To elucidate the nature of polyaniline (PANI)-GaSe mutual interaction, we carried out structural studies of nano-GaSe powders encapsulated by PANI, exploiting X-ray diffraction and high resolution transmission electron microscopy (HRTEM). Mechanically and ultrasonically dispersed GaSe crystals were mixed with aniline, which then underwent polymerization. After such treatment, GaSe nanocrystals (as shown by HRTEM) consist of few elementary monolayer sandwiches of hexagonal GaSe structure along the crystallographic axis c with a mean diameter of 9.2 nm. There was a significant expansion of interplanar distances (up to 0.833 nm) for all of the nanocrystals observed compared to 0.796 nm for the single crystals.
为了阐明聚苯胺（PANI）与 GaSe 相互作用的本质，我们利用 X 射线衍射和高分辨率透射电子显微镜（HRTEM）对被 PANI 包裹的纳米 GaSe 粉末进行了结构研究。通过机械和超声分散 GaSe 晶体与苯胺混合，然后进行聚合。经过这样的处理，GaSe 纳米晶体（如 HRTEM 所示）由沿晶轴 c 的几个基本单层六方 GaSe 结构组成，平均直径为 9.2nm。与单晶的 0.796nm 相比，所有观察到的纳米晶体的层间距离（高达 0.833nm）都有显著的膨胀。
