中文摘要：为制备兼具力学性能和导电性能的氨敏传感器基体材料,采用一种水浴静电纺丝法连续制备涤纶工业丝为芯,聚酰胺6纳米纤维为皮层的纳米纤维包覆纱(NCY),并采用原位聚合法对其进行导电处理,制备表面负载聚吡咯的导电纳米纤维包覆纱(NCY/PPy),借助扫描电子显微镜和傅里叶红外光谱仪对NCY和NCY/PPy进行表面形貌和化学结构分析,同时研究了NCY/PPy的导电性能、力学性能、氨敏性能。结果表明,NCY具有超高的比表面积;经导电处理后,负载的聚吡咯未堵塞纤维之间的空隙,纳米纤维包覆层仍保持多孔网状结构,当吡哜浓度为0.07 mol/L时,NCY/PPy的电导率达7.19×10^(-2) S/cm;高比表面积的纳米结构导电层,有利于提高气敏传感器对氨气的敏感性。

外文摘要：In order to prepare the substrate material of ammonia sensor with both mechanical and electrical properties,nanofiber coated yarns(NCY)with polyester industrial yarn as core and polyamide 6 nanofiber as skin was continuously prepared by a water bath electrostatic spinning method,and conductive treatment was carried out by in-situ polymerization to prepare conductive nanofiber coated yarns(NCY/PPy)with polypyrrole on the surface.The surface morphology and chemical structure of NCY and NCY/PPy were analyzed by means of scanning electron microscope and Fourier transform infrared spectrometer.Meanwhile,the conductivity,mechanical properties and ammonia sensitivity of NCY/PPy were studied.The results show that NCY has an extremely high specific surface area.After conducting treatment,the loaded polypyrrole does not block the gap between the fibers,and the nanofiber coating still maintains the porous network structure,and when the polypyrrole is 0.07 mol/L,the conductivity of NCY/PPy is 7.19×10^(-2) S/cm.Nano-structured conductive layer with high specific surface area is beneficial to improve the sensitivity of gas sensor to ammonia.
