A pH-responsive mixed polyelectrolyte brush from tethered polyacrylic acid (PAA) and poly(2-vinylpyridine) (P2VP) (PAA:P2VP = 69:31 by weight) was prepared and used for selective gating transport of anions and cations across the thin film. An ITO glass electrode was modified

Journal of colloid and interface science, 344(1), 112-116 (2010-01-20)
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
Yuri Roiter et al.
Nanoscale, 4(1), 284-292 (2011-11-15)
The mechanism of nanoparticle actuation by stimuli-responsive polymer brushes triggered by changes in the solution pH was discovered and investigated in detail in this study. The finding explains the high spectral sensitivity of the composite ultrathin film composed of a
Andreas Walther et al.
Chemical communications (Cambridge, England), (9)(9), 1127-1129 (2009-02-20)
We report on the unexpected finding of the formation of hydrophobic bridges between polybutadiene patches of multicompartment micelles based on amphiphilic miktoarm star terpolymers in water.

We report on the growth of gold nanoparticles in polystyrene/poly(2-vinyl pyridine) (PS/P2VP) star-shaped block copolymer monolayers. These amphiphilic PS(n)P2VP(n) heteroarm star copolymers differ in molecular weight (149,000 and 529,000 Da) and the number of arms (9 and 28). Langmuir-Blodgett (LB)
