Stronger silk fibre
found that adding graphene or carbon nanotubes to the food eaten by silkworms causes them to produce silk that is stronger than normal silk. They sprayed a water solution containing 0.2 per cent carbon nanotubes or graphene onto mulberry leaves and then fed the leaves to the silkworms. Tests conducted on the silk showed that it could withstand about 50 per cent more stress than traditional silk.
