The results of the dispersion and intercalation/exfoliation of clay C30B in EPON828-D230 prepared by different pre-mixing methods are shown in Table 2 (results from X-ray diffraction (XRD) and field emission gun scanning electron microscopy (FEGSEM
Scanning electron microscope (SEM) observations were performed using a field emission gun SEM (FEGSEM
) Hitachi S-4700.
A Hitachi-S4700 field emission gun scanning electron microscope (FEGSEM
) was used to observe the dispersion of clay in the epoxy matrix at the micro-level with different magnifications of 1 k, 3 k, 10 k, and 40 k.
A field emission gun scanning electron microscopy (FEGSEM
; Hitachi--4700) with the working operation voltage of 2 kV was used to observe the microdispersion of the samples.
The observation was made on a field emission gun scanning electron microscopy (FEGSEM
; HITACHI S-4700), with the working operation voltage of 2 kV.
Apart from their nanodistribution, characterized by TEM and XRD analysis in a previous paper (23), the distribution of the clay particles in the materials at the micro-scale was also characterized by FEGSEM
(Hitachi S4700) observations and image analysis.
Cross-sectional images of the final composite films were obtained using a Hitachi S-800 field emission-gun, scanning electron microscope (FEGSEM
