The flocculation efficiency of polydisperse polymer flocculants
The flocculation performance of three poly(acrylic acid) (PAA) samples (Mw = 9 10, 2.5 10 and 1 10 g/mol) has been investigated. Colloidal alumina particles were used as a model system and tests were performed at pH 5. Using a singlecomponent polyacid, it was found that the optimum dosage required to achieve supernatant clarity was similar between the 9 10 g/mol PAA (23 ppm) and 2.5 10 g/mol PA...
متن کاملShear-induced structure in polymer-clay nanocomposite solutions.
The equilibrium structure and shear response of model polymer-clay nanocomposite gels are measured using X-ray scattering, light scattering, optical microscopy, and rheometry. The suspensions form physical gels via the "bridging" of neighboring colloidal clay platelets by the polymer, with reversible adsorption of polymer segments onto the clay surface providing a short-range attractive force. ...

متن کاملVisualization of cortex organization and dynamics in microorganisms, using total internal reflection fluorescence microscopy.
TIRF microscopy has emerged as a powerful imaging technology to study spatio-temporal dynamics of fluorescent molecules in vitro and in living cells. The optical phenomenon of total internal reflection occurs when light passes from a medium with high refractive index into a medium with low refractive index at an angle larger than a characteristic critical angle (i.e. closer to being parallel wi...
متن کاملInfluence of Polymer-Clay Interfacial Interactions on the Ignition Time of Polymer/Clay Nanocomposites
Metal ions present on smectite clay (montmorillonite) platelets have preferential reactivity towards peroxy/alkoxy groups during polyamide 6 (PA6) thermal decomposition. This changes the decomposition pathway and negatively affects the ignition response of PA6. To restrict these interfacial interactions, high-temperature-resistant polymers such as polyetherimide (PEI) and polyimide (PI) were us...
