Figure 2
The autocorrelation functions obtained from PS films (123 kg mol−1) with thickness of (a) 1Rg, (b) 2Rg and (c) 4Rg at 468 K for q = 7.7 × 10−3 nm−1. Solid lines are single exponential fits. The fitted relaxation time constants for the 2Rg and 4Rg films are labeled. There are no dynamics observed for the 1Rg film. |
