[ Watch the Video: Regenerating Plastic Grows Back After Damage ] redOrbit Staff & Wire Reports - Your Universe Online Taking inspiration from the way in which blood clots can help repair wounds, engineers from the University of Illinois have developed a new regenerating plastic capable of regrowing material to fill in cracks and holes. According to BBC News reporter James Morgan, previous research in the field of self-healing materials could only focus on microscopic cracks....

Internal damage in fiber-reinforced composites, materials used in structures of modern airplanes and automobiles, is difficult to detect and nearly impossible to repair by conventional methods. A small, internal crack can quickly develop into irreversible damage from delamination, a process in which the layers separate. This remains one of the most significant factors limiting more widespread use of composite materials. However, fiber-composite materials can now heal autonomously through a...

Researchers of KIT and Evonik Industries Have Developed a Novel Polymer Network that Selfheals Rapidly and Repeatedly at Relatively Low Temperatures Scratches in the car finish or cracks in polymer material: Self-healing materials can repair themselves by restoring their initial molecular structure after the damage. Scientists of the Karlsruhe Institute of Technology and Evonik Industries have developed a chemical crosslinking reaction that ensures good short-term healing properties of...

Self-Healing Polymers From Off-The-Shelf Materials

University of Illinois at Urbana-Champaign Look out, super glue and paint thinner. Thanks to new dynamic materials developed at the University of Illinois, removable paint and self-healing plastics soon could be household products. U. of I. materials science and engineering professor Jianjun Cheng, graduate student Hanze Ying and postdoctoral researcher Yanfeng Zhang published their work in the journal Nature Communications. “The key advantage of using this material is that it’s...

Nobody knows the remarkable properties of human skin like the researchers struggling to emulate it. Not only is our skin sensitive, sending the brain precise information about pressure and temperature, but it also heals efficiently to preserve a protective barrier against the world. Combining these two features in a single synthetic material presented an exciting challenge for Stanford Chemical Engineering Professor Zhenan Bao and her team. Now, they have succeeded in making the first...

Smart, Self-healing Hydrogels Have Possibilities In Medicine, Engineering

[ Watch the Video ] University of California, San Diego bioengineers have developed a self-healing hydrogel that binds in seconds, as easily as Velcro, and forms a bond strong enough to withstand repeated stretching. The material has numerous potential applications, including medical sutures, targeted drug delivery, industrial sealants and self-healing plastics, a team of UC San Diego Jacobs School of Engineering researchers reported March 5 in the online Early Edition of the Proceedings...

When one tiny circuit within an integrated chip cracks or fails, the whole chip — or even the whole device — is a loss. But what if it could fix itself, and fix itself so fast that the user never knew there was a problem? A team of University of Illinois engineers has developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink. Led by aerospace engineering professor Scott White and materials science and...

New Self-Healing Fluids Could Prevent Cracks In Material
2011-09-29 12:32:48

University of Illinois researchers have found a way to pump self-healing fluids around a material similar to an animal's blood circulation. Self-healing materials have been the focus of many scientists for close to a decade, all hoping to reduce the risks and costs of cracking and damage in a wide range of materials. Researchers have taken different approaches in creating self-healing materials, but this is the first that took a page out of nature itself. Professor Nancy Sottos and...

A Pitt and Carnegie Mellon team developed a new model of how self-repairing materials function and show that materials with a certain number of easily breakable bonds can absorb more stress, a natural trick found in the resilient abalone shell, according to a report in Langmuir Conventional rules of survival tend to favor the strongest, but University of Pittsburgh-based researchers recently found that in the emerging world of self-healing materials, it is the somewhat frail that survive....

Michael Kessler has worked with polymers that repair themselves when they crack. And he's worked with polymers made from vegetable oils. Now he's working to combine the two technologies. Kessler, an Iowa State University associate professor of materials science and engineering and an associate of the U.S. Department of Energy's Ames Laboratory, is researching and developing biorenewable polymers capable of healing themselves as they degrade and crack. "If successful, the results of this...
