Glue-assisted grinding exfoliation of large-size 2D materials for insulating thermal conduction and large-current-density hydrogen evolution

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 glue to massively produce 2D with large lateral sizes, high quality, and yield. Density functional theory simulation shows that mechanism involves competition between binding energy of selected polymers is larger than layered materials. Taking h-BN an example, GAGE produces average size 2.18 ?m thickness 3.91 nm. The also extended various other materials, including graphene, MoS2, WS2, Bi2O2Se, mica, vermiculite, montmorillonite. Two representative applications thus-produced been demonstrated, h-BN/polymer composites for insulating thermal conduction MoS2-based electrocatalysts large-current-density hydrogen evolution, indicating great potential produced
