摘　　要：导电聚合物是包含有sp2杂化结构的共轭聚合物,可以使电荷离域传输。本文介绍了导电聚合物分别与碳纳米管、石墨烯、金属纳米颗粒或者金属氧化物纳米颗粒杂化复合,研究其吸附、催化反应、电荷传输等方面的性能。共轭聚合物与纳米颗粒相互作用或产生响应,可以作为敏化剂来提高纳米颗粒的敏感性,降低检测限,缩短响应时间,提高对惰性物质的选择性,进而提高传感器性能。本文主要论述了一些经过杂化的导电聚合物化学电阻传感器用于气体检测的现状以及杂化传感器未来的发展方向。Conducting polymers,or conjugated polymers,are a kind of polymers containing a sp2 structure that permits delocalized transport of charge carriers.Here these polymers are examined in the context of nanoscale hybridization with carbon nanotubes,graphene,metal nanoparticles or metal oxide nanoparticles,to amplify adsorption,catalytic reaction and transport behavior of additional material systems.Conjugated polymers act as conduits that interface and respond to nanoparticle interactions or conversely play the role of the sensitizing agent to enhance sensitivity,lower detection limit,response time or selectivity of relatively inert substances,ultimately giving rise to high performance sensors.This review is focused on hybrid conducting polymer sensors for detection of gaseous chemicals with discussing several recent reports along with strategies for further development of hybrid sensors.
