采用聚乙烯醇为基质材料制备了聚苯胺/聚乙烯醇(PANI/PVA)复合膜,讨论了PANI与PVA质量比、膜干燥温度对复合膜性能的影响,并对PVA膜、HCl掺杂PANI膜以及PANI/PVA复合膜的拉伸断裂强度、断裂伸长率、电导率以及热稳定性作了比较。结果表明:PVA膜的拉伸断裂强度、断裂伸长率最强,但是电导率最小;PANI/PVA复合膜电导率最大,其拉伸断裂强度、断裂伸长率比未加PVA的HCl掺杂PANI膜都得到了大大提高。在180℃之前,PVA膜最稳定,HCl掺杂PANI膜稳定性最差;在260℃之后,HCl掺杂PANI膜最稳定,PVA膜稳定性最差。 Polyaniline / polyvinyl alcohol (PANI / PVA) composite films were prepared by using polyvinyl alcohol as matrix material. The effects of mass ratio of PANI to PVA and the drying temperature on the properties of the composite films were investigated. PANI / PANI Tensile strength, elongation at break, electrical conductivity and thermal stability of PANI / PVA composite films were compared. The results showed that the tensile strength and the elongation at break of PVA film were the strongest, but the conductivity was the lowest. The conductivity of PANI / PVA composite film was the highest, its tensile strength at break and elongation at break were higher than those without PVA PANI film has been greatly improved. Before 180 ℃, the PVA film was the most stable and HCl-doped PANI film had the worst stability. After 260 ℃, HCl-doped PANI film was the most stable and PVA film was the worst.
