reaction kinetics and properties of a monocyanateester and the resulting cyanurate trimer are studied using differential scanning calorimetry (DSC). On the basis of both dynamic heating scans and isothermal reaction studies, the reaction rate is found to increase with decreasing nanopore size without a change in reaction mechanism. Both the monocyanateester reactant and cyanurate product show reduced
使用差示扫描量热法(DSC)研究了纳米限制对单氰酸酯和所得氰尿酸酯三聚体的反应动力学和性能的影响。在动态加热扫描和等温反应研究的基础上,发现反应速率随纳米孔尺寸的减小而增加,而不改变反应机理。与本体相比,单氰酸酯反应物和氰尿酸酯产物均显示出降低的玻璃化转变温度(T g s)。该Ť克与转换抑郁症的增加和更明显的完全反应的产物,这表明分子刚度影响nanoconfinement影响程度。我们的结果与加速反应和先前发现的纳米限制的双官能氰酸酯的T g降低,支持环内环化不是这些作用的起源的假设。
