酞菁硅二醇进行固态聚合,其晶体颗粒聚合时在DSC谱图上出现吸热峰。当升温速率为20℃/分时,DSC的聚合量热曲线在420℃处出现吸热极大。在420℃的DSC恒温聚合曲线上,约一分钟后吸热量达到极大值。随恒温聚合温度的下降,吸热极大迅速右移。本文在光学显微镜的观察下对尺寸为10~(-1)mm数量级的单体、部分聚合产物、未掺碘聚合物及掺碘聚合物晶体颗粒的电导率进行了直接的测量。观察到未掺碘的聚合产物的本征电导率随聚合时间t而增大的关系式为:σ=2.20×10~(-6)—2.17×10~(-6)exp[1/37.3(t+2.5)]。掺碘聚合物晶体颗粒的电导率可达3×10~(-2)(Ωcm)~(-1)左右。本文还在偏光显微镜下观察到了掺碘使该聚合物晶体颗粒的尺寸增大并产生双折射条纹的现象。
The phthalocyanine silicon diol undergoes solid state polymerization, and the endothermic peak appears on the DSC spectrum during the polymerization of the crystal particles. When the heating rate is 20 ℃ / min, the DSC calorimetry curve appears to be extremely endothermic at 420 ℃. At 420 ° C DSC thermostatic polymerization curve, about one minute after the endothermic reached its maximum. As the temperature of the polymerization decreases, the endotherm moves rapidly to the right. In this paper, the conductivity of monomers, partially polymerized products, non-iodinated polymers and iodine-doped polymer crystal particles with sizes of 10-1 mm was measured directly under light microscope. It is observed that the intrinsic conductivity of the polymer product without iodine increases with the polymerization time t: σ = 2.20 × 10 -6 -6.17 × 10 -6 exp [1 / 37.3 ( t + 2.5)]. The conductivity of crystal particles doped with iodine can reach about 3 × 10 ~ (-2) (Ωcm) ~ (-1). In this paper, the phenomenon of iodine doping to increase the size of the polymer crystal particles and produce birefringent streaks was also observed under a polarizing microscope.
