| 摘 要： | 采用差示扫描量热法研究铸型(MC)尼龙/Dy_2O_3纳米复合材料的非等温结晶行为,并利用Caze法和Mo法对结晶动力学进行分析,运用Kissinger方法计算MC尼龙的结晶活化能.结果表明,纳米Dy_2O_3起到异相成核的作用,使MC尼龙的结晶峰温升高,结晶总速率增大;添加纳米Dy_2O_3使MC尼龙的结晶活化能增大.

| Abstract: | The nonisothermal crystallization kinetics of MC nylon6/Dy_2O_3 nanocomposites were studied by differential scanning calorimetry (DSC). The Caze method and the Mo method were applied to analyze the nonisothermal crystallization kinetics. The Kissinger method was used to estimate the activation energy for nonisothermal crystallization. The results showed that the nano-Dy_2O_3 had a heterogeneous nucleation effect in the polymer matrix, the MC nylon6 composite' s peak crystallization temperature raised and th... |
