测定了Brij97/IPM/蔗糖溶液体系在37℃相图,并利用TA-2000ex旋转流变仪测定了组成和温度对Brij97/IPM/蔗糖溶液体系流变性质的影响,结果表明,当蔗糖溶液含量一定时,随Brij97/IPM比例的增大体系依次形成六角状液晶和层状液晶。动态流变性质测量表明,该两种液晶均显示较高的弹性性质。
The phase diagram of Brij97/IPM/Sucrose solution system was determined at 37℃. The effects of composition and temperature on rheology properties of Brij97/IPM/Sucrose solution system were determined by TA-2000ex rheometer. The results indicate that phase transition occurs from hexagonal to lamellar liquid crystal with increasing in Brij97/IPM ratio at the constant content of sucrose solution. Dynamic rheologieal results show this two kinds of liquid crystals investigated exhibit high elasticity.
