用原子力显微镜(AFM)研究了丙烯酸酯乳液(分散)漆膜的表面，并通过红外光谱提供了辅助的化学信息。探讨了一系列新近浇铸的参考漆膜的表面形态和化学特征，包括对接触水和矿物油引起的变化的表征。一个便携式的原位原子力显微镜系统也被用来记录泰特收藏的丙烯酸乳胶画的表面。成功地将迁移的表面活性剂的全部和部分移除与机械作用产生的特征一起成像。除了采用湿法表面清洁处理外，还观察到油漆表面和迁移的表面活性剂层在颜料类型、油漆品牌和暴露于加速老化的情况下的差异。这些发现有助于进一步了解丙烯酸酯乳胶漆薄膜表面发生的细微变化，并与目前关于通过保护处理从这些薄膜中去除/干扰原始表面活性剂的争论有关。
The surfaces of acrylic emulsion (dispersion) paint films were investigated by atomic force microscopy (AFM), with supporting chemical information provided via infrared spectroscopy The morphological and chemical features of the surfaces of a series of recently cast reference paint films were explored, including characterization of changes induced by exposure to water and mineral spirits. A portable in situ AFM system was also used to document the surfaces if acrylic emulsion paintings in Tate's collection. The complete and partial removal of migrated surfactant was successfully imaged alongside features arising from mechanical action. Differences in paint surfaces and migrated surfactant layers were observed in relation to pigment type, paint brand and exposure to accelerated ageing, in addition to applied wet surface cleaning treatments. The findings contribute to further understanding of the subtle changes occurring at acrylic emulsion paint film surfaces and are relevant to current debates on the removal/disturbance of original surface surfactant from these films through conservation treatment.
