Thermal degradation of Pb(Zr0.53Ti0.47)O 3/poly(vinylidene fluoride) composites as a function of ceramic grain size and concentration

Journal Article


Abstract


  • Poly(vinylidene fluoride)/Pb(Zr0.53Ti0.47)O 3, ([PVDF]1-x/[PZT]x) composites of volume fractions x and (0-3) type connectivity were prepared in the form of thin films. PZT powders with average grain sizes of 0.2, 0.84, and 2.35 μm in different volume fraction of PZT up to 40 % were mixed with the polymeric matrix. The influence of the inorganic particle size and its content on the thermal degradation properties of the composites was then investigated by means of thermo-gravimetric analysis. It is observed that filler size affects more than filler concentration the degradation temperature and activation energy of the polymer. In the same way and due to their larger specific area, smaller particles leave larger solid residuals after the polymer degradation. The polymer degradation mechanism is not significantly modified by the presence of the inorganic fillers. On the other hand, an inhibition effect occurs due to the presence of the fillers, affecting particularly the activation energy of the process. © Akadémiai Kiadó, Budapest, Hungary 2013.
