AFM force measurements have been performed to study the influence of the pH value and salt concentration on the interactions between poly(2-vinyl pyridine) brushes and microsized silica spheres, focusing on attractive and adhesion forces. It was found that the interaction

We reported the deliberate control on the micelle opening and closing of amphiphilic polystyrene-block-poly(2-vinylpyridine) (PS-b-P2VP) micellar films by exposing them to selective solvents. We first treated the micellar films with polar solvents including ethanol and water (pH = 4, 8

Conformations of cationic polyelectrolytes (PEs), a weak poly(2-vinylpyridine) (P2VP) and a strong poly(N-methyl-2-vinylpyridinium iodide) (qP2VP), adsorbed on mica from saline solutions in the presence of counterions of different valences are studied using in situ atomic force microscopy (AFM). Quantitative characteristics

The effect of perchlorate ions as counterions in the acid-induced swelling of poly(2-vinylpyridine) microgel particles was investigated. The pH was modified with perchloric, hydrochloric and hydrobromic acids and the particle diameter measured using dynamic light scattering and the viscosity monitored

The interaction between negatively charged organic salts, with one two and three sulfonate groups respectively, and positively charged poly(2-vinylpyridine) microgel particles has been investigated. Absorption isotherms are used to describe the uptake of organic salt into the microgel network and
