  1. 6. Reprocessing and Characterisation of High Density Polyethylene Reinforced with Carbon Nanotubes

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Sofie Svensson; [2017]
    Keywords : HDPE; mechanical recycling; carbon nanotubes; nanocomposites;

    Abstract : Nanokomposit innehållande högdensitetspolyeten och kolnanorör återvanns och analyseradesför att undersöka hur materialets egenskaper påverkas av återvinning. Kompositenproducerades med 3 viktprocent kolnanorör och återvanns tio gånger genom att extrudera ochmala ner materialet. Analyser gjordes efter varje cykel av extrudering. READ MORE

  3. 7. Liquid Composite Molding of Multiphase Composites Using Resin with Nanofibrillated Cellulose : Distribution of Particles and Effect on Composite Properties

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mikael Westin; [2016]
    Keywords : ;

    Abstract : Two objectives have served as the basis for the present work. The first objective was to experimentally verify the output of a Monte Carlo-based model on particle deposition in porous structures (i.e. fiber preform) during the resin transfer molding (RTM) process. READ MORE

  4. 8. Investigation of the dielectric breakdown strength of polymer nanocomposites

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Mattias Karlsson; [2014]
    Keywords : breakdown; polyethylene;

    Abstract : The aim of this thesis is to investigate the possibility of enhancing the dielectric breakdown strength (DBS) of low density polyethylene (LDPE) with addition of voltage stabilizing additives. In the first part of the thesis, the influence of various process parameters on the alternating current DBS of pure LDPE and LDPE containing either 3 or 30 wt% magnesium oxide nanoparticles was investigated.

  5. 9. Controlled deposition and alignment of electrospun PMMA-g-PDMS nanofibers by novel electrospinning setups

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Bashar Haseeb; [2011]
    Keywords : Electrospinning; nanofibers; nanofiber alignment; PMMA-g-PDMS; controlled deposition; triple electrode.;

    Abstract : Electrospinning is a useful technique that can generate micro- and nano-meter sized fibers from polymer materials. Modification of the electrospinning parameters and apparatus can generate nanofibers for use in diverse applications ranging from tissue engineering to nanocomposite fabrication; however, electrospun fibers are typically collected in a random orientation and over large areas limiting their applications.

  6. 10. Hierarchical Micro- and Nanostructured Superhydrophobic Surfaces to Reduce Fibrous Encapsulation of Pacemaker Leads : Nanotechnology in Practical Applications

    University essay from Institutionen för fysik, kemi och biologi

    Author : Louise Carlsson; [2008]
    Keywords : ;

    Abstract : The purpose of this master’s thesis was to, by the use of nanotechnology, improve material properties of the biomedical polymer Optim™, used as the insulation of pacemaker leads. Improved material properties are required to reduce the extent of fibrous encapsulation of the leads. READ MORE
