| 英文摘要 | On a non-wetting solid substrate, the solvent annealing process of a thin polymer film includes the swelling process and the dewetting process. owing to difficulties in the in situ analysis of the two processes simultaneously, a quantitative study on the solvent annealing process of thin polymer films on the non-wetting solid substrate is extremely rare. in this paper, we design an experimental method by combining spectroscopic ellipsometry with optical microscopy to achieve the simultaneous in situ study. using this method, we investigate the influence of the structure of swollen film on its dewetting kinetics during the solvent annealing process. the results show that for a thin ps film with low m-w (m-w = 4.1 kg mol(-1)), acetone molecules can form an ultrathin enriched layer between the ps film and the solid substrate during the swelling process. the presence of the acetone enriched layer accounts for the exponential kinetic behavior in the case of a thin ps film with low m-w. however, the acetone enriched layer is not observed in the case of a thin ps film with high m-w (m-w = 400 kg mol(-1)) and the slippage effect of polymer chains is valid during the dewetting process. |
