SciMater™ MXene Dispersion (21 Series, Ti2C, Mo2C, Nb2C, V2C)-SCI Materials Hub

Product Overview

The 21-series MXene dispersions are based on few-layer or predominantly single-layer Ti₂C, Mo₂C, Nb₂C, and V₂C sheets. The liquid form reduces powder weighing and redispersion steps, making the products convenient for film formation, coating, slurry preparation, electrode processing, and composite experiments.

The basic 21-series structure may be represented as M₂X. Their surfaces commonly contain terminations such as —O, —OH, and —F, and the materials are frequently written as M₂CT_x in scientific literature. Actual lateral size, thickness, layer-number distribution, surface terminations, solvent composition, pH, and dispersion stability should be confirmed using batch-specific technical data.

Quick Selection Recommendations

Research Requirement	Recommended Model	Recommended Processing Route	Selection Rationale
Energy-storage electrodes, conductive films, coatings, and interface regulation	Ti₂C	Vacuum filtration, coating, slurry preparation, or composite mixing	Suitable for conductive-network formation and general-purpose thin-film or electrode research.
Catalysis, surface reactions, electrocatalytic coatings, and composite catalysts	Mo₂C	Drop casting, spray coating, catalyst loading, or electrode preparation	Recommended when Mo-based surface chemistry and catalytic interfaces are the primary focus.
Electrochemistry, photothermal films, coatings, and functional interfaces	Nb₂C	Spin coating, vacuum filtration, spray coating, or composite-film preparation	Suitable for film-based electrochemical, photothermal, and interface-sensitive studies.
Ion storage, sensing, catalytic films, and high-interface-area studies	V₂C	Electrode coating, thin-film deposition, sensing-layer preparation, or composite mixing	Recommended for V-based ion-storage and surface-sensitive functional research.

Final selection should also consider the batch-specific dispersion medium, pH, solids content, lateral size, layer-number distribution, surface terminations, oxidation state, substrate compatibility, and processing method.

Instructions for Use

01 Inspect the Dispersion Check color, sedimentation, leakage, and container integrity before use. Mild reversible sedimentation may be addressed by gentle mixing.
02 Mix Gently Use vortex mixing, slow stirring, or brief low-power ultrasonication. Avoid significant temperature rise and prolonged high-power treatment.
03 Adjust Concentration Dilute gradually with a compatible medium according to the experimental requirement, and record the final concentration and dilution ratio.
04 Prepare the Sample Use vacuum filtration, drop casting, spin coating, spray coating, blade coating, electrode-slurry preparation, or composite mixing as required.
05 Reseal and Store Reseal immediately after use, protect from light, and minimize air exposure.

Before reuse, inspect the dispersion for significant color change, irreversible agglomeration, abnormal precipitation, or loss of uniformity. Avoid prolonged exposure to elevated temperature, strong light, and repeated freeze–thaw cycles unless specifically supported by batch documentation.

Frequently Asked Questions

01Do all four dispersions have the same concentration?

Yes. Ti₂C, Mo₂C, Nb₂C, and V₂C few-layer / predominantly single-layer dispersions are listed at 5 mg/mL.

02Can the four chemical compositions be substituted directly for one another?

Direct substitution is not recommended. The metal composition affects electronic structure, surface chemistry, oxidation behavior, dispersion stability, and experimental performance. Selection should be based on the research objective and batch-specific technical data.

03Is mild sedimentation normal?

Mild sedimentation may occur in two-dimensional sheet dispersions during storage. Gently shake, stir, or briefly sonicate the container and confirm that the dispersion returns to a uniform state. Irreversible agglomeration or abnormal precipitation should be evaluated before use.

04Can the dispersions be used directly for film formation?

They may be used for vacuum filtration, drop casting, spin coating, spray coating, and blade coating. A small-scale process test is recommended because film quality depends on concentration, solvent, substrate, surface treatment, coating rate, and drying conditions.

05How should the dispersions be stored?

Store sealed and protected from light while minimizing air exposure. Avoid elevated temperature, strong light, and repeated freeze–thaw cycles. Low-temperature or inert-atmosphere storage may be considered for oxidation-sensitive experiments when supported by batch documentation.
