According to Wikipedia: "The bulk modulus of superhard phase nanotubes is 462 to 546 GPa, even higher than that of diamond (420 GPa for single diamond crystal)." Note that diamonds are natural minerals; nanotubes are fabricated, making diamond the hardest known natural substance. You can read more about nanotubes, below.
Since the nanotubes are very small, only some molecules can fit through them. Water is able to pass through, but the impurities in water like bacteria, metals, and viruses will not fit through. Therefore, the water will be purified through nanotubes.
They are put in paint to strengthen vehicles or sometimes used in nanometer sized electronics.
Because nobody wants an unpure carbon nanotube
the structure of nanotubes are carbon atoms joint together covalently to form a long tube.

Strength:Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively.Hardness:Standard single-walled carbon nanotubes can withstand a pressure up to 25 GPa without deformation.

Although there are numerous instances of people observing carbon nanotubes, most literature credits Sumio Iijima as the discoverer of carbon nanotubes.

It depends on the structure.

This technology is being explored as an option for body armor, but there are no body armor products using carbon nanotubes as yet.
