Co-solvent exfoliation and suspension of hexagonal boron nitride

3 December, 2014 - 00:54

Chem. Commun., 2015, 51,187-190
DOI: 10.1039/C4CC07324J, CommunicationK. L. Marsh, M. Souliman, R. B. Kaner
A simple method is presented for exfoliating and suspending hexagonal boron nitride using a co-solvent approach. A 60 w/w% concentration of tert-butanol in water is very effective at exfoliating boron nitride especially when compared to the individual components alone as indicated by UV-vis and transmission electron microscopy. Molecular weight and surface tension are found to play inverse roles in the exfoliation.
