Preparation method of perovskite type LaTiMeO3 fiber material
The invention relates to a perovskite type LaTiMeO3 fiber material preparation method, which comprises: (1) uniformly mixing a lanthanum chloride ethanol solution and a titanium tetrachloride ethanol solution according to a molar ratio of 1: 1, adding a chlorate, mixing, adding a complexing agent solution, and completely stirring for 2-3 h to obtain a LaTiMeO3 precursor sol; (2) carrying out electrostatic spinning on the LaTiMeO3 precursor sol by using an electrostatic spinning needle with the inner diameter of 0.2-3mm under the working conditions that the voltage is 8-20KV, the receiving distance is 15-25cm and the needle cylinder injection speed is 0.2-3ml/h, and receiving by using an aluminum foil to obtain a LaTiMeO3 fiber precursor; and (3) putting the LaTiMeO3 fiber precursor into an air dry oven, drying at 60-80 DEG C for 12-24 hours, and then putting the LaTiMeO3 fiber precursor into a high-temperature furnace at 600-850 DEG C for calcining for 4-8 hours to obtain the LaTiMeO3 fiber.
本发明涉及一种钙钛矿型LaTiMeO3纤维材料的制备方法，该制备方法包括以下步骤：(1)按照摩尔比1:1的比例将氯化镧乙醇溶液和四氯化钛乙醇溶液均匀混合，再加入氯化盐并混合，再加入络合剂溶液，充分搅拌2‑3小时，得到LaTiMeO3前驱体溶胶；(2)使用内径0.2‑3毫米静电纺丝针头，并在电压8‑20千伏、接受距离15‑25厘米、针筒推注速度0.2‑3毫升/小时的工况条件下对所述的LaTiMeO3前驱体溶胶进行静电纺丝，用铝箔接收，得到LaTiMeO3纤维前驱体；(3)将所述的LaTiMeO3纤维前驱体放入鼓风干燥箱中，在60‑80℃下干燥12‑24h，再放入600‑850℃的高温炉中煅烧4‑8h，得到LaTiMeO3纤维。
