The TCI Carbon Nanotube Multi-walled, catalogue code C2155, is a nanocarbon material in the form of multi-walled tubes with a diameter of 20–40 nm and a length of 1–2 micrometres. The material consists of graphene sheets rolled concentrically to form a hollow cylindrical structure with a very high length-to-diameter ratio. In the laboratory, it serves as a functional filler for composite materials, as an active material or conductivity-supporting component in electrodes, and as a subject of study in fundamental research on the properties of nanoscale materials.
The characteristics that make this variant a frequent choice are the combination of a relatively small diameter with a short length. A diameter of 20–40 nm provides a larger specific surface area than thicker-diameter tubes, so interfacial interaction with polymer matrices, resins, or electrolyte solutions becomes more intensive. A length of 1–2 micrometres makes the tubes comparatively easier to disperse and less prone to forming mutually entangled agglomerates, so that sonication as well as mechanical mixing can produce a more uniform suspension.
In Indonesian laboratories, this material is typically used in materials science and nanotechnology research groups working on composites, electrode preparation, and fundamental studies of nanoscale material behaviour. It is commonly handled during the preparation of filler-loaded formulations, during dispersion work involving sonication or mechanical mixing, and during the assembly of electrode systems where conductivity support is required. Its role sits at the sample-preparation and characterisation stage rather than in routine analytical testing.
- Composite material reinforcement — the tubes act as a functional filler, and the 20–40 nm diameter gives an interface with polymer or resin matrices that is more intensive than thicker tubes provide.
- Electrode fabrication — the material serves as an active or conductivity-supporting component, with the high length-to-diameter ratio of the hollow cylindrical structure assisting conductive pathways within the electrode body.
- Dispersion and suspension preparation — the short 1–2 micrometre length reduces the tendency to form entangled agglomerates, so sonication or mechanical mixing yields a more uniform suspension.
- Electrolyte interface studies — the larger specific surface area associated with the 20–40 nm diameter intensifies interaction with electrolyte solutions, making the material suitable for interfacial investigation work.
- Fundamental nanoscale materials research — the defined multi-walled structure and stated dimensional range make this variant a usable reference object for studying properties of materials at the nanometre scale.

Store the container tightly closed in a dry location, protected from moisture and away from sources of ignition, and keep it in the original manufacturer's packaging or an equivalent clean, sealed container that prevents contamination and material escape. Because the material is a fine nanoscale powder that disperses easily into the air, handle and weigh it inside a fume hood or an enclosed workspace, and use gloves, safety glasses, and a laboratory coat together with appropriate respiratory protection. Avoid raising dust during transfer, weighing, and sonication steps. Clean work surfaces and equipment after use, and follow the manufacturer's safety data sheet along with your institution's procedures for nanomaterial handling and waste disposal.
