Abstract: Disclosed is a method of purifying boron nitride nanotubes through a simplified process. Specifically, the method includes preparing a starting solution containing boron nitride nanotubes (BNNTs), a dispersant and a solvent, centrifuging the starting solution or allowing the starting solution to stand to collect a supernatant, adding an acid to the supernatant and filtering a resulting product.
