The superhydrophobicity of polyvinylidene fluoride (PVDF) membranes can be achieved by adding a small amount of hexagonal boron nitride nanosheets ( h-BNNSs) during the preparation process. The h-BNNSs can be fabricated by two steps of facile ultrasonication of commercial h-BN powders in water and subsequent centrifugation process. The introduction of a small amount of h-BNNSs into PVDF will result in structure and morphology changes of final PVDF membranes. The changes of the structure and morphology can significantly reduce the surface wettability of PVDF membranes, even generating superhydrophobicity. However, the superoleophilicity of PVDF membranes is well kept, which is not influenced by the introduction of h-BNNSs. The excellent superhydrophobicity and superoleophilicity make these porous h-BNNS/PVDF composites to be promising candidates for separating oil and water as membranes in practical oil-polluted waste water treatment.

Hexagonal boron nitride is often referred to as white graphene. This is a 2D layered material, with a structure similar to graphene. It has gained many applications in cosmetics, dental cements, ceramics etc. Hexagonal boron nitride is also used in medicine, as a drug carrier similar as graphene or graphene oxide. Here we report that this material can be exfoliated in two steps: chemical treatment (via modified Hummers method) followed by the sonication treatment. Afterwards, the surface of the obtained material can be efficiently functionalized with gold nanoparticles. The mitochondrial activity was not affected in L929 and MCF-7 cell line cultures during 24-h incubation, whereas longer incubation (for 48, and 72 h) with this nanocomposite affected the cellular metabolism. Lysosome functionality, analyzed using the NR uptake assay, was also reduced in both cell lines. Interestingly, the rate of MCF-7 cell proliferation was reduced when exposed to h-BN loaded with gold nanoparticles. It is believed that h-BN nanocomposite with gold nanoparticles is an attractive material for cancer drug delivery and photodynamic therapy in cancer killing.
