我们制备了间同立构聚苯乙烯（SPS）薄膜，其ε晶相和沟道腔以高度规则性平行于薄膜厚度方向取向。此外，我们将苯胺分子引入到这些定向空腔中，并成功地将它们聚合成聚苯胺（PANI）。这是制备聚合物复合材料的温和而智能的方法，其中聚合物的取向和排列受到高度控制。这些 SPS/PANI 薄膜的电导率约为 0.05 S/cm，PANI 的最大分子量为 30 个苯胺单位。有趣的是，薄膜厚度增加了 110-200%。这是因为一些ε晶相是通过苯胺在空腔中聚合而连接起来的，就像缝纫珠（一些SPS ε晶相）与线（聚合PANI）一样。该论文研究了 SPS 薄膜中苯胺的反应温度以及聚苯胺的电导率、分子量和产率等其他性能。
We prepared the syndiotactic polystyrene (SPS) films such that its ε crystalline phase and its channeling cavity were oriented to be parallel to the direction of the film thickness with a high regularity. Moreover, we introduced aniline molecules to these oriented cavities and successfully polymerized them to polyaniline (PANI). This is the mild and intelligent way of preparing polymer composites where the orientation and arrangements of the polymers are highly controlled. These SPS/PANI films showed the electrical conductivity to be ~0.05 S/cm and the maximum molecular weight of PANI to be 30 units of aniline. Interestingly, the film thickness was found to increase by 110–200%. This is because some ε crystalline phase is connected by the polymerization of aniline in the cavity, like sewing beads (some SPS ε crystalline phase) with a thread (polymerizing PANI). The paper examined the reaction temperature of aniline in SPS films, and other properties such as conductivity, molecular weight, and yield of PANI.
