的Flory-Huggins混合自由能被证明是适当的时间演变的聚苯乙烯和聚(甲基丙烯酸甲酯)的三元共混物的分析过程中,从甲苯旋涂使用原位光散射技术。对于所研究的浓度范围,在相同的甲苯体积分数下发生膜不稳定性的发作和散射环的观察。Flory-Huggins理论的成功表明,聚合物链在旋涂过程中保持无规行走特性。同时得出结论,成膜过程中的相分离热力学与初始溶剂浓度无关。
The Flory-Huggins free energy of mixing is shown to be appropriate for the analysis of the temporal evolution of a ternary blend of polystyrene and poly (methyl methacrylate) during spin-coating from toluene using anin-situlight scattering technique. For the range of concentrations studied, both the onset of film instability and the observation of a scattering ring occur at the same toluene volume fraction. The success of Flory-Huggins theory indicates that polymer chains retain random walk characteristics during spin-coating. It is also concluded that the thermodynamics of phase separation during film formation is independent of the initial solvent concentration.
