  • Capacitance-pressure (C-p) and resistance-pressure (R-p) relationships for the ferroelectric eopolymer poly (vinylidenefluoride/trifluoroethylene), P(VDF-TrFE) (80/20 mol%) at room temperature up to 14 GPa were investigated in a diamond anvil cell (DAC) using capacitance and resistance measurements. These results indicate that P(VDF-TrFE) with 80 mol% VDF undergoes two phase transitions below 14 GPa. The first apparent transition occurs near 1.1 GPa and the second apparent transition which is more sharply defined occur in the 5 to 6 GPa range.
