Single-Walled Carbon Nanotubes: The High-Conductivity Nanomaterial, Now Manufactured in Indonesia

Single-walled carbon nanotubes (SWCNTs) are the original carbon nanotube: a single sheet of graphene rolled into a seamless cylinder just one atom thick. That single-layer structure is what gives SWCNTs their standout properties, higher electrical conductivity, larger specific surface area, and unique optoelectronic behavior that multiwalled carbon nanotubes can't fully match, making SWCNTs the material of choice wherever performance matters more than cost.

Research labs in Indonesia have typically had to import SWCNTs with genuinely verified conductivity and electrochemical performance. That's starting to change.

ITNANO (CV. Inovasi Teknologi Nano), based at the NRE Lab in Medan, is Indonesia's first private nanomaterials research startup manufacturing SWCNTs locally, with electrochemical testing run directly on every batch. Here's what SWCNTs actually are, why their single-wall structure matters, and where they're being used in research and industry today.

What Are SWCNTs?

SWCNTs are formed from a single graphene sheet rolled into a cylinder, unlike multiwalled carbon nanotubes, which nest several of these cylinders inside one another. That single-layer structure gives every carbon atom in an SWCNT direct exposure to its surroundings, which is what drives their larger specific surface area and stronger electronic response compared to multiwalled tubes. ITNANO's SWCNTs are supplied in research-grade black powder form, with an electrical conductivity of 2,000-2,900 S/m and a moisture content of 2.5%.

Every batch is electrochemically tested by coating the SWCNTs onto Ni foam and running it through a three-electrode system in 1 M KOH electrolyte, recording a specific capacitance of 719.60 F/g at 1 A/g, a result that confirms ITNANO's SWCNTs are suitable for supercapacitor and battery applications.

Where SWCNTs Are Being Used

Battery and supercapacitor electrodes

The 719.60 F/g specific capacitance recorded on ITNANO's SWCNTs shows this material is well suited as an electrode material for batteries and supercapacitors, where its high conductivity supports efficient charge transport during charge and discharge cycles.

High-performance composites and conductive coatings

SWCNTs are also used in high-performance composite materials, conductive materials, and coatings, where their combination of strength and conductivity outperforms what's achievable with bulkier conductive fillers.

Sensors, nanoelectronics, and transparent conductive films

SWCNTs' unique optoelectronic properties make them a key material for sensors, nanoelectronic devices, and transparent conductive films, applications where multiwalled tubes' bulkier structure is less suited.

Biomedical applications and solar cells

Beyond energy and electronics, SWCNTs are researched for use in biomedical applications and solar cells, extending their reach across some of the most demanding areas of materials research.

Why Source SWCNTs Locally

Electrical conductivity and electrochemical performance in SWCNTs are properties sensitive to synthesis conditions, and a batch with inconsistent conductivity or higher moisture content will underperform even though its basic chemical composition stays the same. ITNANO, established by the Titian Research Group's NRE Lab, manufactures SWCNTs domestically with direct electrochemical testing on every batch, giving labs in Indonesia a material whose performance is genuinely verified.

Whether you're developing battery or supercapacitor electrodes, formulating high-performance composites, building sensors and nanoelectronic devices, or researching biomedical applications, SWCNTs give you a conductivity and performance consistency that a distant supplier can't guarantee after shipping, without the import wait.
