摘　　要：利用聚吡咯(PPy)导电聚合物构建的气体传感器可检测常见的无机气体和可挥发性有机物(VOCs)。综述了PPy基气体传感器的制备、气敏机制及其在气体检测方面的应用。影响其气敏性能的重要因素包括掺杂(特别是质子酸掺杂)、复合或填充处理、制备工艺、被检测气体或蒸气的性质及外界条件等。The gas sensors based on polypyrrole（PPy） have been widely used in detecting various inorganic gases or volatile organic compounds （VOCs）. The preparation, gas-sensing mechanism and application of the PPybased gas sensors are reviewed. Doping, especially protonic acid doping, is an important factor influencing the gas sensing property of the materials. Furthermore, the composition or loading and preparation process of PPy, the nature of gas or vapor detected and environmental conditions remarkably affect the gas-sensing property of the materials. Finally, the new development trends of the PPy gas sensors are discussed.
