液晶苯酚酯相变的研究

STUDY ON LOW FREQUENCYINTERNAL FRICTION AND DSC MEASUREMENT FOR THE PHASETRANSITION OF LIQUID CRYSTAL CARBOXYLATE

用低频内耗及 Ｄ Ｓ Ｃ 方法研究了反４丁基环己基甲酸（４丙基） 环己基苯酚酯液晶的相变． 通过比较低频内耗与 Ｄ Ｓ Ｃ的激活能， 证实了液晶相变内耗峰的存在，

The phase transition ofliquid crystaltrans 4 (4’ propyleyclohexyl) phenyltrans 4 butylcy clohexane carboxylate was studied by Low frequency internal friction ( I F) m ethod and D S C. The resultsshowed that the I F peak is associated with phase transition by com paring the two active energies . Themechanism of P T I Fis due to formation of phase interface .
