Scanning electron microscopy (SEM) analyses
Qualitative evaluation ofthe degree of mixture (distribution and
dispersion ofthe TPC phase in TPS) was performed by using a model
JSM 6510 JEOL SEM, operating at a 5 kV. Samples were mounted
with carbon tape on aluminum stubs. Cross-sections of fractured
samples were mounted with the cross-section positioned upward
on the stubs. All specimens were sputter-coated with gold in a
sputter (Balzer, SCD 050).
