00:00Scientists develop gel that self-heals similar to human skin.
00:05Researchers from Aalto University and the University of Bayreuth have developed a self-healing gel technology that mimics human skin's self-healing properties and high stiffness.
00:16This breakthrough, overcoming prior limitations, opens doors to novel applications, including wound healing, artificial skin, and drug delivery systems.
00:30The hydrogel structure incorporates ultra-thin clay nanosheets, creating a highly ordered matrix with densely entangled polymers, enhancing mechanical strength and self-repair.
00:42Monomers mixed with nanosheets in water are exposed to UV light, bonding molecules into an elastic gel.
00:49Polymer layers randomly twist in a state called entanglement.
00:53The polymers in the self-healing gel become fully entangled, indistinguishable, and highly mobile.
00:58When cut, they quickly intertwine again, demonstrating significant self-healing ability.
01:05Researchers observed that the gel self-healed by 80-90% within 4 hours and fully healed in 24 hours.
01:13A 1mm thick gel layer contains 10,000 nanosheet layers, providing its unique stiff yet flexible quality akin to human skin.
01:22This dual nature may initially seem paradoxical, but is crucial for its functionality.
01:27The self-healing gel technology has transformative potential for drug delivery, wound healing, and prosthetics, offering durability and comfort.
01:36In soft robotics, it enables artificial skin that self-repairs.
01:41Wearable tech could benefit through self-repairing textiles, while aircraft and construction could use it for damage-resistant coatings.
01:48Researchers refining this breakthrough may greatly impact numerous industries.
