本文从用X射线衍射法测定聚酰亚胺薄膜结晶度出发,提出高聚物薄膜制品结晶度定量测定简便有效的一种方法和表观结晶度的概念。测定了美国和国产薄膜的结晶度,探索了结晶度与性能的关系。并对目前我国聚酰胺薄膜的生产工艺的改进和提高产品质量提供了理论依据。
Based on the determination of the crystallinity of polyimide films by X-ray diffraction, a method for the quantitative determination of crystallinity of polymer films and the concept of apparent crystallinity are proposed. The crystallinity of American and domestic films was measured and the relationship between crystallinity and properties was explored. At the same time, it provides a theoretical basis for the improvement of the production technology and the improvement of the product quality of the polyamide film in our country.
