| 摘 要： | 以无水A lC l3为催化剂合成了聚苯乙炔(PPA)、用浓H2SO4进行磺化改性,并通过共混制得了PPA/碳纳米管(CNT)及磺化PPA/CNT复合材料;研究了复合材料的导电性及电导率与CNT含量的关系。结果表明:磺化PPA/CNT导电阈值比PPA/CNT的降低了1%,前者达到极限电导率所需CNT的量是后者的10%;X-射线衍射(XRD)测试表明,在CNT界面上的磺化PPA有新的晶型产生。

| Abstract: | Polyphenylacetylene(PPA) were prepared with anhydrous AlCl_3 as catalyst,and sulfonated by concentrated H_2SO_4.The conductivity of PPA/carbon nanotubes(CNT) and sulfonated PPA/CNT composites prepared by mixing CNT with polymer in tetrahydrofuran under sonication were studied.The(result) shows that the room temperature conductivity of the two kinds of composites is enhanced with the (ratio) of CNT increasing,the estimated percolation threshold of sulfonated PPA/CNT is 1% less than that of PPA/CNT,and the amount of CNT that are added to PPA for obtaining the maximum conductivity is 10% of that of the sulfonated PPA.The XRD suggests that the CNT effects the crystal structure of the polymer by interface action. |
