Figure 1. (a) Thicknesses of the PS (M_w = 225 kDa) flattened layers (h_flat) on PTS-75, PTS-85, and PTS-96 against the annealing time at 423 K. (b) The thickness h_flat on PTS-96 against the annealing time at 423 K for PS with various molecular weights. (c) Density of the PS (M_w = 225 kDa) flattened layer on quartz crystals with ��96% phenyl content as a function of annealing time at 423 K obtained from QCM data.

Figure 2. (a) Normalized ssp SFG spectra of the dPS/PTS-96 interface annealed at 423 K for the indicated annealing times. Spectra are offset for clarity. The black solid lines are the fitted curves. (b) Plots of the ratio of the peak area of the ��-�� stacking bond to that of the stretching band of the C-D bond on the benzene ring at 2288 cm^-1 vs the annealing time. The wavenumber of the peak of ��-��stacking () against the annealing time is shown in the inset. (c) Schematic illustration showing the evolution of the conformation of the flattened chains during the annealing process.
