MIT Labs Moves Ahead In Synthesizing Spider Silk
icepick72 writes in with a link to an ExtremeTech article on new methods for creating synthetic spider silk. This material, like lycra in many ways, has a number of unique properties. The MIT lab that created it is being monitored by military elements, keenly interested in applications of this material to front-line technologies. From the article: "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 and mixing the molten plastics with reinforcing agents."
With great power comes great responsibility. Remember that, MIT. Remember that.
Ohhh... this stuff would make fabulous condoms. They could recover the entire R&D budget in three weekends.
Most of the stuff on
This work at MIT is not really an attempt to make synthetic spider silk but just something with similar properties.
Spider silk is a kind made of protein and the feedstock is a liquid crystal
A company called Spinox Ltd (an Oxford University Spin off -- get it? ha ha ). Here is a note from a Smith Insitute workshop on the topic.
This group is actually trying to emulate what goes on in a spider (biomimetics). The big advantage is that it uses harmless ingredients and low temperatures. Compare for example Kevlar, the manufacture of which needs concentrated sulfuric acid. Spinox details
