A poly acrylic acid (PAA) film has been fabricated on a quartz crystal microbalance to study the dynamic property changes induced by different pH values. The experiment has been performed by a two-step. First, using the self-assembly procedure, the gold surface of quartz crystal was chemically modified to allow the graft copolymerization with PAA. Secondly, the resonant frequency response of the PAA-modified QCM was investigated by varying the pH values. The result shows an interesting oscillation property change nearby pH 5.5, and a possible mechanism for the change is proposed considering the oscillation properties of quartz crystal and the physical properties of PAA. Finally, a polymer film complex of PAA/collagen was also used to confirm the proposed mechanism.
