Dielectric response of polymer films confined between mica surfaces
The thin-film dielectric response of organic films confined within a surface forces apparatus ~SFA! and also between parallel sheets of atomically smooth mica is reported for the first time. Analysis is presented to infer dielectric properties of the organic film from the measured capacitance of the total system: sample, and mica sheets intervening between sample and electrodes. Measurements co...
متن کاملCerium Extraction from Solution by Adsorbing Colloid Flotation (ACF)
In this research, cerium recycling was studied by Adsorbing Colloid Flotation (ACF). Ten important parameters including collector type and dosage, cerium and colloid concentrations, frother type, activator type, preparation and frothing time, air flowrate and pH, each in two levels, were investigated. Statistical design of experiment was implemented for process modelling and analysis of var...
متن کاملRelaxation Times of Nano-Colloid Flocculation Induced by Adsorbing and Non-adsorbing Polymers
We have developed a self-consistent field theory of the effective interactions between nano-colloids mediated by adsorbing and non-adsorbing polymers. By making use of this theory, we have calculated the colloid immersion energy and the potential of the polymer-mediated forces for the above cases of polymer adsorption. On the basis of the obtained results for the polymer-mediated potentials, we...
متن کاملToward a Force Spectroscopy of Polymer Surfaces
The adhesional forces between a series of polymer film surfaces and chemicallywell-defined atomic force microscopy tips have been measured and found to depend strongly on the chemical nature of both probe and sample surfaces. For a given series of polymers, the ranking in adhesion strength was markedly different for polar and nonpolar probes, irrespective of the precise chemical composition of ...
