Abstract

AbstractThe polymers have very good flexible properties such as bending, rolling, folding, and stretching capabilities with poor electric and dielectric response. On the other hand, electronic ceramics have suitable electric and dielectric response, but are lacking in flexible properties. New applications in flexible electronics material requires the property of flexibility as well as the electrical and dielectric properties. In this work, we have synthesized a composite material by taking ethylene vinyl acetate (EVA) as a polymer matrix and aluminum nitride (AlN) as an electronic ceramic material by the solution casting method and report the electrical and dielectric characteristics of the composite material. The XRD of ethylene vinyl acetate/aluminum nitride (EVA/AlN) composite material is studied for the presence of the AlN and EVA phase. The electrical and dielectric properties such as the capacitance (C), dielectric constant (ε), AC conductivity (σac), and the dielectric loss (tan δ) are obtained by the impedance spectroscopy in the frequency range of 1–1000 kHz. Its electric and dielectric responses are an indication of its suitability in the flexible electronics industry.KeywordsFlexible electronicsAluminum nitrideEthyl vinyl acetateDielectricDielectric loss (tan δ)AC conductivity
