From hybrid and electric vehicles to underground exploration of fossil-fuels, our search for energy solutions has increasingly placed us in situations demanding electricity storage and delivery under extreme conditions. Though batteries are the reigning storage technology, capacitors are an alternative with several advantages: they’re lightweight, they can be charged and discharged relatively quickly, and they don’t lose their storage capacity over time. In order to function properly, capacitors require dielectric materials, which behave as insulators and are essential for charge storage. Polymeric dielectrics have enhanced performance over other materials, and they can operate under more intense electric fields without failing (termed higher breakdown strength) and greater reliability. They also have the added benefit of practicality, being scalable, lightweight, and easily manipulated. Right now, their major drawback as a material is their inability to work at high temperatures, like those required in many applications. But a composite polymer has finally been developed that seems to break down the traditional limitations of these materials, promising to open up a broader range of uses. Scientists made the new material by crosslinking a traditional polymer embedded with flakes of boron nitride nano sheets. Read 12 remaining paragraphs | Comments
