| Résumé : |
This research explains the melt spinning of bicomponent fibers which consist of a conductive polypropylene (PP) core and a sheath with piezoelee tric characteristics (polyvinylidene fluoride). Previously analyzed piezoelectric capabilities of polyvinylidene fluoride (PVDF) are to be exploited in sensor filaments. The fiber core is conductive due to a percolation CNT network in polypropylene. The sheath's piezoelectric effect is based on the formation of an all-trans conformation 13 phase, caused by draw-winding of the fibers. The core and sheath structure are characterized through wide-angle X-ray diffraction (WAXD). The distribution of CNTs in the polymer matrix, which affects the conductivity of the core, was investigated by transmission electron microscopy (TEM). Optical microscopy is used to determine the fibers' diameter regularity (core and sheath). The materials' viscosity is determined by rheometry. Eventually, an LCR tester is used to determine the core's specific resistance. |
