采用静电纺丝法制备了聚苯胺/聚环氧乙烷（ PANI/PEO）纳米纤维，研究了电压、接收距离对电纺PANI/PEO纳米纤维直径的影响，对电纺参数进行了优化。通过对电纺接收端的控制，制备了平行纳米纤维阵列，实现了纳米纤维的定向排布；通过对电纺射流沉积次数的控制，制备了PANI/PEO纳米单纤维传感器，并对NH3进行了气敏性测试。结果表明：当电纺电压为20 kV且接收距离为20 cm时，获得的PA-NI/PEO纳米纤维直径为105 nm，且形貌较佳，在此优化参数条件下制备的单纤维PANI/PEO纳米传感器在常温下对低浓度的NH3有良好的线性响应输出。

Polyaniline/polyethylene oxide( PANI/PEO)nanofiber is prepared by electrospinning,and effects of voltage and receiving distance on diameter of electrospinning PANI/PEO nanofiber are studied and electrospinning parameters are optimized. Parallel nanofiber arrays are prepared by controlling the receiver and orientation arrangement of nanofiber is realized;single nanofiber sensor is prepared by controlling deposition times of electrospinning solution jets and detect on NH3 . The result indicates that PANI/PEO nanofiber with diameter of 105 nm is prepared when the voltage is 20 kV and the receiving distance is 20 cm,and the PANI/PEO nanofiber sensor prepared under above optimized parameters has good linear response to low concentration NH3 at room temperature.
