Abstract
The melting temperature depression of pentaerythritol tetranitrate,
nanoconfined in controlled pore glasses (CPG), was systematically
studied by differential scanning calorimetry (DSC). The solid-liquid
interfacial energy sigma (sl) was obtained from the Gibbs-Thomson
equation fit to melting temperature vs. reciprocal pore diameter. The
pore size distribution of the CPG pores was also estimated from the DSC
data. Pore sizes obtained from the manufacturer by BET are compared with
those determined from the DSC curves using either the curves directly or
by assuming spherical shaped confining cavities. The thermal mass vales
are in better agreement with the BET estimation.
