This paper explores the synthesis and properties of Polyaniline-Tungsten Oxide (PAni-WO3) nanocomposites based chemiresistor for the sensing of volatile organic compounds (VOCs), specifically α-pinene and limonene, which serve as biomarkers for malaria. The study emphasizes the need for effective VOC sensors due to their low boiling points and high vapor pressures, which result in significant health impacts when present at high concentrations indoors. Traditional detection methods, although accurate, are often costly, time-consuming, and require specialized personnel. This work presents the development of a cost-effective, environmentally friendly, and user-friendly sensor utilizing conducting polymers, particularly polyaniline, which is known for its stability, selectivity, and rapid response at room temperature. The PAni-WO3 nanocomposites were synthesized, and their morphological and crystalline structures were analyzed using Scanning Electron Microscopy and X-ray diffraction. Electrical studies were done to examine the transport properties of synthesized samples at room temperature. The sensing capabilities of these composites were evaluated by measuring resistance variations using the DMM6500 61/2 Digit Multimeter upon exposure to α-pinene and limonene. The resistance was found to vary as the concentration of VOCs increased from 1 to 5 ppm. The results demonstrate that PAni-WO3 nanocomposites offer promising sensitivity and selectivity for VOC detection at room temperature, making them suitable for real-world uses in health monitoring and environmental safety.
