This invention belongs to the field of inorganic nanofiber materials technology, specifically relating to a highly flexible boron nanofiber (BN) ceramic nanofiber and its preparation method. Using boric acid and melamine as main raw materials, this invention prepares the nanofiber through a complexation reaction, solution preparation, electrospinning, and heat treatment. The raw materials are inexpensive, the process is simple, and it is easy to scale up production. By heating the electrospinning needle at 90-120℃, the viscosity of the precursor needle tip is reduced, preventing premature crystallization of the complex and completely solving the needle clogging problem, ensuring continuous and stable spinning, and improving spinning efficiency and fiber quality. The resulting BN nanofibers are continuous, have uniform diameter, and a smooth surface. The controllable transformation from amorphous BN to highly crystalline hexagonal boron nitride can be achieved by adjusting the heat treatment temperature. The amorphous BN nanofiber felt has extremely low thermal conductivity (≤0.029 W / (m·K)) and excellent compression resilience, making it suitable as a reinforcement for composite materials or directly applicable in high-temperature filtration, high-efficiency heat insulation, and catalyst carriers.
