Monash University researchers have developed a scalable method for producing high-yield, defect-free monolayer 2D nanosheets using a technique called sticky mechanical exfoliation (SME). This process uses an ultra-viscous polymer (PEI) to protect the material during ball-milling, achieving over 90% monolayer content and 83% yield, producing nanosheets up to 2 microns long with excellent lattice quality. The technology enables efficient mass production of monolayer nanosheets from a bulk layered source, providing applications in various materials, including graphene and hexagonal boron nitride. The nanosheets can be stored dry with strong re-dispersibility, maintaining quality and monolayer integrity. This approach offers significant advantages for scalable manufacturing in fields requiring high-quality nanosheets.
