The use of chronoamperometry to inspect the transport in a polymer brush grown from an electrode is illustrated in Figure 8.7. In this example, an electroactive species, such as ferricyanide ion (Fe(CN)/ ), is transported within a polyelectrolyte brush made of polycationic poly(2-methacryloyloxy)-ethyl-trimethyl-ammonium chloride (PMETAC), grafted by ATRP from an electrode. When the PMETAC brush coordinated with Fe(CN)5 is polarized...

Hilal et al. [25] studied the surface structure of molecularly imprinted poly(ether sulfone) membranes (called MIP membranes) by AFM and quantified the pore size and the surface roughness. They modified PES microfiltration membranes with a normal pore diameter of 0.22 j,m and a thickness of 150 (Am (Millipore). First, the membranes were coated with photoinitiator by soaking them in a 0.25 M solution of benzoin ethyl ether (BEE) in methanol and then immersing them in a mixture of 80 mM trimethyl propane trimethacrylate (TRIM), 40 mM 2-hydroxyethyl methacrylate (HEMA), and 2 mM adenosine 3 ,5 -cyclic monophosphate (cAMP) in an ethanol-water mixture (70 30 vol.%). Thereafter, the membranes were exposed to a B-100 lamp of relative radiation intensity 21.7 mW cm at 355 nm. Membranes with different modifications were obtained using various UV exposure times. The residual nongrafted polymer, monomer, initiator, and the template were extracted with methanol. After drying, the degree of modification (DM) was calculated from the...
