在本文中，我们使用层层（LbL）纳米组装沉积的聚（苯胺磺酸）（SPAN）薄膜的高灵敏度和快速响应的湿度传感器的制造。旋涂也用于制造基于SPAN I的湿度传感器以进行比较。当设备暴露在湿度下时，监测传感膜的薄层电阻的变化。对于5%的相对湿度变化，从逐层的和旋涂的湿度传感器测量的灵敏度分别为11%和6%。这些逐层组装的装置的预期应用是在一次性手持仪器中，以监测湿度敏感环境中湿度的存在。(c)2005 Elsevier B.V.保留所有权利。
In this paper, we use layer-by-layer (LbL) nano-assembly for deposition of ultrathin poly(anilinesulfonic acid) (SPANI) films for fabrication of highly sensitive and rapid response humidity sensors. Spin coating was also used for fabrication of SPANI based humidity sensors for comparison. The change in electrical sheet resistance of the sensing film was monitored as the device was exposed to humidity. For 5% change in relative humidity, the sensitivity was measured to be 11 and 6% from layer-by-layer based and the spin coated humidity sensors, respectively. An intended application for these layer-by-layer assembled devices is in disposable handheld instruments to monitor the presence of humidity in humidity sensitive environments. (c) 2005 Elsevier B.V.
