TS和PTS单晶体的热刺激电流

THERMALLY STIMULATED DISCHARGE CURRENT OF TS AND ITS POLYMER PTS SINGLE CRYSTAL

测定了双(对甲基磺酸)2,4-己二炔-1,6-二醇酯(TS)及其不同聚合程度TS-PTS混合体和完全聚合的聚合物PTS在100-300K温度范围内的热刺激电流。在沿分子堆砌方向上(对PTS则是大分子链方向)上观察到了它们的热刺激电流,并在相应于它们相变152K和192K处呈现热刺激电流峰。研究了聚合程度对相变的影响,绘制了TS-PTS体系的相图。对另三个热刺激电流峰的归属作了定性解释。

The thermally stimulated discharge current of bis(p-toluene sulfonate) of 2,4-hexadiyne-1,6-diol (TS), TS-PTS blend and fully polymerized polymer PTS has been measured in the temperature range of 100 to 300 K. The peaks of current corresponding to their phase transitions at lower temperature in the direction parallel to the stacking were observed. The effect of polymerization on phase transitions was studied. The attribution of another three peaks of current was discussed qualitatively.
