摘　　要：以等离子体引发聚合的方式在高浓度下得到高产率的聚苯胺(PANI)纳米纤维,并将PANI纳米纤维与聚二甲基硅氧烷(PDMS)混合制备了柔性应变传感器。通过扫描电子显微镜(SEM)、X射线衍射(XRD)、红外光谱(FTIR)、电化学性能测试手段等表征了聚苯胺纳米纤维的结构、组成以及传感器的性能。结果表明,等离子体处理时间的增加,聚苯胺纳米纤维的长径比会逐渐减小,聚苯胺的氧化程度和结晶度会逐渐提高,而产率则呈现出先增后降的趋势;聚苯胺纳米纤维浓度越高,传感器灵敏度越低,稳定性越好。In this paper,high yield polyaniline(PANI)nanofibers were obtained at high concentration by plasma initiated polymerization.At the same time,flexible strain sensor was prepared by mixing nanofibers with polydimethylsiloxane(PDMS).The structure and constitutes of PANI nanofibers and the performance of sensor could be characterized by scanning electron microscope,X ray diffraction,fourier transform infrared spectroscopy and electrochemical performance test.The results show that with the increase of plasma treatment time, the length-diameter ratio of polyaniline nanofibers could gradually decrease,the oxidation degree and crystallinity of polyaniline could gradually increase and the yield could increase firstly and then decrease.The higher the concentration of polyaniline nanofibers in PDMS,the sensor could show the lower sensitivity and the better stability.
