. In the PHB matrix, nanoparticle dispersion was
found to be hindered by a high level of polymer crystallinity with
full nanoparticle dispersion achievable only at low nanoparticle
loadings. The impact of nanoparticle aggregation was seen in trends
in the peak melting temperatures, the peak crystallization
temperatures, and crystallization half-times where maximum
changes in these quantities were seen for dispersed nanoparticles.
The dynamic mechanical property trends showed a lesser dependence
on the level of nanoparticle aggregation
