American scientists have developed a type of nano membrane that is both durable and elastic. This membrane can be used to create disposable coffee cups or the outer shell of spacecraft.

Compressed carbon nano membrane |
The membrane is made from carbon nanotubes, functioning similarly to a spring layer in a mattress. It is elastic under applied force while maintaining its properties after thousands of compression cycles, unlike traditional spring mattresses.
Additionally, the nano membrane has a low density, making it an ideal material for creating ultra-lightweight structures akin to sponge.
According to Associate Professor Anyuan Cao from the University of Hawaii, the length of carbon nanotubes within the membrane can be compressed down to 15%, similar to a spring. After each compression cycle, the nanotubes rebound, creating an excellent shock-absorbing effect. The thickness of the tubes decreases slightly after several hundred compressions. After that, it stabilizes and remains unchanged throughout 10,000 compressions without any damage. The nanotubes are also highly stable when exposed to strong chemicals, high temperatures, and humidity.
Carbon nanotubes, made from carbon, were first created in 1991. Among other applications, nanotubes have been used to enhance concrete.
