Fig. 2.30 (A and B) Mechanical properties of RPET-OMMT system at various clay loading
[60].
Pegoretti et al. [62] have prepared the rPET/organoclay nanocomposites at several
nanoclay content (1, 3, and 5 wt%). This works suggested the highest stiffness
and tensile strength at 5 wt% of nanoclay. Bizarria et al. [63] have observed
that the same composition that obtained same result while T g slightly decreased by
the clay content may be due to clay agglomeration that occurred above a critical clay
loading [64,65].
