Abstract
Silver nanowires (AgNWs) transparent electrodes have recently been selected as an alternative conductor for use in various electronic devices. The synthesis of AgNWs for a flexible wearable antenna is successfully demonstrated on PDMS/PVDF elastomeric substrate. In order to consider its suitability for use in flexible antenna applications, the structural properties of AgNWs-polymeric film are discussed. This type of flexible antenna is prepared using the casting method by embedding the AgNWs on the surface of the PDMS/PVDF elastomeric substrate. Analysis of FTIR and SEM showed that AgNWs are reliably transferred to the elastomeric substratum surface, which then served as a conductive radiating factor for the antenna system. Uniform average porosity suggested sponge formation as a porous structure on the film surface that is beneficial for the AgNWs catchment area. The as-made AgNWs-polymeric substrate revealed antennas shaped − 18 dB return loss with a frequency of 2.725 GHz. These results have shown the feasibility of this AgNWs’ polymer film in wireless communications’ applications for wearable systems.
