摘要:

掺杂樟脑磺酸的聚苯胺在纯水表面可以形成稳定的单分子层 ,采用Langmuir-Blodgett技术可以将其较好地转移到氟化钙基片上制成薄膜. 对其LB膜的红外和紫外-可见-近红外光谱研究表明 ,在膜的压缩或转移过程中有少量的樟脑磺酸分子发生脱掺杂的现象. 并且该LB膜在室温下对乙醇有较好的气敏性.

Abstract:

Stable monolayer of polyaniline doped with camphor sulfonic acid at the air water interface has been obtained and has been successfully deposited by Langmuir-Blodgett technique onto CaF2 substrate. IR and UV-Vis-NIR spectra show that the doped molecules dedoped partially from the PANI backbone during the monolayer compression or deposition. Gas sensing measurement indicates that the doped polyaniline LB film was sensitive to ethanol vapor at room temperature.
