What Is Vantablack Made Of? The Definitive Answer
Vantablack is made of vertically aligned carbon nanotubes-an ultra-dense "forest" of pure carbon tubes grown on a substrate, typically aluminum foil. Each nanotube measures roughly 20 nanometers in diameter (about 3,500 times thinner than human hair) and 14-50 micrometers in length, with approximately one billion nanotubes packed into just 1 cm² of surface area. This structure absorbs 99.965% of visible light, making it the darkest man-made material ever recorded.
The Core Composition: Carbon Nanotubes in Perfect Alignment
The pure carbon nanotubes that form Vantablack are not painted on but chemically grown through a patented chemical vapor deposition (CVD) process at Surrey NanoSystems in Newhaven, England. This process began in 2012 and culminated in the public unveiling at Farnborough Airshow in July 2014. Unlike traditional pigments that absorb light through chemical composition, Vantablack traps light physically: photons enter the nanotube forest, bounce between tubes, and are converted into harmless heat energy with almost zero reflection.
Key structural facts about the carbon nanotube forest:
- Diameter per nanotube: ~20 nanometers (3,500x thinner than human hair)
- Length per nanotube: 14-50 micrometers
- Density: ~1 billion nanotubes per cm²
- Material purity: >99.9% pure carbon
- Empty space: >99% of the material's volume is void
How Vantablack Is Manufactured: A Patented Two-Day Process
The patented growth process requires extreme precision, controlled heat, and multiple deposition layers. Surrey NanoSystems' CTO, Ben Jensen, confirmed in a 2017 Wired interview that light entering the nanotubes is absorbed and transformed into heat, which then dissipates safely. The entire manufacturing cycle takes up to 48 hours per batch.
- Substrate preparation: Ultra-clean aluminum foil is placed in a vacuum chamber
- Catalyst layer application: A thin iron or cobalt catalyst is deposited to seed nanotube growth
- Carbon feedstock injection: Hydrocarbon gas (typically ethylene or methane) is introduced
- Controlled heating: The chamber reaches 600-700°C to activate CVD reaction
- Nanotube growth: Carbon atoms assemble into vertically aligned tubes over 12-24 hours
- Post-processing: Optional protective coating or spray formulation for commercial versions
Physical and Optical Properties Table
The following table summarizes Vantablack's verified optical and physical characteristics, measured by the UK's National Physical Laboratory in Teddington:
| Property | Value | Measurement Wavelength |
|---|---|---|
| Light absorption | 99.965% | 750 nm (near-infrared) |
| Light reflection | 0.035% | 700 nm (red visible) |
| UV absorption range | 200-350 nm | Ultraviolet spectrum |
| Visible absorption range | 350-700 nm | Full visible spectrum |
| Infrared absorption | >16 microns | Far-infrared spectrum |
| Hydrophobicity | Extremely high | Water beads and rolls off |
| Cost per ounce | >$10,000 | More expensive than gold/diamonds |
Applications Across Industries
Vantablack was originally engineered for defense and space applications, specifically to coat telescope apertures and satellite optical sensors to eliminate stray light from the sun and moon. Today, it's used in aerospace, high-end optics, automotive sensing, and even art. Artist Anish Kapoor secured exclusive artistic rights in 2016, sparking controversy in the creative community.
Major application sectors include:
- Astronomical telescopes and space instrumentation
- Infrared and electro-optical imaging systems
- 光学 baffles and aperture coatings
- Luxury watches, automotive trim, and deodorant cans (consumer prototypes)
- Visual art installations (e.g., Diemut Strebe's 3D-printed Vantablack sculpture)
Historical Context and Record-Breaking Status
Before Vantablack, NASA held the record with a carbon nanotube-based "super-black" coating developed in 2007. However, Surrey NanoSystems achieved lower reflection through lower-temperature CVD processing, enabling application on temperature-sensitive materials like aluminum. In 2015, Guinness World Records officially recognized Vantablack as the "World's Darkest Man-Made Substance".
"Light enters as photons, interacts with the nanotubes, and is absorbed, transformed into heat, which then dissipates."

Future Variants and Next-Gen Ultra-Black Materials
Since 2014, Surrey NanoSystems has released improved versions including Vantablack S-VIS (sprayable) and VBx2 (enhanced durability). In 2019, MIT researchers created an even darker material using vertical carbon nanotubes on aluminum that absorbs 99.995% of light, though it remains experimental and not commercially available.
Key upcoming developments:
- Spray-on versions for automotive and consumer goods
- Flexible coatings for wearable sensors
- Next-gen materials absorbing >99.99% of light (MIT prototype)
Final Takeaway: Pure Carbon, Perfect Darkness
Vantablack's identity is simple yet revolutionary: it is made of pure carbon nanotubes arranged in a vertically aligned array that traps nearly all incident light. This achievement combines materials science, nanotechnology, and physics to create a material that functionally erases visual depth. From satellite telescopes to controversial art pieces, Vantablack remains the benchmark for ultra-black materials in 2026.
What are the most common questions about Vantablack Recipe Blows Minds Wide Open?
What is Vantablack made of exactly?
Vantablack is made of vertically aligned carbon nanotubes-pure carbon structures grown in a dense forest-like array on aluminum foil. Each tube is ~20 nm wide and 14-50 μm long, with one billion tubes per cm².
Is Vantablack a paint or pigment?
No, Vantablack is not a paint, pigment, or fabric. It is a functionalized nanotube array grown directly onto surfaces through chemical vapor deposition. A sprayable consumer version (Vantablack S-VIS) exists but still relies on the same carbon nanotube chemistry.
How dark is Vantablack compared to ordinary black?
Vantablack absorbs 99.965% of visible light, reflecting only 0.035%. Ordinary black paint reflects 5-10%, while NASA's super-black reflects ~0.5%. This makes Vantablack roughly 10x darker than previous records.
Can you touch or scratch Vantablack?
The original CVD version is extremely delicate and cannot be touched without damaging the fragile nanotube forest. The sprayable S-VIS version is more durable and can be brushed or handled, though it still reflects slightly more light (~1%).
Who invented Vantablack and when?
Vantablack was invented by Surrey NanoSystems, a British nanotechnology company based in Newhaven, England. Development began in 2012, and it was publicly announced at the Farnborough Airshow in July 2014.
Why is Vantablack so expensive?
Vantablack costs over $10,000 per ounce-more than gold or diamonds-due to its complex two-day growth process, vacuum chamber requirements, and extreme precision needed to align billions of nanotubes per square centimeter.
