Anodic aluminum oxide (AAO) is a promising material for sensor applications due to its unique nanoporous structure and high surface area. This study investigates enhancing AAO’s sensing capabilities by incorporating carbyne-enriched nanomaterials. research aimed create novel acoustic wave (SAW) with improved performance characteristics. AAO films were fabricated using two-step anodization process, followed coating deposition via ion-assisted pulse-plasma deposition. The dielectric properties of the resulting composite characterized impedance spectroscopy, while was evaluated exposing various ethanol concentrations. results showed significant increase in capacitance permittivity carbyne-filled compared pristine AAO, along 5-fold improvement sensitivity vapor. increased attributed synergistic combination area carbyne’s electrical properties. work demonstrates successful fabrication characterization high-sensitivity gas sensor, highlighting potential advanced applications.
