London, Sep 4 (PTI) Scientists have found a way to make spiders spin stronger silks using carbon nanotubes or graphene, paving the way for high-strength materials that could be used to make improved parachutes and body armours.
Researchers, led by Professor Nicola Pugno at the University of Trento in Italy, succeeded in having their spiders produce silk with up to three times the strength and ten times the toughness of the regular material.
The discovery, published in the journal 2D Materials, could pave the way for a new class of bionicomposites, with a wide variety of uses.
“Humans have used silkworm silks widely for thousands of years, but recently research has focussed on spider silk, as it has extremely promising mechanical properties,” said Pugno.
“It is among the best spun polymer fibres in terms of tensile strength, ultimate strain, and especially toughness, even when compared to synthetic fibres such as Kevlar,” he said.
