Abstract

High performance polymer-ceramic composites are presented as promising candidates for high temperature piezoelectric sensing applications. lead-titanate (PT) ceramic particulate is incorporated into a polyetherimide polymer matrix, (PEI) at a specific volume fraction of 20% in the forms of 0-3 and quasi 1-3. A conventional dielectrophoretic structuring is used to induce chain like particle configuration, followed by curing the matrix to form free standing films. Poling process is perfomed at temperatures above the Tg of the partially imidized matrix and under high voltages subsequently. Free standing composites are imidized at 200 °C and 300 °C to form fully imidized films. The poled particulate composites tend to retain the original piezoelectric properties upon fully imidization. The structured composites show enhanced dielectric and piezoelectric properties compared to 0-3 composites.
