Experimental study demonstrates large-scale liquid exfoliation of stable black phosphorus nanosheets in organic solvent, highlighting broad utility across photonics and composite materials.

Key Points

To synthesize ambient-stable, high-quality few-layer black phosphorus nanosheets in scalable quantities and demonstrate their practical utility beyond traditional electronic applications.
Exfoliated few-layer black phosphorus nanosheets via liquid phase exfoliation under ambient conditions using organic solvents, primarily N-cyclohexyl-2-pyrrolidone (CHP).
Characterized degradation kinetics and environmental stability using empirical exposure tests and complementary theoretical simulations across variable oxygen and water levels.
Tested the exfoliated nanosheets across functional applications, including ultrafast saturable absorbers, gas sensors, and structural reinforcement in composite materials.
Liquid exfoliation in CHP produced scalable, size-tunable, photoluminescent few-layer black phosphorus nanosheets protected against ambient degradation by a solvent-induced solvation shell.
Degradation reactions occurred exclusively at nanosheet edges, with reaction rates directly dependent on surrounding oxygen and water concentrations.
Demonstrated effective device integration and performance in ultrafast optical saturable absorbers, sensitive gas sensors, and mechanical fillers for composite reinforcement.
