项目摘要
Using temperature-variable infrared spectroscopy, recrystallization phenomena (crystallization of water molecules during the heating process) observed for water molecules incorporated in blood-compatible polymer materials could be ascribed to state changes of monomeric or oligomeric water molecules and not to the transition of amorphous ice to crystal ice, which denied the presence of water molecules having a specific hydrogen-bonded network. Furthermore, the infrared measurements of water molecules incorporated in several kinds of polymer materials without blood compatibility indicated the presence of recrystallization phenomena, too. Comparing the glass transition temperature with the composition of elements in the polymers indicated that the recrystallization phenomena are strongly related to the mobility of polymer chains and the electrostatic interaction between water molecules and the polymers.
使用可温度变化的红外光谱法,在血液兼容聚合物材料中掺入的水分子观察到的重结晶现象(在加热过程中的结晶现象)可以归因于单体或寡聚水分子的状态变化,而不是与冰冰的特定冰层的过渡,而不是冰冰的过渡,而冰层的冰层却是冰层的,而冰层的冰层则是冰向的。此外,在没有血液兼容的几种聚合物材料中纳入水分子的红外测量也表明存在重结晶现象。将玻璃过渡温度与聚合物中元素的组成进行比较表明,重结晶现象与聚合物链的迁移率以及水分子与聚合物之间的静电相互作用密切相关。
