Crean material mA?s liviano del mundo

Fuente: Noticias 24

En la Universidad de Zhejiang, en China, investigadores han desarrollado una espuma que emplea nanotubos de carbono congelados en seco y lA?minas de A?xido de grafeno. Gracias a esta combinaciA?n, el llamado ai???Ultra-light Aerogelai??? se convierte en el material mA?s ligero a nivel mundial.

Con esta creaciA?n, los investigadores rompen el rAi??cord del material mA?s ligero, con una flexibilidad y absorciA?n de aceite sorprendentes. El aerogel es la sustancia mA?s ligera registrada en el libro de Guinness. Este resultado es un material con una densidad de 0,16 miligramos por centAi??metro cA?bico. Para ejemplificar su ligereza, el ai???Ultra-light Aerogelai??? puede ser colocado sobre una flor de cerezo y sin daAi??arla.

Para romper el rAi??cord anteriormente registrado, el profesor Gao Chao, junto a su equipo, desarrollA? un material tridimensional poroso de grafeno. ai???Es como las grandes estructuras espaciales o estadios, con barras de acero como soporte y la pelAi??cula de alta resistencia como las paredes para lograr tanto la ligereza como la fuerza. AquAi??, los nanotubos de carbono son los apoyos y el grafeno es el muroai???, asegurA? el cientAi??fico.Ai??
