Latest Self-healing plastic Stories
A new genre of plastics that mimic the human skin's ability to heal scratches and cuts offers the promise of endowing cell phones, laptops, cars and other products with self-repairing surfaces.
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.
When one tiny circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss.
Michael Kessler has worked with polymers that repair themselves when they crack.
Scientists in California are reporting development of a new generation of the microcapsules used in carbon-free copy paper, in which capsules burst and release ink with pressure from a pen.
Adding a food additive to damaged polymers can help restore them to full strength, say scientists at the University of Illinois who cooked up the novel, self-healing system.
Will the day come when cracks in buildings close up without external help and before they get to the stage where they cause damage to the component? This might appear utopia, but it already occurs in nature. When a person suffers a minor wound, the human body reacts to close the opening, sending the blood platelets needed to the affected area â€“ and with no need in many cases for any external coagulant substance to be employed.
