Abstract: C1.00265 : The T$_{g}$ of polycyanurate in cylindrical nanoporous confinement
Author:
The glass transition behavior of materials under nanoconfinement
is often different than their behavior in the bulk. A leading
explanation is that enhanced mobility at free surfaces or neutral
interfaces results in depressions in Tg, whereas attractive
interfaces result in increases in Tg. In this work, we examine
the Tg of a polycyanurate using differential scanning calorimetry
for both material confined in cylindrical nanopores and for
freely-standing nanocylinders. Preliminary results using an alumina
nanofilter for the confining matrix indicate that the Tg
depression for the supported and freely standing nanocylinders
are similar. The implications of the results will be discussed.
