Abstract

To analyze X-ray diffraction patterns obtained from polyimide films subjected to external influence (uniaxial tension and exposure at liquid helium temperature), radial distribution function (RDF) curves were constructed and the geometry of the 4,4′-oxydiphenylene-pyromellitimide monomer (PM) was calculated. From the RDF analysis, it follows that uniaxial tension of PM polymer films leads to a change in the geometry of the monomer, and exposure at low temperatures leads to mutual ordering of the polymer chains.

无定形聚合物薄膜的结构研究：实验与计算

为了分析受到外部影响（单轴拉力和液氦温度下的暴露）的聚酰亚胺薄膜所获得的 X 射线衍射图样，我们构建了径向分布函数（RDF）曲线，并计算了 4,4′-氧二苯基吡喃亚胺单体（PM）的几何形状。从 RDF 分析中可以看出，PM 聚合物薄膜的单轴拉伸会导致单体的几何形状发生变化，而低温暴露则会导致聚合物链的相互有序化。

期刊介绍： Guided by an international editorial board, Low Temperature Physics (LTP) communicates the results of important experimental and theoretical studies conducted at low temperatures. LTP offers key work in such areas as superconductivity, magnetism, lattice dynamics, quantum liquids and crystals, cryocrystals, low-dimensional and disordered systems, electronic properties of normal metals and alloys, and critical phenomena. The journal publishes original articles on new experimental and theoretical results as well as review articles, brief communications, memoirs, and biographies. Low Temperature Physics, a translation of the copyrighted Journal FIZIKA NIZKIKH TEMPERATUR, is a monthly journal containing English reports of current research in the field of the low temperature physics. The translation began with the 1975 issues. One volume is published annually beginning with the January issues.
