QCM signal response as a function of the mass (i.e., thickness) of the spin-coated PDMS cross-linked polymer film. The QCM responses, based on sampling 100 μg Tropine, are plotted on the ordinate. Film thicknesses larger than 400 nm resulted in a signal loss (i.e., the discontinuance of the fundamental resonant frequency). All measurements were repeated at QCM detector temperatures of 100 and 150 °C.
