Abstract
Boron nitride nanotube (BNNT) dispersions and methods of fabricating the same are provided. Tip sonication-assisted hydrolysis can be utilized, with a dispersant/surfactant (e.g., polyvinyl alcohol (PVA)). The fabrication process can be used to obtain large scale BNNT dispersions with long term stability (e.g., stability for at least 3 months, at least 4 months, at least 5 months, at least 6 months, or about 6 months).
