由于二维材料的独特性质及其在电子学和储能器件中的应用，二维材料的剥离/分散具有重要意义。在本文中，我们解决了以可扩展和环境友好的方式分散2D材料的挑战。介绍了一种使用绿色分散剂纳米原纤化纤维素（NEC）在水溶液中有效分散2D材料[氮化硼（BN）和二硫化钼（MOS 2）]的方法。稳定的高浓度BN/MoS 2水溶液允许形成多功能复合材料，并且可以促进卷对卷制造。用BN溶液制备了具有优异机械强度的薄膜和纤维。此外，制备了坚固且柔性的MoS 2膜并用作钠离子电池的阳极，表明了柔性电池的应用。(C)2015爱思唯尔有限公司版权所有。
The exfoliation/dispersion of two-dimensional (2D) materials is of great importance due to their unique properties and applications in electronics as well as energy storage devices. In this paper, we address the challenge of dispersing 2D materials in a scalable and environmentally friendly way. A methodology to efficiently disperse 2D materials [boron nitride (BN) and molybdenum disulfide (MOS2)] in an aqueous solution using a green dispersant, nanofibrillated cellulose (NEC), was introduced. The stable high concentration BN/MoS2 aqueous solutions allow the formation of multifunctional composites and may facilitate roll-to-roll manufacturing. Films and fibers with excellent mechanical strength were fabricated with the BN solution. Additionally, strong and flexible MoS2 films were prepared and used as anodes for sodium ion batteries, indicating flexible battery applications. (C) 2015 Elsevier Ltd. All rights reserved.
