Fluidic micelles and reverse micelles have served as exfoliation mediums. However, an additional force, such as extended sonication, is required. Gelatinous cylindrical micelles that are formed once desired conditions are achieved can be an ideal medium for the quick exfoliation of 2D materials without the need for any external force. The quick formation of gelatinous cylindrical micelles can rip off layers from the 2D materials suspended in the mixture leading to the quick exfoliation of 2D materials.
Herein, we introduce a quick universal method capable of delivering high-quality exfoliated 2D materials cost-effectively using CTAB-based gelatinous micelles as an exfoliation medium. The approach is devoid of harsh treatment, such as prolonged sonication and heating, and a quick exfoliation of 2D materials is completed using this approach.
We successfully exfoliated four 2D materials (MoS, Graphene, WS, and BN) and investigated their morphology, chemical, and crystal structure along with optical and electrochemical properties to probe the quality of the exfoliated product. Results revealed that the proposed method is highly efficient in exfoliating 2D materials in a quick time without causing any significant damage to the mechanical integrity of the exfoliated materials.
胶态胶束和反胶束已被用作剥离介质。然而，需要额外的力，如延长超声处理。一旦达到所需的条件，就会形成凝胶状的圆柱形胶束，对于无需任何外力的二维材料的快速剥离，它可以成为一种理想的介质。凝胶状圆柱形胶束的快速形成可以从悬浮在混合物中的二维材料上剥落层，从而快速剥离二维材料。
在这里，我们介绍了一种快速通用的方法，使用基于 CTAB 的凝胶状胶束作为剥离介质，可以有效地提供高质量的剥离二维材料。该方法不包括苛刻的处理，如长时间的超声处理和加热，并且可以使用该方法快速剥离二维材料。
我们成功地剥离了四种二维材料（MoS、石墨烯、WS 和 BN），并研究了它们的形貌、化学和晶体结构以及光学和电化学性质，以探究剥离产物的质量。结果表明，该方法在快速时间内高效地剥离二维材料，而不会对剥离材料的机械完整性造成任何显著损害。
