  在此,我們報告一個新的簡單的方法製備聚苯胺磁性奈米複合PANI-Fe3O4。此方法利用四氧化三鐵奈米微粒作為氧化劑協助紫外線合成PANI- Fe3O4磁性奈米複合材料。

  FTIR and XRD analyses confirm that polyaniline has been obtained in the emeraldine salt form and that the mean diameter of the Fe3O4 nanoparticles before synthesis was of the order of 25 nm; for the PANI-Fe3O4 nanocomposite in HCl after 4 h of reaction, the mean diameters were of the order of 11 nm.

            FT-IR和XRD分析證實,已取得聚苯胺在emeraldine salt的形式,四氧化三鐵奈米粒子的平均直徑合成前是25奈米;為PANI- Fe3O4奈米複合材料在HCl反應4 h後,平均的直徑為11奈米。

  The dc conductivity results for the pure magnetite were about 2.4×10−6 Scm−1, while the nanocomposites were of the order of 10−5 Scm−1, confirming the increase in conductivity with the increasing amount of PANI.
  純磁鐵礦的直流電導率約為2.4 ×10-6 Scm-1,而奈米複合材料大約10-5 Scm-1 ,確認增加聚苯胺越多導電性也越多。
