Dewetting Behavior of PMMA on PS-brush Substrates |
| 초록 |
Grafting polymer molecules onto polymer brushes has become a common procedure to precisely tune the surface properties such as adhesion, lubrication, slip and the wettability of the surfaces. We present experimental results quantifying the dewetting behavior of poly(methyl methacry-late)(PMMA) melt on polymer brushes of polystyrene(PS) molecules. Our studies indicate contact angles which display brush molecular weight dependence similar to that expected for autophobic dewetting situation. We use strong-segregation theory calculations to model the interfacial tension behavior in our observations and delineate the interplay between enthalpic and entropic effects in polymer wetting upon polymer brushes. |
