摘要/Abstract

摘要： 本论文采用硼酸和三聚氰胺按照一定的配比合成氮化硼的前驱体高聚物,氮化硼前驱体高聚物溶于甲酸溶液。将氮化硼前驱体高聚物在23 kV,正负极距离为15 cm条件下纺出细度均匀的纤维。对合成的前驱体高聚物放在马弗炉中按照10℃/min的升温速度升至800℃,保温一定时间得到氮化后的产物,氮化后产物成白色,硬度较大。利用扫描电镜、傅里叶红外光谱仪和TG-DSC热重分析仪对氮化后产物的性能特征进行了测试。

关键词: 硼酸;三聚氰胺;氮化硼前驱体;氮化/高聚物

Abstract: In this paper, boron nitride precursor polymer was synthesized by a certain ratio of boric acid and melamine,The boron nitride precursor polymer was dissolved in formic acid solution, and the boron nitride precursor was spinned in 23 kV,15 cm of the distance. And the fiber was uniform. The synthesis of precursor polymer was placed in a muffle furnace and then was heated to 800 ℃ according to 10 ℃/min of heating rate, and was held for a certain time, boron nitride product was made. Its colour is white and hardness is larger. The performance characteristics of the product were tested by using the Fourier transform infrared spectrometer, TG-DSC thermogravimetric analyzer and scanning electron microscope.

Key words: boric acid;melamine;precursor of boron nitride;nitride/polymer
