非离子表面活性剂层状液晶的结构与增溶作用

相行为研究表明，与ＴｒｉｔｏｎＸ－１００／Ｃ＿６Ｈ＿６／Ｈ＿２Ｏ体系相比，ＴｒｉｔｏｎＸ－１００／Ｃ＿（１０）Ｈ＿（２１）ＯＨ／Ｈ＿２Ｏ体系更易于生成层状液晶，并更为稳定，小角Ｘ－射线衍射表明；ＴｒｉｔｏｎＸ－１００／Ｃ＿（１０）Ｈ＿（２１）ＯＨ／Ｈ＿２Ｏ体系层状液晶中，Ｃ＿（１０）Ｈ＿（２１）ＯＨ与ＴｒｉｔｏｎＸ－１００交替排列于两亲双层中，Ｃ＿（１０）Ｈ＿（２１）ＯＨ／ＴｒｉｔｏｎＸ－１００重量比增加，两亲双层厚度ｄ＿０值不变。以Ｃ＿６Ｈ＿６代替Ｃ＿（１０）Ｈ＿（２１）ＯＨ后，Ｃ＿６Ｈ＿６存在于两亲双层的油层和渗入ＴｒｉｔｏｎＸ－１００分子链尾周围，使得溶剂渗透率减少，并且Ｃ＿６Ｈ＿６／ＴｒｉｔｏｎＸ－１００增加，ｄ＿０值增加。

Structure and Solubilization of Non-ionic Surfactant Lamelar Liquid Crystal

The phase diagrams showed that for Triton X-1 00/C_(10)H_(21) OH/H_2O system thelamellar liquid crystals were formed more easily and were more stable than Triton X-100/C_6H_6/H_2O system lamellar liquid crystals. SAXD showed that C_(10)H_(21)OH and Triton X-100are arranged in turn in the amphipathic-layer of Triton X-100/C_(10)H_(21)OH/H_2O lamellar liquidcrystal and that the thickness of the layer d_0 was independent of the weight ratio of C_(10)H_(21)OHto Triton X-100. When C_6H_6 was used instead of C_(10)H_(21)OH as in Triton X-100/C_6H_6/H_2Olamellar liquid crystals,the d_0 values increased with increase of weight ratio of C_6H_6/TritonX-100.
