“…Therefore, 15 wt % MoS 2 @CC/SE composites not only present flexibility and a suitable balance between dielectric constant and losses but also withstand relatively high temperatures without deterioration of dielectric properties. This is particularly important to fulfill the vital requirements of microstrip antennas during the long-term performance in adverse environmental conditions …”

“…This is particularly important to fulfill the vital requirements of microstrip antennas during the long-term performance in adverse environmental conditions. 64 Compared to composites based on ceramic powders, natural fibers, and metal laminates for potential use in microwave components and substrates, 15 wt % MoS 2 @CC/SE composites achieve comparable or higher dielectric constant together with very low losses (Table 1). Moreover, composites in Table 1 employ complex fabrication procedures such as high temperature, hazardous chemicals, and additive manufacturing, and they are also based on rigid matrices.…”

With the miniaturization and integration of electronic components in wireless communication and wearable devices, the demand for low-cost flexible composites with temperature-stable high dielectric constant and low loss has substantially increased. However, such comprehensive properties are fundamentally difficult to combine for conventional conductive and ceramic composites. Here, we develop silicone elastomer (SE) composites based on hydrothermally grown MoS 2 on tissue paper-derived cellulose carbon (CC). Such design promoted the formation of microcapacitors, multiple interfaces, and defects reinforcing interfacial and defect polarizations and resulting in a high dielectric constant of 9.83 at 10 GHz with low filler loading of 15 wt %. Unlike highly conductive fillers, MoS 2 @CC with low conductivity ensured a very low loss tangent of 7.6 × 10 −3 , which was also influenced by the filler dispersion and adhesion to the matrix. Apart from breaking the typical conflict between high dielectric constant and low losses of traditional conductive composites, MoS 2 @CC SE composites were highly flexible with temperature-stable dielectric properties making them attractive as flexible substrates in microstrip antenna applications and extreme environment electronics. Moreover, recycling from waste tissue paper makes them potential candidates as low-cost and sustainable dielectric composites.

“…Recent demand for state‐of‐the‐art high temperature sensor electronics for newer applications require specific parameters, especially concerned with satisfying the demands for monitoring chemical manufacturing plants, combustion turbines and engines, combustion reactors and agricultural waste processes, namely pyrolysis, boilers, furnaces, and heat pumps. [ 39 ] Printed high‐temperature resistance‐temperature detectors (RTDs) use the resistance variation of printed CuNi conductors with temperature change for temperature determination. [ 40 ] Similar to all other printed sensors, several factors need to be considered to achieve high temperature sensitivity, namely the material, configuration, resistance temperature coefficients (TCR), oxidation resistance, and manufacturing requirements.…”

As the modern electronic technology extends into operating in harsh working conditions, it calls for a system that is capable of uncompromising performance in extreme environments, thus providing a strong motivation to look for advanced materials and electronics with the capability of high‐throughput and rapid prototyping. Coupled with additive manufacturing, molecular decomposition metals bypass the challenging oddities of traditional material‐limited and thermally initiated metalworking, enabling high throughput and rapid prototyping of stoichiometry and composition‐controlled metals. Here, a new paradigm for the design and additive manufacturing of copper metallic alloy materials onto ceramics is described by printing molecular decomposable metal materials, capable of withstanding thermo‐mechanical loading, operating in extreme environments in static and dynamic conditions. The resulting printed hybrid electronics are electrically stable for 25 h of aging at 1000 °C. This curious fact paves a way for printed antenna and sensor electronics that reliably operate up to 1000 °C. These results can be further extended to establish other printable molecular decomposable materials as a platform for rapid prototyping of high temperature electronics that are suitable for harsh environments.
