摘要: 通过在不同加热速度、不同坩埚材料和不同样品质量条件下测定In,Zn,Sn,Pb等元素的熔点,校正了加热速度对差示扫描量热仪显示温度的影响.根据对仪器温度校正的结果,研究了Ni33Zr67,Zr65Al7.5Ni10Cu15Co2.5,Pt69.0Ni9.6P21.4,聚醚砜(PES)和聚苯乙烯(PS)等材料的玻璃转变的动力学特征结果表明,玻璃转变温度与加热速度对数成正比,且这种关系并不违反Vogel-Fulcher定律.根据测量的玻璃转变温度和Vogtl-Fulcher定律计算了材料的理想玻璃转变温度和玻璃转变激活能.

Abstract:The apparent temperatures on Differential Scanning Calorimeter were calibrated by measuring the melting temperature of In, Zn, Sn and Ph with different heating rates, different crucibles and different sample weights. Based on the calibrated results, the kinetic characteristics of the glass transition for Ni33Zr67, Zr65Al7.5Ni10Cu,,Co2.5,Pt69.0Ni9.6P2104, polyethersulfone and polystyrene were studied. The results show that there is a linear relation ship between the logarithm of heating rates and the glass transition temperatures. It is argued that this linear relationship is not against the Vogel-Fulcher law. According to the measured glass transition temperatures and Vogel-Fulcher law, the ideal glass transition temperature and the activation energy for the glass transition were calculated.
