TCI C2157 is a multi-walled carbon nanotube material with a diameter of 40–60 nm and a length of 1–2 micrometers. This nanocarbon material consists of hollow tubes built from several concentric graphene wall layers, with a comparatively short tube length relative to other variants in the same series. In the laboratory, it is used as a functional filler in composites, as a conductivity enhancer in electrode formulations, as a carbon-based catalyst support, and as a test material in dispersion studies and nanoscale material characterization work.
The main characteristic that makes this variant attractive is the balance between a medium diameter and a short tube length. Short tubes tend not to form heavily entangled bundles that are difficult to separate, so dispersion using a sonicator or a high-speed mixer proceeds more quickly and produces a suspension that is more homogeneous and more stable. The 40–60 nm diameter makes the powder easier to handle, less prone to becoming airborne, and still provides sufficient surface area for interfacial interaction. The multiple walls contribute mechanical strength, electrical conductivity, and structural stability.
In Indonesian laboratories, this material is typically found in materials science, chemistry, and engineering research groups working on polymer composites, energy storage, and catalysis. It is commonly used in university research facilities and institutional laboratories where reproducible dispersion behavior matters, since the shorter tube length reduces the processing time needed before a sample is ready for coating, casting, or electrochemical testing.
- Polymer composite reinforcement — the multi-walled structure provides mechanical strength while the short tube length allows more uniform distribution throughout the polymer matrix during compounding.
- Conductive electrode formulation — the electrical conductivity of the concentric graphene walls supports charge transport in electrode films prepared for energy storage research.
- Carbon-based catalyst support — the hollow tubular morphology and available surface area allow catalytic species to be anchored across an accessible carbon framework.
- Dispersion and suspension studies — short tubes disentangle more readily under sonication, giving researchers homogeneous and stable suspensions for reproducible experimental work.
- Nanoscale material characterization — the defined 40–60 nm diameter and 1–2 micrometer length make this a suitable reference sample for morphology and structure analysis.

Store the material in a tightly closed original container in a dry, well-ventilated area, away from moisture and sources of ignition. Glass or chemically resistant plastic containers with secure closures are suitable for storage and for aliquoting smaller working quantities. Because the material is a fine nanocarbon powder, all weighing and transfer operations should be carried out in a fume hood or a suitable containment enclosure to limit airborne dispersal. Laboratory personnel should wear gloves, safety glasses, a laboratory coat, and appropriate respiratory protection when handling the dry powder. Clean spills using wet wiping or vacuum methods rather than dry sweeping, keep the container closed when not in use, and consult the manufacturer's safety data sheet before beginning work.
