| 英文摘要 | The mechanism of inhibition of polymer film dewetting is investigated by adding a star comb-like polymer, four-arm P(S-ran-VB-g-PMMA), to PS film and PMMA film on different substrates. It is found that the mechanism of inhibition of polymer film dewetting is kinetic in nature, and is related to the miscibility between the additional compound and the polymer film. On addition to the miscible system [four-arm P(S-ran-VB-g-PMMA) and PMMA], the star comb-like polymers can increase the resistant force of dewetting with hole growth and inhibit the dewetting process of the thin polymer film by enrichment in the rim. To the immiscible system [four-arm P(S-ran-VB-g-PMMA) and PS], firstly the four-arm P(S-ran-VB-g-PMMA) enriches the solid substrate and forms nanodroplets in the process of spin-coating, and then PS film dewets on these nanodroplets; however, the star comb-like polymer can inhibit the dewetting of the polymer film only when the contact angle theta of the polymer on the additional four-arm P(S-ran-VB-g-PMMA) is smaller than that of the polymer on the substrate. |
