摘要
采用真空蒸发的方法交替沉积Ag和TCNQ分子制备了Ag TCNQ金属有机双层膜。研究了在大气,真空室,干燥器,饱和蒸汽室,水浸没5种不同环境下Ag TCNQ络合物形成过程中双层膜中的传质情况。结果显示氧气对传质过程基本无影响;而随着环境湿度的增加,传质速度显著加快,并采用一种电化学反应机制对这种加速现象做出了解释。
Ag-TCNQ thin films with different thickness were prepared by alternately vacuum depositing Ag and TCNQ. The transport in Ag-TCNQ thin films under different conditions was studied. The results showed that the transport process is accelerated with the increase of environmental humidity. A mechanism of electrochemistry is proposed to explain this phenomenon.
