The bi-functional carbazole-based photorefractive polyphosphazenes with different content of C_(60)-doped were fabricated. The glass transition temperature(T_g) 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 T_g and the active energy of glass transition(E_g) were analyzed in detail. The analysis results indicate that the transition region shifts to higher temperatures with increasing heating rate, and C_(60) content(below 1.0 wt%) can influence the T_g of photorefractive polyphosphazenes. The T_g first increases and then decreases with the C_(60) content(below 1.0 wt%). The probable causes of the influence of C_(60) on T_g was proposed. 展开更多
