Abstract: S1.00014 : New methods to characterize the confinement effects in epoxy nanocomposites
Author:
Properties of epoxy can be improved/controlled via the addition of nanofillers.
However, use of nanofillers leads to confinement and interfacial effects and the exact
nature of these two effects on the properties are not yet clearly understood. In this
study, the glass transition temperature of epoxy nanocomposites was investigated. The
changes in the glass transition temperature were analyzed as a function of nanofiller
content (confinement) and epoxy-nanofiller interface. In addition to these, the
distribution and dispersion of nanoparticles also influences the properties. We applied
two different methods to characterize the interparticle distance and compare the
dependence of glass transition temperature on the nanofiller content and interparticle
spacing. We found that our model provides a new understanding of the effect of
interparticle spacing on glass transition phenomenon in polymeric nanocomposites.
