Summary: Composites of conductive polymers (CP) and metal oxides (MO) have been studied extensively in the past decade due to their unique electronic, electrochemical, catalytic, and mechanical properties. In this study, a novel method for synthesizing composite films of polyaniline (PANI) and indium oxide (InOx) with high electrical conductivities was proposed. The composite films consisted of two phases with graded concentration: InOx with oxygen vacancies and PANI with partially protonated molecular units. The PANI-InOx composite films exhibited enhanced electrochemical activity and efficient ion diffusion due to the open interfacial regions between the InOx and PANI phases.

Summary: This article presents a design strategy to improve the radiation efficiency of a planar antenna made of MXene conductor on a lossy PDMS substrate. New methods are proposed to reduce conductor loss and dielectric loss. By identifying the high current density location on the antenna radiator and redistributing the surface currents, the conductor loss is minimized. The dielectric loss is reduced by using a folded ground plane structure.
