Vantablack. The name itself evokes images of infinite darkness, a void so deep it seems to swallow light itself. Developed by Surrey NanoSystems, this revolutionary material has captured the imagination of artists, scientists, and tech enthusiasts alike. But beyond its captivating appearance lies a fundamental question: how expensive is it to get your hands on Vantablack? The answer, as you might expect, is complex and depends on several factors.
Understanding Vantablack: More Than Just a Color
Before diving into the price, it’s crucial to understand what Vantablack actually is. It’s not a pigment or a paint in the traditional sense. Instead, it’s a coating made up of billions of microscopic carbon nanotubes, each one about 20 nanometers wide. These nanotubes stand on end, creating a forest-like structure that traps almost all incoming light.
When light hits Vantablack, it enters the spaces between the nanotubes and is effectively absorbed, bouncing around until it’s converted into heat. This process gives Vantablack its extraordinary light-absorbing properties, making it appear incredibly black. Different versions of Vantablack exist, affecting cost and application.
Vantablack S-VIS: The Original and Most Expensive
The original Vantablack, known as Vantablack S-VIS, is the most demanding to produce and, consequently, the most expensive. This is because it requires a high-temperature environment and specialized equipment to grow the carbon nanotubes. The process, called Chemical Vapor Deposition (CVD), is meticulously controlled to ensure the uniform growth of the nanotubes. This sophisticated process significantly impacts the cost.
Vantablack VBx: A More Accessible Alternative
Recognizing the limitations of Vantablack S-VIS, Surrey NanoSystems developed Vantablack VBx, a sprayable version of the material. While it doesn’t achieve the same level of light absorption as S-VIS (it absorbs around 99% of light, compared to S-VIS’s 99.965%), VBx is significantly easier and cheaper to apply. This makes it a more accessible option for a wider range of applications.
The Factors That Influence Vantablack’s Price

What makes Vantablack so expensive?
Vantablack’s extreme price stems from its complex manufacturing process and unique properties. It’s not a pigment or paint in the traditional sense, but rather a coating of vertically aligned carbon nanotubes (VACNTs). Creating this structure requires specialized equipment, precise environmental controls, and a delicate fabrication process in a laboratory setting. The material’s ability to absorb 99.965% of light across the visible spectrum is due to this intricate nanotube arrangement, making it extremely difficult and costly to produce reliably.
Furthermore, the scarcity of Vantablack contributes significantly to its high cost. Surrey NanoSystems, the original developer, has limited its availability for various reasons, including concerns about its potential misuse in military applications. This controlled access, combined with the technological challenges of production, results in a premium price point, making it inaccessible for most everyday applications.
How does the cost of Vantablack compare to other black materials?
Compared to standard black paints and coatings, Vantablack is significantly more expensive, orders of magnitude so. Common black pigments like carbon black are readily available and relatively inexpensive to produce. Even specialized black paints with advanced formulations do not come close to the cost of Vantablack, as they lack the unique nanoscale structure and light-absorbing capabilities of VACNTs.
While some alternative super-black materials have emerged in recent years aiming to rival Vantablack’s light absorption, these alternatives still tend to be substantially more expensive than typical black paints. The key factor is that the fabrication of materials with very high light absorption properties often necessitates sophisticated technologies and highly controlled environments that drive up the costs.
What is the estimated cost per square meter of Vantablack?
Estimating the exact cost per square meter of Vantablack is difficult due to the lack of publicly available pricing information. Surrey NanoSystems typically handles requests on a case-by-case basis, taking into account the specific application, quantity required, and technical specifications.

Surrey NanoSystems carefully controlled its distribution, prioritizing projects where the unique properties of the material would provide significant advantages. However, more recently, the company has offered variations of Vantablack with slightly different properties and application methods, broadening its accessibility to certain artistic and commercial projects.
Even with increased availability, access to Vantablack remains restricted. The company typically evaluates potential clients and projects to ensure responsible use of the material. Factors considered include the intended application, the scale of the project, and the potential for misuse. This controlled distribution model ensures the material is used ethically and appropriately.
Are there any cheaper alternatives to Vantablack?
While no material perfectly replicates Vantablack’s light-absorbing capabilities at a significantly lower price, several alternative super-black coatings offer comparable performance for specific applications. These alternatives often employ different technologies, such as sprayable black coatings with specialized pigments and microstructures designed to trap light. These can achieve high levels of blackness but fall short of Vantablack’s record.
Furthermore, research is ongoing to develop more affordable and scalable super-black materials. Scientists are exploring new fabrication techniques and material compositions to reduce production costs. While these alternatives may not be as “black” as Vantablack, they can provide a cost-effective solution for applications where extreme light absorption is not strictly required.
What are some applications where Vantablack’s cost is justified?
In some specialized applications, the unique properties of Vantablack justify its considerable cost. For example, in space telescopes and satellite components, its ability to absorb stray light and reduce glare can significantly improve image quality and sensor performance. Similarly, in high-precision scientific instruments, Vantablack can minimize reflections and enhance the accuracy of measurements.
Vantablack also finds uses in certain military applications, such as camouflage and stealth technology, where its ability to absorb radar signals and reduce visibility is highly valuable. While these are niche cases, the enhanced performance in these situations is critical and justifies the high expense. The key is when superior light absorption has a quantifiable impact.
What factors affect the final cost of a Vantablack application?
Several factors contribute to the final cost of a Vantablack application beyond the raw material price. The size and complexity of the object being coated, the surface preparation required, and the application method all play a significant role. Applying Vantablack typically involves specialized equipment and trained technicians, further increasing expenses.
Furthermore, any custom modifications or specific performance requirements can add to the cost. If the application requires a particularly durable or heat-resistant coating, for instance, the development and application process may become more complex and expensive. Therefore, the total investment needs to factor in both the cost of the materials, the specialized labor, and the added requirements of the client.
