T1 - High-resolution SEM with coupled transmission mode and EDX for quick characterization of micro- and nanocapsules for self-healing anti-corrosion coatings N2 - More and more sub-micro and nano-materials shall be "quickly", but accurately characterized with respect to their morphology, shape, size or size distribution, but also to the chemical composition as well by means of an SEM/EDX (Scanning Electron Microscopy / X-Ray Energy Dispersive Spectrometry) system. This undertaking is becoming successful indeed if the transmission mode at low voltages such as those at a SEM, i. e. mostly up to 30 kV, and EDX, respectively is employed. The transmission mode at conventional SEM can e "activated" firstly by re-defining the specimen to be analyzed and preparing it as a thin specimen, which is quasi-transparent to electrons and by finding a way of collecting only the transmitted electrons for analysis. The first issue can be easily realized by using the conventional TEM grids (and the respective sample preparation); the second one becomes feasible either (i) by placing a socalled STEM semiconductor detector directly under the thin specimen or (ii) by using a Special transmission set-up, which enables to the conventional Everhart-Thornley detector to collect only transmitted electrons by blocking the direct collection of secondary electrons and guiding only the transmitted electrons onto it.
