Watch the incredible self-healing fabric that can repair rips in clothes

Daily Mail - Science & tech

Clothing of the future could have the ability to repair itself after a tear – all you need to do is add water. Researchers have developed a coating for textiles that can heal itself, and neutralize harmful chemicals. They say this could one day be used to make chemically protective suits, helping to keep everyone from soldiers to farmers safe from toxic materials. Clothing of the future could have the ability to repair itself after a tear – all you need to do is add water. Polyelectrolytes coating is composed of positively and negatively charged polymers.


No More Ripped Jeans: Squid Tooth Protein Could Lead to Self-Repairing Clothes

International Business Times

The future of mending clothes may require one less tailor and one extra squid. In a new development, researchers at Pennsylvania State University have discovered healing properties in the proteins from squid ring teeth that can self-repair some fabrics. According to the team, this technology can be applied to create chemically protective suits that protect farmers from pesticide exposure, factory workers from toxic ingredients and soldiers from chemical and biological attacks. "Fashion designers use natural fibers made of proteins like wool or silk that are expensive and they are not self-healing," said Melik C. Demirel, professor of engineering science and mechanics at Penn State, in a statement. "We were looking for a way to make fabrics self-healing using conventional textiles.


Soft robotics actuators heal themselves

Repeated activity wears on soft robotic actuators, but these machines' moving parts need to be reliable and easily fixed. Now a team of researchers has a biosynthetic polymer, patterned after squid ring teeth, that is self-healing and biodegradable, creating a material not only good for actuators, but also for hazmat suits and other applications where tiny holes could cause a danger. "Current self-healing materials have shortcomings that limit their practical application, such as low healing strength and long healing times (hours)," the researchers report in today's (July 27) issue of Nature Materials. The researchers produced high-strength synthetic proteins that mimic those found in nature. Like the creatures they are patterned on, the proteins can self-heal both minute and visible damage.

"Our goal is to create self-healing programmable materials with unprecedented control over their physical properties using synthetic biology," said Melik Demirel, professor of engineering science and mechanics and holder of the Lloyd and Dorothy Foehr Huck Chair in Biomimetic Materials. Robotic machines from industrial robotic arms and prosthetic legs have joints that move and require a soft material that will accommodate this movement.


Navy backs 'omniphobic' coatings to help ships travel further

Researchers have already explored the idea of using water-repellent ship coatings that let ships travel faster and further. The US Navy, however, is taking things a step further. It's backing University of Michigan work on an "omniphobic" coating that shrugs off virtually any liquid (it'll even fend off peanut butter) while lasting for a long time. Ships could theoretically glide through the water without nearly as much friction as ordinary vessels, consuming less fuel and traveling longer. The scientists purposefully bucked conventional wisdom, which would combine the most repellent filler material with an equally durable polymer matrix.
