4. 3. On the production of polyethylene dielectrics and conductive polymer composite fibres

   Författare :Martin Strååt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; carbon black; polypropylene; melt spinning; foaming; polystyrene; fibres; cables; carbon nanotubes; electrical properties;

   Sammanfattning : Foamed cable insulations and conductive polymer composite fibres are two applications in polymer processing where the electrical properties of a material may be altered significantly during processing. Their common denominator is that the outcome depends to a large degree on the flow behaviour of the polymer melt, in particular the melt extensional properties. LÄS MER

5. 4. Development and characterisation of bast and basalt fibre hybrid polymer composites for automotive applications

   Författare :Anjum Saleem; Roberts Joffe; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flax; Hemp; Kenaf; Basalt fibres; Polypropylene; Acrylic based polyester resins; Flexural; Tensile; Impact strength; Resource Recovery; Resursåtervinning;

   Sammanfattning : Natural fibres such as kenaf, hemp, and flax, also known as bast fibres, offer several benefits such as low density, low cost, carbon dioxide neutrality, sustainability and renewability. In Europe, their composites are used intensively by almost all car manufacturers, mostly in interior applications. LÄS MER

7. 5. Melt Spun Electro-Conductive Polymer Composite Fibers

   Författare :Azadeh Soroudi; Högskolan i Borås; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductive fibres; composites; blending; melt spinning; morphology; polyaniline; carbon nanotube; polypropylene; polyamide; draw-ratio; conductivity; Energi och material;

   Sammanfattning : One interesting approach is the development of conductive polymer composite fibers for innovative textile applications such as in sensors, actuators and electrostatic discharge. In this study, conductive polymer composite fibers were prepared using several different blends containing conductive components: a conjugated polymer (polyaniline-complex) and/or carbon nanotubes.
