TCI C2154 Carbon Nanotube Multi-walled, with a diameter of 20–40 nm and a length of 5–15 micrometres, is a nanocarbon material consisting of tube-shaped structures built from concentrically rolled graphene sheets. Compared with smaller-diameter variants, these medium-diameter tubes are generally easier to disperse, because the attractive forces between individual tubes tend to be weaker than in very slender nanotubes. In the laboratory, the material serves as a conductive filler, a catalyst support, an electrode component, and a subject of materials characterisation studies across a broad range of materials science and nanotechnology engineering work.
The property that matters most when selecting this particular variant is the balance it strikes between aspect ratio and ease of processing. At a length of 5–15 micrometres, the tubes remain long enough to form interconnected conductive networks within a matrix, while the 20–40 nm diameter confers greater bending stiffness, so the tubes are less prone to entangling into tightly packed agglomerates. The multi-walled structure provides good mechanical strength and thermal stability, and the carbon surface can still be chemically functionalised, allowing the material to be adapted to different formulations and experimental requirements.
In Indonesian laboratories, this grade of multi-walled carbon nanotube is typically used in university research groups, materials engineering departments, and institutional research centres. It supports work on conductive composites, energy storage electrodes, supported catalysts, and nanostructure characterisation, where the combination of a workable aspect ratio and manageable dispersion behaviour makes experimental preparation more straightforward. It is also well suited to method development and to teaching laboratories that introduce students to the handling and analysis of nanocarbon materials.
- Conductive filler in polymer composites: the 5–15 micrometre length allows tubes to bridge across the matrix and form percolating conductive networks at workable loadings.
- Catalyst support preparation: the multi-walled carbon surface offers a stable, functionalisable substrate on which active phases can be deposited and studied under laboratory conditions.
- Electrode component fabrication: the combination of electrical conductivity, mechanical strength and thermal stability suits research on energy storage and electrochemical electrode formulations.
- Materials characterisation studies: the defined 20–40 nm diameter and multi-walled morphology make this grade a suitable reference object for microscopy, spectroscopy and structural analysis work.
- Dispersion and formulation development: the medium diameter reduces inter-tube attraction and bending flexibility, so this variant is convenient for developing and comparing dispersion protocols.

Store the product in its original, tightly closed container in a dry, well-ventilated area away from moisture, ignition sources and incompatible chemicals. Because the material is a fine nanocarbon powder, it is easily made airborne, so all weighing and transfer operations should be carried out in a fume hood or an enclosed handling station. Laboratory personnel should wear a lab coat, gloves, safety goggles and appropriate respiratory protection, and should avoid generating dust when opening or dispensing the container. Keep the container closed when not in use, clean any spills with wet or vacuum methods rather than dry sweeping, and dispose of residues and contaminated consumables in accordance with the applicable laboratory waste procedures. Always consult the manufacturer's safety data sheet before use.
