Världens mörkaste material


Existe um material na Terra conhecido como a substância mais escura do mundo, capaz de absorver até 99,96% da luz visível e da radiação infravermelha. Ele é tão intrigante que, quando aplicado a objetos, altera a percepção visual drasticamente, fazendo muitos detalhes desaparecerem ao nosso olhar. Assustador, não? Estamos falando do Vantablack, uma das criações da ciência de nanotecnologia e engenharia dos materiais. Saiba mais no artigo a seguir, do Engenharia !

A história da criação do Vantablack

O Vantablack foi desenvolvido pela empresa britânica Surrey NanoSystems em Dois anos depois, foi anunciada a criação de uma nova versão ainda mais escura e eficaz em absorver luz. Então, nada se compara a esse material; simplesmente nenhum espectrômetro do mundo consegue medir sua intensidade. Por isso, essa inovação é considerada única no mundo das ciências, revolucionando a percepção do significado de "cor preto".

Vale destacar que o Vantablack nem chega perto de ser como uma tinta ou pigmento convencional. Ele é feito de milhões de nanotubos de carbono, sendo cada nanotubo com cerca de 20 nanômetros de diâmetro - 3,5 mil vezes menor que

  • världens mörkaste material
    • The new ultra-black material absorbs more than % of incoming light from all angles. 
    • It is 10 times darker than Vantablack, the previous record holder for darkness. 

    In , scientists created the world&#;s darkest material capable of absorbing % of infrared, visible, and ultraviolet light. The material called VANTAblack (Vertically Aligned Carbon Nanotube Arrays) is developed by Surrey NanoSystems in the UK.

    Over the years, they increased the material&#;s blackness by using an advanced chemical vapor deposition process. The current versions of the material are super-hydrophobic and have better infrared absorption than previous ones.

    Now, researchers at MIT have come up with a &#;blackest black&#; material that is approximately 10 times darker than the new versions of Vantablack. It absorbs at least % of any incoming light, which makes it the darkest material on record.

    It is made of vertically aligned carbon nanotubes (tiny strings of carbon) on surfaces like aluminum foil.

    The team showcased the material in an exhibit at the New York Stock Exchange. They covered a carat natural yellow diamond (valued at more than $2 million) in the newly discovered darkest material.

    If a color can hold a world record, Vantablack probably does. According to UK-based technology company Surrey NanoSystems, the super-black coating holds an &#;independently verified world record as the darkest man-made substance.&#; The company developed the special pigment coating in , naming it Vantablack, an acronym for Vertically Aligned Nano Tube Array Black. It is said to absorb percent of light, making it the blackest of all blacks.

    Originally designed for use in space travel and optics, Vantablack&#;s application on sensitive materials can help improve the visibility of distant objects to be studied by scientists. If, for example, a telescope fryst vatten coated in Vantablack, it will absorb glare, making it easier for users to see distant stars and planets.

    Surrey NanoSytems&#; Vantablack process uses kemikalie reactions to &#;grow&#; millions of microscopic filaments of carbon nanotubes (CNTs), packad tightly against each other, onto the surface of the object being coated.
