Spider Silk May Be Used To Build The Electronics Of The Future
Researchers found that the material conducts heat 800 times better than any other organic material, making it ideal for gadgets.
Xinwei Wang and his research team at Iowa State University have found that spider silk is an outstanding heat conductor, which could lead to new nature-based applications in technology and manufacturing. The stretchy and strong substance was found to conduct heat 800 times better than any other organic material.
Wang, an associate professor of mechanical engineering who studies thermal conductivity, ordered eight spiders known as golden silk orbweavers to find out whether their silk could effectively transfer heat. The team discovered that spider silk (particularly the draglines that anchor webs in place) conducts heat better than most materials, even very good conductors such as silicon, aluminum and pure iron. It conducts heat 1,000 times better than woven silkworm silk and 800 times better than other organic tissues. Wang said:
