摘要：

Humidity sensing response of conducting polymer composite such as Polyaniline-Neodymium Oxide (PNO) composite with varying wt% of Nd2O3 in PANI [PANI-Nd2O3-10% (PNO-1), PANI-Nd2O3-30% (PNO-2) and PANI-Nd2O3-50% (PNO-3)] was studied. These samples were prepared by in situ chemical polymerization and were structurally and morphologically characterized by various analytical techniques. Humidity sensing performance of the PNO composites was evaluated in the range of 11-97% RH. Composite PNO-3 showed the highest sensing response of 99% with a response and recovery times of 28 and 29 s, respectively. Other sensing parameters like hysteresis, limit of detection, and sensing stability were also determined for the composites.
