| 中文摘要 | surface morphology of polystyrene (ps) films on different substrates by spin-coating before and after annealing was observed using atomic force microscopy (afm). the effects of polymer molecular weight, substrates, solvents, and annealing conditions on the morphology of the films were investigated. before annealing, the grain height decreases, and simultaneously the grain diameter increases with molecular weight (m-w) within the measured molecular weight. after annealing. the situation is opposite, i.e., the grain height increases while the grain diameter decreases with m-w. furthermore, after annealing the smaller surface roughness (ra) was obtained. it was also found that film surface roughness (ra) depends on the vapor pressure and dipole moment of different used solvents as well as the substrates. the experimental results show that when the used solvents have similar dipole moment but different vapor pressure, the ra of ps film decreased with the decreasing vapor pressure of solvents whether on silicon or on mica. and when the used solvents have close vapor pressure but different dipole moment, the ra decreased with the increasing of solvent dipole moments on both substrates. |
