摘要
采用等温浸渍法，在温度313 K ~ 433 K、频率200 hz ~ 2 kHz范围内，对共混比为1:5、1:2、1:1、2:1和5:1的PMMA:PVAc共混物薄膜进行了交流电导率测量。在所研究的所有共混物中，交流电导率在所有频率下的温度依赖性都显示出随着频率的增加而向更高温度方向移动的峰值。交流电导率也随频率的增加而增加。试图解释所观察到的行为，并了解在PMMA:PVAc共混物的传导。
AC conductivity measurements on PMMA:PVAc polyblends
ac Conductivity measurements on thin films of PMMA:PVAc polyblends (blend ratio-1:5, 1:2, 1:1, 2:1 and 5:1), grown by isothermal immersion technique, have been carried out in the temperature range 313 K to 433 K and frequency range 200 Hz-2 kHz. The temperature dependence of ac conductivity at all the frequencies, in case of all the blends studied, shows a peak which shifts towards higher temperature with increase in frequency. The ac conductivity has also been observed to increase with frequency. An attempt to explain the observed behaviour and to understand the conduction in PMMA:PVAc polyblends has been made.
