Polyacid brush

In one example polymer segment density profiles of weak polyacid brushes consisting of polymethacrylic acid (PMAA) chains were investigated as a function of the pH of the environment by means of multiple-angle ellipsom-etry [68]. The polymer brushes were prepared by surface-initiated polymerization of methylacrylic acid as described above. [Pg.109]

Fig. 21 Profiles of a surface-attached weak polyacid brush as obtained from FT analysis of ellipsometric data at different pH. The pH is given in the figure. Analysis of the same ellipsometric data by Fresnel modeling. Best fits to complementary error functions at different pH given in the figure. For more details see text...

PAA is a typical weak polyacid and has been widely used as a model to investigate protein-polyelectrolyte interactions. BallaulTs group systematically studied BSA adsorption on so-called "spherical polyelectrolyte brushes" (SPBs) consisting of a polystyrene (PS) core covered with PAA brushes (as shown in Figure 7.4)... [Pg.174]
