摘要
In this article, we propose a facile chemical fabrication strategy for the synthesis of Bi2O3 nanoparticles/ CNT homophonous nanohybrid for a humidity sensing device development at room temperature. We use a simple bar coating method to prepare Bi2O3 nanoparticles and CNT hybrids. Then the morphology and structure of Bi2O3/CNT are studied using X-ray diffraction, Transmission electron microscopy and other surface area measurements. The humidity sensing properties of the sensor is investigated at room temperature under a variety of analytical value. Bi2O3/CNT nanohybrid with average pore size of ∼22.2 nm displays proportional stable response toward increasing humidity values (from relative humidity (RH) level 0%–90%) and reveals better linearity than pure Bi2O3 (indistinguishable at RH60%+) and higher response (∼90%) than pure CNT (∼15%).
