We report the study of the equilibrium and dynamic properties of Langmuir monolayers of poly(styrene-co-maleic anhydride) partial 2-buthoxyethyl ester cumene terminated polymer and the effect of the Mg(NO(3))(2) addition in the water subphase on the film properties. Results show that the polymer monolayer becomes more expanded when the electrolyte concentration in the subphase increases. Dense polymer films aggregate at the interface. The aggregates are transferred onto silicon wafers using the Langmuir-Blodgett methodology and the morphology is observed by AFM. The structure of aggregates depends on the subphase composition of the Langmuir film transferred onto the silicon wafer.
我们研究了聚(苯乙烯-co-马来酸酐)部分 2-丁氧基乙酯芐基封端聚合物的朗缪尔单分子层的平衡和动态性质,以及水亚相中添加 Mg(NO(3))(2)对膜性质的影响。结果表明,当亚相中的电解质浓度增加时,聚合物单层变得更加伸展。致密的聚合物薄膜在界面处聚集。使用 Langmuir-Blodgett 方法将这些聚集体转移到硅晶片上,并通过 AFM 观察其形貌。聚集体的结构取决于转移到硅晶片上的 Langmuir 薄膜的亚相组成。
