文摘

A linear frequency-thickness (F-T) relation was established for surface-initiated atom transferradical polymerization (SI-ATRP) in a quartz crystal microbalance (QCM). This quantitative F-T relation ismonomer dependent but independent of polymerization rate, initiator and polymer density. With this F-T relationand the online monitoring capacity, QCM was successfully applied to study the kinetics of SI-ATRP mechanisms.QCM was also demonstrated to be useful in controlling film thickness at the angstrom level, which is critical innanofabrication.
