Product Introduction

The multilayer accordion-like Ti₃C₂T_x is the first discovered Mxene material. It is produced through the selective etching of titanium aluminum carbide (Ti₃AlC₂) using hydrofluoric acid (HF). This process removes aluminum layers, resulting in the expansion and delamination of the remaining titanium carbide layers, which possess surface terminations denoted as T_x (such as -OH, =O, and -F). This etching process can be used to regulate the morphology and structure of two-dimensional materials, thereby influencing their properties and applications.

Our products ensure a clear accordion-like morphology and low aluminum content (≤2%) by adjusting the etching time and etching temperature in accordance with the raw material's size. They are suitable for scientific research, small to medium scale mass production and molded product research.

Product Characteristics

The product appears as a dark purple powder.
The product is a two-dimensional layered material with a multi-layer structure, where the layers are bonded by van der Waals forces.
The material is etched with HF, resulting in a clear accordion-like morphology.
The monolayer exfoliation method involves the use of intercalating agent combined with ultrasonic delamination.
The product is an excellent conductive material with a certain specific surface area.
The product has a long shelf life and should be stored in a vacuum or an inert environment.
