Natural spider silk has excellent mechanical properties. Researchers from the Graphene Flagship have found a way to boost the strength of spider’s silk using graphene-based materials, paving the way for a novel class of high-performance bionic composite.
Researchers from the Graphene Flagship have demonstrated that graphene-based materials can be used to boost the properties of spider’s silk. The silk — produced naturally by the spiders, incorporating graphene and carbon nanotubes (rolled up graphene sheets) introduced in their environment – had enhanced mechanical properties of up to 3X the strength and 10X the toughness of the unmodified silks.
Artificially modified biological materials are an expanding area of...
