英文摘要	Surface tethered weak polyelectrolyte, carboxylated poly(OEGMA-r-HEMA), was prepared via surface initiated polymerization (SIP) from metal (Au, Pt and Ag) surfaces functionalized with initiators through metal-S bonds. The swelling behavior of carboxylated poly(OEGMA-r-HEMA) in phosphate buffered saline (PBS) was studied by quartz crystal microbalance (QCM) and was found to obey the following equation: T(eff) = (0.32ln([Na(+)]) + 2.53) x T(COOH,dry), where T(eff) and T(COOH, dry) are the thicknesses of carboxylated poly(OEGMA-r-HEMA) in PBS measured by QCM and in air measured by ellipsometry, respectively. We also confirmed that the event of covalent bond breaking (CBB) of Au-S bonds occurred at a certain critical T(eff), i.e. similar to 255 nm. Thus, one could predict the CBB of Au-S or other metal-S bonds from the swelling behavior of surface tethered carboxylated poly (OEGMA-r-HEMA).
