morphology with droplets of PMMA. Scan size is 4μm×4μm, d) schematic representations of bicontinuous-dispersed
phase morphology with small droplets of black phase, e) FIB-AFM image
of 10/30/60 HDPE/PS/PMMA showing bi-continuous/dispersed phase morphology with
droplets of HDPE. Scan size is 11.7μm×11.7μm, and f) SEM micrograph of 10/30/60
HDPE/PS/PMMA after extraction of PS. Small droplets of HDPE are distributed in PS
Note that in the schematics, black represents the HDPE phase, grey represents the PS phase and
white represents the PMMA phase.
6.4.5 Triangular Composition/Morphology Diagram
Thirty different samples comprised of various compositions of HDPE/PS/PMMA (Figure 6-8a))
were prepared to better understand the composition dependance of the various morphological
