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。
(PDADMAC) is adsorbed on the quartz surface. The adsorption mass of SiO2 nanopartieles 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.
