摘要
分别研究了盐酸(HC l)掺杂的聚苯胺和十二烷基苯磺酸钠-盐酸(SDBS-HC l)掺杂聚苯胺导电薄膜在四氢呋喃(THF)气体中的敏感行为,实验表明,相比盐酸掺杂的聚苯胺薄膜敏感行为,SDBS-HC l掺杂聚苯胺薄膜在四氢呋喃(THF)气体中敏感行为显示出较高的响应度,更好的可逆性和线性,以及快速的响应性。因此,SDBS-HC l掺杂聚苯胺薄膜有望成为一个很好的传感材料。
Response of polyaniline conducting polymers (PANI) doped with hydrochloric acid (HCI) or sodium dodeeylbenzenesulfonate-HCl (SDBS-HCl) were researched respectively to tetrahydrofuran (THF) saturated vapor at room temperature. The experimental results indicated that the SDBS-HCl doped PANI film showed an excellent sensing for THF vapor, higher sensitivity, better reversibility and faster response time than the HCl dopped PANI film. Therefore polyaniline (PANI) doped with (SDBS-HCl) film will make a good sensing material in the future.
