Won Jun Song at Seoul National University in South Korea and his colleagues based the silk in their spider webs on a composite of silicone, a highly conductive gel and a hydrophobic coating.
What are spider webs made of?
Spiders make their webs from silk, a natural fibre made of protein. Not only does spider silk combine the useful properties of high tensile strength and extensibility, it can be beautiful in its own right. Jan says, ‘Silk is an amazing material.
Can humans make spider silk?
Humans have been making use of spider silk for thousands of years. The ancient Greeks used cobwebs to stop wounds from bleeding and the Aborigines used silk as fishing lines for small fish.

Can spider silk be spun?
Spider silk is made of proteins that are stored as an aqueous solution in the silk glands, before being spun into a fiber. “This is the first successful example of biomimetic spider silk spinning. We have designed a process that recapitulates many of the complex molecular mechanisms of native silk spinning.

Essentially, that means a strand of silk is much stronger for its size than a steel beam is.
