ConspectusSince the ground-breaking achievement of successfully exfoliating single-layer graphene in 2004, there has been significant and rapid development field two-dimensional (2D) nanomaterials. In materials science, 2D nanomaterials are defined as freestanding nanomembranes with a thickness below 100 nm other lateral dimensions that can extend to millimeter scale or beyond. These exhibit exceptional mechanical, physical, chemical properties due their extremely high surface area volume ratios, surpassing those bulk counterparts. As result, numerous top-down bottom-up methods have emerged over past decades synthesize novel nanomaterials, catering diverse applications. this Account, we review existing methods, such mechanical compression exfoliation, well including hydrothermal induction/solvothermal synthesis, vapor deposition etc. We critically discuss advantages limitations each method. Subsequently, highlight our recently developed method known polymer buckling enabled exfoliation (PSBEE). Unlike previous synthesis techniques, PSBEE is based on reaction between metals polymers fabricate unique nanostructures. This approach offers simple, efficient, cost-effective, environmentally friendly means achieving large-scale production featuring an size ratio ranging from 106 107. Notably, eliminates need for etching enables precise control morphology synthesized allowing transitions 1D nanotubes. Through thermal annealing, some PSBEE-fabricated gold undergo pyrolysis transform into 0D nanoparticles. Furthermore, versatility extends beyond metallic ceramic showcasing its broad applicability across material systems. The nanostructures usually network nanosized ceramics metals, contribute functional properties. include outstanding elastic strain limit, superb strength, remarkable plasticity, superior fracture toughness, electrocatalytic properties, triboelectric performance. Consequently, these lead applications sensing electrocatalysis. At same time, also notable terms scalable production, throughput efficiency, low energy consumption, making it highly suitable future industrial general, polymer-based fabrication opens up possibilities producing technologically leading new avenues various practical
