30/4/2002· SEM images were obtained using a Philips XL30S FEG SEM, operated between 1 and 5 keV. To prevent surface charging it was necessary to evaporate a thin Au layer (∼10 nm) onto the porous surfaces. This enabled us to obtain reasonable images of the surface; however, the Au layer itself blocked up the smallest pores (approximately <10–20 nm), and so prevented us from getting good images …
