原子力显微镜（AFM）被用来研究丙烯酸玻璃片（PMMA）表面的老化和清洁效果，就像葡萄牙艺术家卢尔德·卡斯特罗（Lourdes Castro）使用的那样。测量是在透明（无色和蓝色）样品中进行的。样品在SolarBox中陈化；使用了与艺术家使用的类似的清洁和抛光产品。从AFM图像中确认了原始样品表面的开裂/划伤现象。实验导致表面粗糙度的增加，由于颗粒特征的存在，抛光样品的表面粗糙度更加明显。这些变化是由于亚克力片与抛光产品的相互作用，在有色样品中似乎更强。这些发现有助于确定延长这些材料寿命的最佳策略，特别是卢尔德·卡斯特罗创作的艺术作品。版权所有John Wiley & Sons， Ltd。
Atomic Force Microscopy (AFM) was used to study the ageing and cleaning effects on the surface of acrylic glass sheets (PMMA) like the ones used by the Portuguese artist Lourdes Castro. Measurements were done in transparent (colourless and blue) samples. The samples were aged in a SolarBox; cleaning and polishing products, similar to the ones applied by the artist, were used. From the AFM images the craze/scratch phenomena in the pristine samples surface was confirmed. The experiments led to an increase of the surface roughness, more pronounced for the polished samples due to the presence of granular features. These modifications are due to the interaction of the acrylic sheets with the polishing products, which seems to be stronger in the coloured samples. These findings are useful to define the best strategy to prolong the longevity of such materials, in particular the works of art created by Lourdes Castro. Copyright (C) 2010 John Wiley & Sons, Ltd.
