Hexagonal Boron Nitride, Wettability, Roughness, Liquid-phase Exfoliation


Hexagonal boron nitride (h-BN) is a 2D material with excellent properties, such as large band gap, high thermal and chemical stability, transparency, and high resistance to oxidation and corrosion. These properties make h-BN a suitable candidate to be used in the development of advanced coatings. However, as for other nanomaterials, tailor and control the properties of h-BN is a fundamental key for their application into several fields. Here, the wetting properties of h-BN when is exfoliated by ultrasonic cavitation in different solvents including isopropyl alcohol (IPA), dioxane (Dx), N-methyl pyrrolidone (NMP) and dimethyl formamide (DMF) were investigated. The wetting properties of the different h-BN materials were determined by measuring the water contact angle (WCA) of h-BN thin films deposited on silicon dioxide, different contact angles were observed for each sample, the different WCA values are explained by the differences in the structure and roughness of the thin film surfaces obtained just by changing the solvent during exfoliation. These surface properties were characterized by optic and transmission electronic microscopy (TEM) as well as atomic force microscopy (AFM).
