igs. 3 and 4, and the corresponding data are reported in
Table 1. NR is an amorphous material; therefore, the
cooling and heating scans did not show any crystallization
or melting peaks for the NR samples but showed only a
PCL crystallinity phase. In the heating process, the melting
temperature (Tm) increased by *8 % with respect to neat
PCL. The Tm of the pure PCL mat was 56.5 C, whereas
the Tm of the 50 % NR samples increased to 63.5 C,
followed by a reduction from 57.2 to 48.4 % in the crystallinity
(see Table 1). This result suggests that the addition
of NR suppressed the melting of the PCL crystals, even for
samples with similar or lower degrees of crystallinity.
