China's New Blackest Black Paint Absorbs 99.9% Of Light, Rivaling BMW's 99.965%
Chinese researchers develop a light-absorbing paint that rivals BMW's Vantablack, absorbing 99.9% of light.
Key Takeaways
- Chinese researchers created a paint that absorbs 99.90 percent of light.
- The paint combines nanoscale carbon black and carbon nanotubes.
- Panels survived 10 days underwater and 104 degrees without damage.
- The paint’s formula is a derivative of Vantablack, but more suitable for car manufacturers.
- The paint’s durability and resistance to UV, scratches, and corrosion are still unknown.
What Makes the Chinese Paint Different?
In my experience, the development of a new paint that rivals Vantablack is a significant achievement. The Chinese researchers’ formula combines nanoscale carbon black and carbon nanotubes, sourced from outside suppliers, to create a finish that absorbs more than 99.90 percent of light.
This is a notable improvement over BMW’s Vantablack, which absorbs 99.965 percent of light. The Chinese paint’s ability to withstand humidity levels of up to 95 percent at 40 °C or 104 °F is also impressive.
How Does the Paint Work?
The paint’s unique formula creates an irregular surface studded with microscopic peaks and valleys that absorb light. When light touches the surface, it bounces around these valleys, rather than reflecting out.
This is achieved by mixing carbon black and carbon nanotubes with a mixture of deionized water, dispersant, and deformer. The result is a finish that is not only incredibly dark but also remarkably durable.
What Are the Potential Applications?
While the paint’s durability and resistance to UV, scratches, and corrosion are still unknown, its potential applications are vast. If commercialized, it could be used in various industries, including automotive, aerospace, and even art.
However, it’s essential to note that the study was primarily focused on testing the paint’s adhesive properties and figuring out whether it could survive on a car at all.
Comparison to Vantablack
| Paint | Light Absorption | Durability |
|---|---|---|
| Vantablack | 99.965% | Fragile, not suitable for car manufacturers |
| Chinese Paint | 99.90% | Durable, withstood 10 days underwater and 104 degrees without damage |
Conclusion
In conclusion, the Chinese researchers’ development of a light-absorbing paint that rivals Vantablack is a significant achievement. While its potential applications are vast, further testing is needed to determine its durability and resistance to various environmental factors.
Frequently Asked Questions
