摘要
研究了共聚物P（VDF－TrFE）（物质的量分数分别为80％、20％）在室温下、14GPa内的电容、电阻与压力的关系。实验结果表明，它在14GPa内存在两个相交：第一个相变发生在1．1GPa左右；而第二个相变发生在5～6GPa左右。
Capacitance-pressure (C-p)and resistance-pressure(R-p) relationships for the ferroelectric eopolymer poly (vinylidenefluoride/trifluoroethylene), P (VDF-TrFE) (80/20mol % ) at room temperature up to 14GPa were investigated in a diamond anvil cell (DAC) using capacitance and resistance measurements. These results indicate that P(VDF-TrFE)with 80 mold VDF undergoes two phase transitions below 14GPa. The first apparent transition occurs near 1. 1GPa and the second apparent transition which is more sharply defined occurs in the 5 to 6GPa range.
