通过一步表面掺杂，p型有机纳米纤维材料获得了高的暗电导率。由此制造的纳米原纤复合材料已被证明在环境条件下是稳健的。高电导率，结合纳米纤维固有的大表面积，使化学电阻传感器的发展，微量蒸汽检测胺，检测限下降到十亿分之几的范围。
High dark electrical conductivity was obtained for a p-type organic nanofibril material simply through a one-step surface doping. The nanofibril composite thus fabricated has been proven robust under ambient conditions. The high conductivity, combined with the intrinsic large surface area of the nanofibers, enables development of chemiresistor sensors for trace vapor detection of amines, with detection limit down to sub-parts per billion range.
