Study and Application of a Linear Frequency−Thickness Relation for Surface-Initiated Atom Transfer Radical Polymerization in a Quartz Crystal Microbalance

A linear frequency−thickness (F−T) relation was established for surface-initiated atom transfer radical polymerization (SI-ATRP) in a quartz crystal microbalance (QCM). This quantitative F−T relation is monomer dependent but independent of polymerization rate, initiator and polymer density. With thi...

Summary:A linear frequency−thickness (F−T) relation was established for surface-initiated atom transfer radical polymerization (SI-ATRP) in a quartz crystal microbalance (QCM). This quantitative F−T relation is monomer dependent but independent of polymerization rate, initiator and polymer density. With this F−T relation and 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 in nanofabrication.
