Through sol-gel processing and electrospinning technique, extrathin fibers of poly(vinyl alcohol) (PVA)/lithium chloride/manganese acetate composite fibers were prepared. After calcination of the above precursor fibers at 600 degrees C, the spinel lithium manganese oxide (LiMn2O4) nanofibers, with a diameter of 100-200 nm, were successfully obtained. The fibers were investigated by TG-DTA, XRD, FT-IR, and SEM, respectively. The results showed that the crystalline phase and morphology of the fibers were largely influenced by the calcination temperature.
通过溶胶-凝胶工艺和静电纺丝技术，制备了聚（乙烯醇）（PVA）/氯化锂/醋酸锰复合纤维的超细纤维。将上述前驱体纤维在600℃下煅烧后，成功获得了直径为100-200nm的尖晶石型锂锰氧化物（LiMn2O4）纳米纤维。分别采用热重-差示热分析（TG-DTA）、X射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）和扫描电子显微镜（SEM）对纤维进行了研究。结果表明，煅烧温度对纤维的晶相和形貌有很大影响。
