【摘要】：聚酰亞胺具有優(yōu)良的力學性能、耐熱性能及化學穩(wěn)定性能,其多孔薄膜材料是動力鋰離子電池隔膜的最佳選擇之一,但以碳酸鈣為致孔劑經過聚酰亞胺/碳酸鈣復合薄膜選擇性去除技術制備的多孔聚酰亞胺材料呈脆性,為了探索其力學性能欠佳的原因,本文對以碳酸鈣為致孔劑的相關聚酰亞胺材料進行了XRD、紅外光譜研究和分析。研究結果顯示:XRD、紅外光譜都能夠證明使用1∶1鹽酸溶液可以去除聚酰亞胺/碳酸鈣復合材料中的碳酸鈣成分,紅外光譜還揭示碳酸鈣的加入,使得聚酰亞胺材料的亞胺化程度只能達到80%。
[Abstract]:Polyimide has excellent mechanical properties, heat resistance and chemical stability. Its porous film material is one of the best choice for the diaphragm of power lithium ion battery. However, the porous polyimide material prepared by selective removal of polyimide / calcium carbonate composite film with calcium carbonate as pore-forming agent is brittle, in order to explore the reasons for its poor mechanical properties. In this paper, the related polyimide materials with calcium carbonate as pore-forming agent were studied and analyzed by XRD and IR spectra. The results showed that: XRD. The infrared spectra can show that the polyimide / calcium carbonate composites can be removed by using 1: 1 hydrochloric acid solution, and the addition of calcium carbonate is also revealed by the infrared spectrum. The degree of imidification of polyimide materials can only reach 80%.
