Electrokinetic properties of bare or nanoparticle-functionalized textile fabrics

Electrokinetic properties of bare or (polymethyl methacrylate) polymer nanoparticles-functionalized textile fabrics have been investigated via streaming potential measurements as a function of various parameters such as pH, salinity, nanoparticles adsorption and washing steps. The cationic nanoparticles adsorption has been performed on synthetic or natural textiles via static depletion method and the surface modification induced by nanoparticles adsorption has been studied in direct relation with the adsorbed nanoparticles amount. In addition, desorption of pre-adsorbed nanoparticles has been investigated and special attention has been dedicated to the effect of residual nanoparticles on the electrokinetic properties of the used textile fabrics.
