摘要
选取环氧树脂固化物为样品,分别采用DSC法和DMA法测定了其玻璃化转变温度。结果表明,玻璃化转变温度随测定方法和条件的不同而变化,因此,在给出某种材料的玻璃化转变温度时,必须注明测定方法和条件。
The glass transition temperature (Tg) of epoxy resin was measured by means of differential scanning calorimetry (DSC) and dynamical mechanical analysis (DMA). The results showed that the glass transition temperature of the polymer changed with the different measurement methods and conditions. The different measurement methods often obtain different results. When comes to the glass transition temperature of some kind of polymer, it must be given clear indication of the measurement methods and conditions.
