At low frequencies
(< 10 rad/s), the addition of ENR to PLA resulted in enhanced G0
and G00 , this indicates that the epoxidized natural rubber is well dispersed
in PLA matrix because of the interaction between the epoxy
groups of ENR and carbonyl groups of PLA, this well dispersion produces
a percolation network which prevents the PLA chains from
free moving, and leads to the increase of G0 and G00.
