柔性PANI-SnO2复合薄膜的制备及其对NH3的气敏特性

论文摘要

以苯胺与二氧化锡（SnO2）为前体,通过将原位化学氧化聚合法与静电吸附相结合,在柔性衬底聚酰亚胺（PI）上制备了聚苯胺-二氧化锡（PANI-SnO2）复合薄膜。通过傅里叶红外光谱（FTIR）、扫描电子显微镜（SEM）与X射线衍射（XRD）对复合薄膜的结构与形貌进行表征,证实了PANI-SnO2的成功合成与复合。对其在室温条件下进行了一系列气敏性能测试,结果表明SnO2的添加有效提升了PANI对氨气（NH3）的响应能力;该PANI-SnO2复合薄膜对体积分数为1×10-5～6×10-5的NH3具有良好的灵敏度,此外,该复合薄膜具有良好的重复性与选择性;而且在进行弯折处理后,PANI-SnO2对NH3的响应值并无明显变化。上述结果都表明PANI-SnO2复合薄膜对NH3的检测具有实际应用价值。
