压电传感器现场监测石英表面电荷分布

Piezoelectric sensor in situ monitoring charge distribution on quartz surface

理论上解析了石英表面电荷分布情况,利用双液隔电极压电传感器(ESPS)与溶液直接接触的特点,对阴、阳离子表面活性剂的吸附情况进行了现场监测,间接地证明了理论分析,这对传感器本身以及石英表面改性处理有重要参考价值。

*'The charge distribution on quartz surface was analyzed theoretically and was verified indirectly by adsorption of anionic surfactant and cationic surfactant onto the quartz surface using an electrodeseparated piezoelectric sensor (ESPS),which is in direct contact with solution.It is valuable for piezoelectric sensor itself and surface modification of quartz.
