An atomic force microscope （AFM） and a spectrophotometer were used to characterize the morphology of the surface layer of A1/Kapton films and their reflectivity. The results suggest that thermo-cycling and VUV radiation make the mass loss of Al/Kapton film samples, with the changes of surface morphology to some extent and significant decrease of reflectivity in the ultraviolet visible wave band.[著者文摘]
