我们开发了一种简便，大规模，和环境友好的液体剥离方法，以生产稳定和高浓度的分散体的单层到几层黑磷（BP）纳米片从散装BP使用九种离子液体。所制备的悬浮液在空气中放置一个月，无明显的沉降和聚集现象。特别地，在1-羟乙基-3-甲基咪唑鎓三氟甲磺酸盐（[HOEMIM][TfO]）中获得的BP纳米片的浓度（高达0.95 mg mL-1）是BP纳米片分散体中报道的最高浓度。该研究为绿色、大规模、高浓度制备原子级薄的BP纳米片并实现其原位应用提供了新的机遇。
We developed a facile, large-scale, and environmentally friendly liquid-exfoliation method to produce stable and high-concentration dispersions of mono- to few-layer black phosphorus (BP) nanosheets from bulk BP using nine ionic liquids. The prepared suspensions can stabilize without any obvious sedimentation and aggregation in ambient air for one month. In particular, the concentration (up to 0.95 mg mL–1) of BP nanoflakes obtained in 1-hydroxyethyl-3-methylimidazolium trifluoromethansulfonate ([HOEMIM][TfO]) is the highest reported for BP nanosheets dispersions. This work provides new opportunities for preparing atomically thin BP nanosheets in green, large-scale, and highly concentrated processes and achieving its in situ application.
