Abstract
モノグリセライドとH2Oの2成分系がつくるリオトロピック液晶を,偏光顕微鏡を使って観察した。その結果,ニート相,粘性等方相そして逆ミドル相の3相が安定相として確認され,相転移は粘性等方相と他の2相とのあいだで可逆であることがわかった。リオトロピック液晶成長の様子も観察された。
Abstract
The lyotropic liquid crystalline phases of the monopalmitin-H2O system have been investigated by means of a polarizing microscope.
As a result, the three stable phases of the monoglyceried-H2O system were observed, as being respectively the neat phase, the reversed middle phase and the viscous isotropic phase. It is concluded that the phase transitions both from the viscous isotropic phase to the neat phase and from the viscous isotropic phase to the reversed middle phase are reversible processes. This is contrary to Wilton et al's result for the phase diagram of the monostearin-H2O system.
The patterns of the lyotropic liquid crystal growth were observed in relation to those of the smectic liquid crystal. Their growth mechanism is discussed too.
