Cadmium telluride/polypyrrole nanocomposite based Love wave sensors highly sensitive to acetone at room temperature

Cadmium telluride/polypyrrole (CdTe/PPy) nanocomposites are synthesized and integrated into Love mode surface acoustic wave (L SAW) sensors, achieving high sensitivity to various volatile organic compounds including acetone, ethanol, and toluene. Chemical/physical analysis of the composites and thei...
