Description

technical field The invention relates to a liquid phase shearing device. Background technique Since the new century, graphene (Graphene) and molybdenum disulfide (MoS 2 ) has been a research hotspot all over the world, and their unique physical properties have been discovered one after another, such as the ultrafast electron transport and heat transport capabilities of graphene, single-layer or few-layer MoS 2 The optical response and radiation resistance properties caused by the unique energy level structure, etc., as far as the laboratory level is concerned, various new materials based on them have shown potential advantages in the fields of catalysis, energy and sensors, and have become the world's The key direction of each country's competing development. However, as far as the preparation of two-dimensional materials is concerned, their preparation has also gone through a relatively complicated process. Starting from the initial micromechanical exfoliation method, ion...

AI Technical Summary

Problems solved by technology

Conventional liquid phase shearing devices are divided into two categories: flat plate type and cylindrical type. The flat type means that the upper and lower plates are arranged in parallel, and the relative motion between the two plates is used to provide a velocity gradient, which is suitable for small batch research in laboratory systems. ;Cylindrical type uses the narrow space between the coaxial cylindrical surfaces, and the inner barrel rotates at high speed to provide a velocity gradient. Due to the large area, the power consumption and the stability of the device during high-speed shearing are relatively high, and the speed of the inner barrel is limited. Moreover, the process of shear peeling is a process of shear force doing work. Although the capacity between the two barrels can be achieved by increasing the height, the energy evenly distributed to the precursor of the layered substance is not large, resulting in the desired shear effect The yield is also limited
