Summary
Scientists at Cornell University have created the darkest fabric ever made, called "ultrablack." This fabric reflects less than 0.5% of light, making it unique because it stays very dark even when viewed from different angles. Researchers designed it by mimicking the structure of bird feathers, and it's easy to make from natural fibers.
Key Facts
- The ultrablack fabric reflects less than 0.5% of the light that hits it.
- Scientists took inspiration from the feathers of a bird called the 'magnificent riflebird.'
- The fabric is made using a process that includes dyeing with polydopamine and adding nanofibrils.
- It stays dark when viewed from angles up to 120 degrees.
- The fabric is easy to produce using natural materials like wool, cotton, and silk.
- It has potential uses in fashion, solar thermal applications, and camouflage.
- The team has applied for provisional patent protection for the fabric.
- A fashion student used the fabric to make a dress as a design centerpiece.
