MIT’s progress in making synthetic spider silk

From this report [via slashdot]:

“If you look closely at the structure of spider silk, it is filled with a lot of very small crystals,” said Gareth McKinley, a professor of mechanical engineering and part of the group that devised the new method of producing the material.

“It’s highly reinforced.”

The secret of spider silk’s combined strength and flexibility, according to scientists, has to do with the arrangement of the nano-crystalline reinforcement of the silk as it is being produced—in other words, the way these tiny crystals are oriented towards (and adhere to) the stretchy protein.

Emulating this process in a synthetic polymer, the MIT team focused on reinforcing solutions of commercial rubbery substance known as polyurethane elastomer with nano-sized clay platelets instead of simply heating the mixing the molten plastics with reinforcing agents.
