摘 要：The bi-functional carbazole-based photorefractive polyphosphazenes with different content of C60-doped were fabricated. The glass transition temperature（Tg） of these polymer composite materials was determined using a differential scanning calorimetric（DSC） method. According to the DSC measurement results with different heating rates, the variation of Tg and the active energy of glass transition（Eg） were analyzed in detail. The analysis results indicate that the transition region shifts to higher temperatures with increasing heating rate, and C60 content（below 1.0 wt%） can influence the Tg of photorefractive polyphosphazenes. The Tg first increases and then decreases with the C60 content（below 1.0 wt%）. The probable causes of the influence of C60 on Tg was proposed.
