PA膜是一种新型的高分子材料,当它在某一特定方向上拉伸到某一程度时会出现电和光学上的各向异性。PA膜通过掺杂某种元素(如碘)可制成有机半导体,已有人把PA膜制成高效能大容量的电池材料。本文介绍对以稀土元素为催化体系的近二百个PA膜作透射和扫描电镜的形态结构观察分析,以及对部分样品作X射线粉晶衍射分析等情况,具体步骤是:把PA膜放在浓盐酸(10%～15%)和乙醇(85%～90%)的混合液中浸泡数小时,然
PA film is a new type of polymer material that exhibits electrical and optical anisotropy when it is stretched to a certain degree in a particular direction. PA film by doping certain elements (such as iodine) can be made of organic semiconductors, PA membranes have been made into high-performance high-capacity battery materials. In this paper, the morphology and structure of nearly two hundred PA films with rare earth element as catalytic system were observed and analyzed by transmission electron microscopy and X-ray powder diffraction analysis of some samples. The specific steps were as follows: Concentrated hydrochloric acid (10% ~ 15%) and ethanol (85% ~ 90%) mixed solution for several hours, then
