摘　　要：综述了本征型导电聚合物(ICPs)基气敏材料的制备方法及影响其气敏性能的各种因素。制备ICPs气敏材料的主要方有电化学聚合或沉积、化学氧化聚合和气相聚合,影响其气敏性能的重要因素有掺杂(特别是质子酸掺杂)、对ICPs进行复合或填充处理、ICPs气敏材料的制备工艺、被检测气体或蒸气的性质以及外界条件等。The preparation methods and influencing factors of intrinsically conducting polymers （ICPs） as gas sensing materials were reviewed. The ICPs can be prepared by electrochemical pblymerization or deposition, chemical oxidation and vapor-phase polymerization. Doping, especially protonic acid doping, the composition or loading and preparation process of ICPs, the nature of gas or vapor detected and environmental conditions are important factors influencing the gas sensing property of the materials. Finally, the advantages and disadvantages of ICPs as gas sensing materials were discussed.
