Abstract
A three-dimensional (3D) lamellar structure of a poly(styrene-block- isoprene) block copolymer was observed at submicrometer and micrometer levels by scanning electron microscopy combined with a focused ion beam (FIB-SEM). The 3D lamellar structure with an exceptionally large periodicity, about 0.1 /mi, was successfully reconstructed, and the size of the reconstructed image by FIB-SEM was 6.0 × 6.0 × 4.0 μm3, which was greater than the transmission electron microtomography data, 3.8 × 3.9 × 0.24 μm3, by a factor of about 40. This result indicates that 3D reconstruction using FIB-SEM is quite useful for direct 3D observations, especially analyses of polymeric materials at the submi crometer and micrometer levels.
