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 کاملScalable exfoliation and dispersion of two-dimensional materials - an update.
The preparation of dispersions of single- and few-sheet 2D materials in various solvents, as well as the characterization methods applied to such dispersions, is critically reviewed. Motivating factors for producing single- and few-sheet dispersions of 2D materials in liquids are briefly discussed. Many practical applications are expected for such materials that do not require high purity formu...
متن کاملAcoustic Emission Monitoring for Ultrasonic Cavitation Based Dispersion Process
In the manufacturing of micro/nanocomposite materials, micro/nanoparticles need to be dispersed evenly into the base materials. However, due to their high surface-to-volume ratio and high surface energy, the micro/nanoparticles tend to agglomerate and cluster together. Ultrasonic cavitation is effective to disperse micro/nanoparticles. However, works on correlating the cavitation parameters wit...
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 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.
