The Synthetic Spider Silk Fact Nobody Knows | ScienceBlobs

[00:00:00]Did you know synthetic spider silk can reach tensile strengths up to 1.2 gigapascals?

[00:00:06]Which rivals the strongest steel on the planet.

[00:00:09]Did you know scientists replicate spider silk by engineering the protein spidroin?

[00:00:15]Which self-assembles like a natural spider silk gland at the molecular level.

[00:00:19]And that the entire process occurs under ambient room temperature with zero toxic solvents.

[00:00:25]Unlike conventional synthetic fibers.

[00:00:28]Unlike typical fibers, synthetic spider silk proteins fold during extrusion to form beta sheet nanocrystals that give it ultra-high strength and elasticity.

[00:00:38]Imagine a LEGO structure self-building itself perfectly while being stretched.

[00:00:43]Surprisingly, synthetic spider silk has a thermal conductivity similar to copper.

[00:00:48]Spider silk threads can conduct heat better than many metals.

[00:00:52]Think of a fiber as a tiny copper wire for heat transport.

[00:00:56]Synthetic spider silk displays a unique strain stiffening behavior.

[00:01:01]It stretches almost like chewing gum, but stiffens rapidly under increasing load.

[00:01:06]Like a stealthy ninja fiber that becomes stronger the harder you pull it.
