ABSTRACT / САЖЕТАК:

2D-Pyrophyllite, a layered material with notable physico-chemical properties, is suitable for various applications, such as electrical insulator, protective coating or lubricant. Liquid-phase exfoliation (LPE) has emerged as a promising, large-scale, low-cost method for obtaining substantial yields of high-quality, basal plane defect-free pyrophyllite flakes in dispersion. Optimizing exfoliation conditions is crucial for achieving these objectives. After adjusting experimental parameters (initial concentration of bulk material, sonication time, solvent type, and centrifugation rate), a stable pyrophyllite dispersion with a high concentration of 98.8 µg/mL was obtained. The LPE method enables the production of high-yield flakes with well-defined shapes, flat surfaces, and regular edges.
