摘要：
The adsorption of anionic, carboxyl functionalized latex particles, recharged by a cationic surfactant acting as fabric softener/conditioner, to a cellulose surface was investigated with evanescent wave video microscopy. This technique allows to monitor the deposition and release of individual particles in real-time with an excellent selectivity and sensitivity. Since the recharged particles and the conditioner compete for the free surface, the initial deposition rate and final surface coverage are found to be strongly dependent on the ratio of particle and conditioner concentrations.
