consistent with the fact that the percent crystallinity of the beta
phase increases with lower cooling rates, since an increased
melting temperature and increased percent crystallinity typically
occur together. The lack of change in the melting temperature
of the alpha phase can be explained, since the fraction of the
alpha phase decreased with lower cooling rates; however, the
result must be considered moderately surprising. Further, if
recrystallization is occurring, then possible changes in the
location of the alpha peak could be masked. Unlike the percent
of each polymorph, no clear difference was found in melting
temperatures between the samples with and without nanotubes,
except that the melting temperature of the alpha phase was
slightly higher in the samples without nanotubes.
