利用X射线能谱(EDX)分析可以确定不同条件下粘接接头内胶黏剂的元素组成及其变化行为。由于胶黏剂和聚酰亚胺薄膜组成成分不同,可以利用X射线能谱计算出胶黏剂的热失重率,从而计算出聚酰亚胺薄膜粘接接头内胶黏剂的热分解动力学,并和空气环境下胶黏剂热分解活化能进行比较,表明粘接接头内胶黏剂的热分解速率低于空气环境下胶黏剂热分解速率。这种分析测试方法为原位表征粘接接头的性能提供了一种新的分析方法。
X-ray energy dispersive spectroscopy (EDX) analysis can determine the elemental composition and the changing behavior of the adhesive in the adhesive joint under different conditions. Due to the different composition of the adhesive and the polyimide film, the thermal weight loss rate of the adhesive can be calculated by X-ray energy spectrum to calculate the thermal decomposition kinetics of the adhesive in the polyimide film adhesive joint , And compared with the thermal decomposition activation energy of the adhesive in air environment, indicating that the thermal decomposition rate of the adhesive in the adhesive joint is lower than that of the adhesive in the air environment. This analytical test method provides a new analytical method for characterizing the properties of adhesive joints in situ.
