Description
Single-Layer Titanium Carbide Ti₃C₂Tₓ MXene Colloidal Dispersion (1 mg/mL)
This product is a single-layer Ti₃C₂Tₓ MXene dispersion, consisting of exfoliated two-dimensional titanium carbide nanosheets suspended in water at a concentration of 1 mg/mL. The suspension appears as a dark green, high-purity colloid and contains fully delaminated flakes that exhibit exceptional electrical conductivity, rapid surface reactivity, and a large accessible surface area.
Because each sheet is individually separated rather than stacked, the monolayer morphology ensures uniform performance, making this material ideally suited for applications that require highly responsive 2D surfaces, such as printed electronics, electrochemical sensing, energy-storage devices, and multifunctional coatings. Its dispersibility and structural integrity provide researchers and engineers with a reliable platform for both experimental development and industrial formulation.
What This Material Is
Single-layer Ti₃C₂Tₓ is a member of the MXene family—a group of two-dimensional transition-metal carbides derived from selective etching of layered MAX phases. As a fully exfoliated MXene, it contains individual, atomically thin nanosheets rather than multilayer stacks, enabling exceptional conductivity and fast interfacial kinetics. Surface termination groups (Tₓ), including –O, –OH, and –F, further tune its reactivity and compatibility with various matrices.

Applications
1. Energy Storage & Electrodes
Single-layer Ti₃C₂Tₓ nanosheets offer outstanding electrical conductivity and large accessible surface area, improving ion transport and charge storage in supercapacitors, Li-ion and Na-ion batteries, and hybrid energy-storage devices.
2. Conductive Inks, Coatings & EMI Shielding
The stable low-concentration suspension can be formulated into printable conductive inks, thin antistatic coatings, transparent conductive films, and EMI-shielding layers, widely used in flexible and wearable electronics.
3. Sensors & Biosensing Devices
Its atomically thin structure and surface terminations support fast electron transfer and strong signal sensitivity. This makes Ti₃C₂Tₓ ideal for gas sensors, electrochemical biosensors, enzymatic detection platforms, and rapid-response analytical systems.
4. Electrocatalysis & Catalyst Supports
The combination of high conductivity and tunable surface chemistry allows the monolayer MXene to function as a high-performance electrocatalyst or as a support material for HER/OER, CO₂ reduction, and other electrochemical conversions.
5. NEMS, Films & Membranes
Single-layer MXene flakes can be assembled into ultrathin membranes, nanofilters, flexible films, and electrical components used in micro-/nanoelectromechanical systems where conductivity and mechanical flexibility are required.
6. Composite Materials & Hybrid Structures
When incorporated into polymers, hydrogels, or oxide matrices, Ti₃C₂Tₓ provides enhanced electrical pathways, thermal transport, mechanical reinforcement, and EMI attenuation, making it valuable for multifunctional films and engineered composites.
Production Overview
Ti₃C₂Tₓ MXene suspension is produced by selectively removing the aluminum (A-layer) from a Ti₃AlC₂ MAX phase using chemical etching. This process isolates layered Ti₃C₂Tₓ, which is then delaminated through intercalation and exfoliation to produce monolayer nanosheets. The resulting flakes are dispersed in water and stabilized to maintain their colloidal state and prevent restacking.
