大尺寸2D材料绝缘导热和大电流密度析氢用的石墨辅助研磨剥离
Glue-Assisted Grinding Exfoliation of Large-Size 2D Materials for Insulating Thermal Conduction and Large-Current-Density Hydrogen Evolution
摘要：
二维（2D）材料具有许多有前途的应用，但其可规模化生产仍然具有挑战性。在此，我们开发了一种胶辅助研磨剥离（GAGE）方法，其中粘合剂聚合物作为胶水，以大规模生产具有大横向尺寸，高质量和高产量的2D材料。密度泛函理论模拟表明，剥离机理涉及到所选聚合物与二维材料的结合能之间的竞争，该竞争大于层状材料的剥离能。以h-BN为例，GAGE生产的2D h-BN平均横向尺寸为2.18 μm，厚度为3.91 nm。该方法还扩展到生产各种其他2D材料，包括石墨烯，MoS 2，Bi 2 O2 Se，蛭石和蒙脱石。由此产生的2D材料的两个代表性应用已经被证明，包括用于绝缘热传导的h-BN/聚合物复合材料和用于大电流密度析氢的MoS 2电催化剂，表明大规模生产的2D材料的巨大潜力。
英文摘要：
Two-dimensional (2D) materials have many promising applications, but their scalable production remains challenging. Herein, we develop a glue-assisted grinding exfoliation (GAGE) method in which the adhesive polymer acts as a glue to massively produce 2D materials with large lateral sizes, high quality, and high yield. Density functional theory simulation shows that the exfoliation mechanism involves the competition between the binding energy of selected polymers and the 2D materials which is larger than the exfoliation energy of the layered materials. Taking h-BN as an example, the GAGE produces 2D h-BN with an average lateral size of 2.18 μm and thickness of 3.91 nm. The method is also extended to produce various other 2D materials, including graphene, MoS2, Bi2O2Se, vermiculite, and montmorillonite. Two representative applications of thus-produced 2D materials have been demonstrated, including h-BN/polymer composites for insulating thermal conduction and MoS2 electrocatalysts for large-current-density hydrogen evolution, indicating the great potential of massively produced 2D materials.
