Sammanfattning : Melt Spun Piezoelectric Textile Fibres - an Experimental Study ANJA LUND Department of Materials and Manufacturing Technology Chalmers University of Technology ABSTRACT The manufacturing and characterisation of piezoelectric textile fibres are described in this thesis. A piezoelectric material is one that generates an electric voltage when deformed, a property which exists in a number of materials. LÄS MER
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.

Sammanfattning : This thesis explores the manufacturing and characterisation of melt spun electrically conductive polymer nanocomposites and piezoelectric textile fibres. Potential applications of these fibres are for example textiles with heating and sensor capabilities. LÄS MER
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
