Abstract
ABSTRACTThree‐phase polyamide 11 (PA 11)/lead zirconate titanate (PZT)/carbon nanotubes (CNT) composites are elaborated by extrusion. The influence of inorganic particles on the electrical properties of conductive composites and the influence of conductive particles on the ferroelectric properties of organic/inorganic composites are both studied. Inorganic particles do not modify the establishment of the electrical percolation path of CNTs either regarding the percolation threshold value or the conductivity reached above this insulator–conductive transition. The dielectric permittivity of two‐phase PA 11/PZT composites is improved with the addition of only 0.2% in volume of CNTs. This three‐phase composite could be proposed for actuation, energy harvesting and damping performances enhancement.
