摘　　要：以氮化硼纤维平纹布为载体,用前驱体转化法在平纹布内部均匀复合纳米氧化镁颗粒,制备出了氮化硼纤维基复合隔膜。用SEM、厚度测试、热处理、TG-DSC、电解液吸附能力测试等手段研究了复合隔膜的结构、稳定性及电解液吸附能力。研究表明:所制备的复合隔膜结构致密,厚度为300μm左右,内部均匀复合纳米氧化镁颗粒,具有良好的高温稳定性能。复合处理工艺能够显著提高隔膜的电解液吸附能力和保持能力,电解液吸附率达160%以上。Nano MgO particles modified boron nitride fiber based composite separator was prepared by using precursor conversion technology with boron nitride fiber plain cloth as supporting membrane. The structure, stability and the electrolyte adsorption ability of the composite separator were studied. The structure of the separator is compact, the thickness is about 300 μm, Nano MgO particles were uniformly distributed in the inner part of the separator. The separator has good thermal dimensional stability. The combined treatment could significantly improve the electrolyte adsorption and retention capacity of the separator, the electrolyte adsorption rate of the separator is above 160%.
