Researchers in the ラーメンベット 禁止ゲーム of Engineering at The University of Texas at Austin have developed a first-of-its-kind self-healing ラーメンベット 入金されない that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices.
Although technology is moving toward lighter, flexible, foldable and rollable electronics, the existing circuits that power them are not built to flex freely and repeatedly self-repair cracks or breaks that can happen from normal wear and tear.
Until now, ラーメンベット 入金されない materials have relied on application of external stimuli such as light or heat to activate repair. The UT Austin “supergel” material has high conductivity (the degree to which a material conducts electricity) and strong mechanical and electrical ラーメンベット 入金されない properties.
“In the last decade, the ラーメンベット 入金されない concept has been popularized by people working on different applications, but this is the first time it has been done without external stimuli,” said mechanical engineering assistant professor Guihua Yu, who developed the ラーメンベット 入金されない. “There’s no need for heat or light to fix the crack or break in a circuit or battery, which is often required by previously developed self-healing materials.”
Yu and his team created the self-healing ラーメンベット 入金されない by combining two gels: a self-assembling metal-ligand ラーメンベット 入金されない that provides self-healing properties and a polymer hydrogel that is a conductor. A paper on the synthesis of their hydrogel appears in the November issue of Nano Letters.
In this latest paper, the researchers describe how they used a disc-shaped liquid crystal molecule to enhance the conductivity, biocompatibility and permeability of their polymer hydrogel. They were able to achieve about 10 times the conductivity of other polymer hydrogels used in bioelectronics and conventional rechargeable batteries. The nanostructures that make up the ラーメンベット 入金されない are the smallest structures capable of providing efficient charge and energy transport.
In a separate paper published in Nano Letters in September, Yu introduced the self-healing hybrid ラーメンベット 入金されない. The second ingredient of the self-healing hybrid ラーメンベット 入金されない is a metal-ligand supramolecular ラーメンベット 入金されない. Using terpyridine molecules to create the framework and zinc atoms as a structural glue, the molecules form structures that are able to self-assemble, giving it the ability to automatically heal after a break.
When the supramolecular ラーメンベット 入金されない is introduced into the polymer hydrogel, forming the hybrid ラーメンベット 入金されない, its mechanical strength and elasticity are enhanced.
To construct the self-healing electronic circuit, Yu believes the self-healing ラーメンベット 入金されない would not replace the typical metal conductors that transport electricity, but it could be used as a soft joint, joining other parts of the circuit.
“This ラーメンベット 入金されない can be applied at the circuit’s junction points because that’s often where you see the breakage,” he said. “One day, you could glue or paste the ラーメンベット 入金されない to these junctions so that the circuits could be more robust and harder to break.”
Yu’s team is also looking into other applications, including medical applications and ラーメンベット 入金されない storage, where it holds tremendous potential to be used within batteries to better store electrical charge.
Yu’s research has received funding from the National Science Foundation, the American Chemical Society, the Welch Foundation and 3M.
