Extremely Efficient Liquid Exfoliation and Dispersion of Layered Materials by Unusual Acoustic Cavitation
Layered materials must be exfoliated and dispersed in solvents for diverse applications. Usually, highly energetic probe sonication may be considered to be an unfavourable method for the less defective exfoliation and dispersion of layered materials. Here we show that judicious use of ultrasonic cavitation can produce exfoliated transition metal dichalcogenide nanosheets extraordinarily dispers...
متن کاملExfoliation of layered rutile and perovskite tungstates.
The layered trirutile phases HMWO6 (M = Nb, Ta) and the layered perovskite H2W2O7 (synthesized by acid leaching of Bi2W2O9) were exfoliated into nanoscale colloids by reaction with quaternary ammonium hydroxides.
متن کاملToward the Systematic Control of the Exfoliation of Atomically Thin Layered Materials by Electrostatics
The debut of single and few-layer graphene (FLG) in the past decade has surprised the physics community and led to numerous research studies on 2D materials embodied as atomically thin layered materials (ATLMs). Beyond exceptional electronic conductivity, FLG presents various interesting physical properties, including interface-layer-independent heat transfer and wetting transparency. Despite t...
متن کاملHigh-efficiency exfoliation of layered materials into 2D nanosheets in switchable CO2/Surfactant/H2O system
Layered materials present attractive and important properties due to their two-dimensional (2D) structure, allowing potential applications including electronics, optoelectronics, and catalysis. However, fully exploiting the outstanding properties will require a method for their efficient exfoliation. Here we present that a series of layered materials can be successfully exfoliated into single- ...
متن کاملCryo-mediated exfoliation and fracturing of layered materials into 2D quantum dots
Atomically thin quantum dots from layered materials promise new science and applications, but their scalable synthesis and separation have been challenging. We demonstrate a universal approach for the preparation of quantum dots from a series of materials, such as graphite, MoS2, WS2, h-BN, TiS2, NbS2, Bi2Se3, MoTe2, Sb2Te3, etc., using a cryo-mediated liquid-phase exfoliation and fracturing pr...
