| 内容記述 | Sodium cellulose sulfate (NaCS)-based polyurethane (PU) hydrogels were prepared from the solution of NaCS and hexamethylene diisocyanate (HDI). Water content (W_c) of the obtained PU hydrogels was less than 3.0 g g^<-1> and NCO/OH ratio was varied from 0.05 to 0.6 mol mol^<-1>. Phase transitions of NaCS and NaCS-PU hydrogels were measured by differential scanning calorimetry (DSC). From DSC curves, glass transition temperature (T_g), melting peak at low temperature (T_<ml>), melting peak at high temperature (T_<mh>) and liquid crystal transition temperature (T_<lc>) were obtained. It was also confirmed that there were three kinds of water, non-freezing water, freezing bound water, and freezing water. T_g decreased in a W_c from 0.05 to 1.0 g g^<-1>, reached a minimum and then increased W_c from 1.0 to 3.0 g g^<-1>. The T_g lowest value increased with increasing NCO/OH ratio indicating that molecular motion was restricted by cross-linking. The nano level structures of NaCS and NaCS-PU hydrogels were observed by atomic force microscopy (AFM). | |||||
