofilm that influence the surface properties, such as surface hydrophobicity. The loss of hydrophobicity might lead to dry band formation, and, in the worst cases, flashover and failure of the insulator. LÄS MER

  3. 2. Antimicrobial Polymer Composites for Medical Applications

    Författare :Peter Kaali; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; medical polymers; antimicrobial; body fluids; degradation; Polymer chemistry; Polymerkemi;

    Sammanfattning : The current study and discuss the long-term properties of biomedical polymers in vitro and invivo and presents means to design and manufacture antimicrobial composites. Antimicrobialcomposites with reduced tendency for biofilm formation should lead to lower risk for medicaldevice associated infection. LÄS MER

  4. 3. Tuning the long-term properties to control biodegradation by surface modifications of agricultural fibres in biocomposites

    Författare :Thorsak Kittikorn; Monica Ek; Ferruccio Doghieri; KTH; []
    Nyckelord :agricultural fibres; biocomposites; renewable polymers; PP; PLA; PHBV; surface modifications; water uptake; microbial growth; biodegradation;

    Sammanfattning : Sustainable polymeric materials put emphasis on mastering the whole life-cycle of polymeric materials. This includes the choice of raw materials, selection of synthesis and processing, environmental impact during long-term use followed by detailed knowledge about recycling and waste management. LÄS MER
