纳米SnO_2及分子筛封装纳米SnO_2簇的湿敏性能研究

The Studies on Humidity sensitivity of Nano SnO 2 and Zeolite Entrapped Nano SnO 2 Clusters

本文以液相法制备的纳米ＳｎＯ２微粉和分子筛封装的纳米ＳｎＯ２簇微粉为原料，采用涂膜法制作成湿敏元件，并且分别对这两种元件进行了湿敏性能的测试。研究表明纳米ＳｎＯ２微粉和分子筛封装的纳米ＳｎＯ２簇微粉，其湿敏元件灵敏度明显高于普通ＳｎＯ２微粉，阻湿线性关系良好，具有较好的湿敏性能。

The humidity sensitive properties of nano SnO 2 prepared by liquid phase method and zeolite entrapped nano SnO 2 Clusters are measured, The two sensors have high sensitivity and good linear characteristics.
