用小角中子散射和中子反射率研究了水-辛烷-四甘醇单癸基醚（C{sub 10}E{sub 4}）双连续微乳液的体相和表面结构。当微乳液中表面活性剂单分子膜的亲水性和疏水性平衡时，发现表面相关长度显著大于其本体类似物。改变单分子膜的自发曲率极大地影响微乳液的表面结构，而对体积相关函数的影响相对较小。这些观测结果可以用金兹伯格-朗道理论来解释。
Small angle neutron scattering and neutron reflectivity are used to study the bulk and surface structure of water--octane--tetraethylene glycol monodecyl ether (C{sub 10}E{sub 4}) bicontinuous microemulsions. When the hydrophilicity and hydrophobicity of the surfactant monolayers in the microemulsion are balanced, the surface correlation length is found to be significantly larger than its bulk analog. Varying the spontaneous curvature of the monolayers greatly influences the surface structure of the microemulsion while having a relatively slight effect on the bulk correlation function. These observations are explained using a Ginzburg-Landau theory.
