摘要

石英表面先吸附阳离子聚电解质均聚二甲基二烯丙基氯化铵（PDADMAC）

利用压电式传感器实时监测纳米S iO2粒子在PDADMAC膜表面吸附过程中的质量变化

获得吸附速率常数

并讨论吸附可逆性和盐浓度的影响。

Abstract

Cationic polyelectrolyte polydiallyldimethylammonium chloride（PDADMAC） is adsorbed on the quartz surface.The adsorption mass of SiO

nanoparticles on pre-adsorbed PDADMAC film is monitored real time by an electrode-separated piezoelectric sensor.The rate constants for adsorption are estimated.The reversibility of adsorption and the influence of salt concentration are tested.
