Abstract
AbstractPoly {[2‐(methacryloyloxy)ethyl] trimethylammonium chloride} (PMETAC) brushes are synthesized by atom transfer radical polymerization from mixed monolayers of ω‐mercaptoundecyl bromoisobutyrate thiol (initiator) and 1‐undecanethiol (blank). Initiator density is varied from 100% to 1% by the molar ratio of initiator to blank in solution. Brush growth is followed in situ by a single device combination of a quartz crystal microbalance with dissipation (QCM‐D) and spectroscopic ellipsometry. Acoustic mass (macous) and optical mass (mopt) are simultaneously recorded. Brush hydration is calculated from the difference between macous and mopt. The percentage of water lost during brush collapse in NaCl solution at concentration from 10−3 M to 1 M is quantified for each initiator density.
