摘要

Abstract

Since method of preparing polyaniline nanofibers doped with phosphoric acid is not reliable and reproducibility , acetic acid is introduced in aniline/phosphoric acid systems as a kind of co‐dopant , and key factors w hich can effect the formation of one‐dimensional polyaniline nanostructures are investigated . The result shows that acidity of the aqueous aniline/phosphoric acid solution can decrease ,and reaction rate between aniline and acids can reduce due to the addition of acetic acid .Meanwhile ,the temperatures of depositing w hite precipitate are changed . One‐dimensional polyaniline nanostructures can be synthesized as changing the content of acetic acid , and percentage of the polyaniline nanostructures in w hole polyaniline products can reach to 90% ~95% . Therefore , scope of reaction conditions for obtaining pure polyaniline nanofibers or nanotubes is broader , and stability and reproducibility of the fabrication process are improved . Conductivity of the polyaniline nanostructures is in the range of 2.9 × 10-2 ~ 1.4 × 10-4 S・cm -1 according to the ratio of phosphoric acid and acetic acid .
