摘　　要：基于层接层分子自组装技术,利用导电聚合物聚噻吩(PT)、聚苯胺(PAN)和聚吡咯(PPY)建立了一种仿生嗅觉传感薄膜分子模型,使PT、PPY和PAN的原位聚合导电高分子形成聚阴离子或聚阳离子,并交互沉积进行自组装,生成多层薄膜。这种薄膜能在0.01 cm2的面积上集成一定数目的嗅觉分子传感器,理论上可以对不同的气味分子产生相应的响应信号。A molecular model of bionic olfactory sensing ultrathin film was built based on the layer-by-layer （LBL） self-assembly technology. The in situ polymerized conducting polymers polythiophene （PT） , polypyrrole （PPY） and polyaniline （PAN） were delocalized into polycation or polyanion and was used to fabricate self-assemble muhilayer thin films by consecutively alternating deposition. Then a novel fabrication model for bio-olfactory sensing uhrathin films with a certain number of mimetic olfactory sensor on an area about 0.01 cm^2 was presented. Theoretically, the ultrathin films can response to different odors with corresponding molecule-level electron signal.
