摘要：

Higher conductivity of electrospun nanofiber mat was observed by four-terminal resistance measurement compared to polyaniline (PANI)/Polyethylene oxide (PEO) film based on the same doping method. In order to improve conductivity of the blended polymer and guarantee its spinability in the meanwhile, the concentration of PEO with great molecular weight of 5,000,000 could be decreased to 0.10wt%. The influences of voltage, electrode-to-collector distance and flow rate as well as environmental humidity in electrospinning process on the nanofiber morphology were respectively discussed in detail. PANI/PEO nanofiber mat can be used repeatedly for sensing NH3 gas. The response time is as short as about 6s and it can recover in 6 minutes when exposed to air.
