Phase transition behavior of water sorbed into various polymers (with low water content) and adhesion of fibroblast to their polymers were examined. The adhesion behaviors did not have a correlation with chemical structure, glass transition temperature, and water content of the polymers. Temperature variable infrared spectroscopy revealed the existence of phase transition of a part of the sorbed water, which was generally assigned as "non-freezing (non-freezable) water" by differential scanning calorimetry. Phase transition observed here were not only crystallization and melting but also condensation, vapor deposition, sublimation, revapor-deposition, and vaporization. These results gave a new insight for water structure in water-polymer systems. However, there was no correlation between the fibroblast adhesion to the polymers and the phase transition behavior of water.

研究了不同聚合物（低含水量）吸水后的相变行为及成纤维细胞与聚合物的粘附。聚合物的化学结构、玻璃化转变温度和含水量与其粘接性能无关。变温红外光谱表明部分吸附水发生了相变，差示扫描量热法将其称为“非冻结水”。这里观察到的相变不仅结晶和熔化，而且冷凝，气相沉积，升华，再气相沉积，和蒸发。这些结果为水-聚合物体系中水的结构提供了新的认识。然而，成纤维细胞粘附到聚合物和水的相变行为之间没有相关性。
