Phys.org  August 19, 2024 Making the Internet of Things a reality will require the type of circuitry and advanced operations that are only possible with electronics that can function in both positive and negative voltage modes. Researchers in Canada developed a new material zwitterion composed of an imidazolium tethered to an anionic sulfonyl(trifluoromethane sulfonyl)imide group as an alternative dielectric material to traditional ionic liquids. The zwitterion not only melted below 100 °C but also proved to be nonhygroscopic. By blending this compound with poly(methyl methacrylate) over a range of concentrations and thicknesses, they made high-capacitance organic dielectric materials. Experiments suggested […]
