Abstract
Abstract This article describes the fabrication of C60-doped carbazole-based bi-functional photorefractive polyacrylates, the C60-doped concentrations are 0.0, 0.2, 0.5, 0.7 and 1.0 wt.-%, respectively. For these photorefractive polyacrylates, differential scanning calorimetric runs have been taken under nonisothermal conditions at different heating rates. The result indicates that the glass transition temperature Tg first increases and then decreases with increasing of C60 content. Tg of the same sample increases with increasing heating rate. The activation energy of glass transition (Eg) has been evaluated based on the Moynihan and Kissinger model. The results showed that both Eg values obtained from Kissinger's and Moynihan's relations are in good agreement.
