【摘要】 以ES复合纤维为原料,采用干法成网、热风粘合工艺制得多孔非织造电池隔膜基布,然后采用磺化处理方法对基布进行亲水改性处理,并用SEM、FTIR等手段对隔膜了结构和性能进行了表征,最终得出电池隔膜的最佳磺化改性工艺。更多还原

【Abstract】 In this paper,a kind of nonwoven fabrics composed of polyethylene/polypropylene shealth/core fibers (ES fibers) was made by dry-web forming and through-air bonding process as a base material of battery separators. The base nonwoven materials were treated with concentrated sulfuric acid to improve the hydrophilic property. The properties of the treated materials as battery separators,such as the absorbing rate and volume of alkali solution,the alkali resistance property,were tested and the structure were investigated by SEM and FTIR. It is found that the optimal sulfonation treatment time for ES nonwoven fabrics is about 20 minutes under room temperature.更多还原
