由疏水的二甲基双十八烷基铵（多达）壳和包封的亲水的多氧阴离子核组成的表面活性剂包封的簇（SEC）可以形成流延膜。流延膜的结构受有机溶剂的蒸发速率的影响。当通过缓慢蒸发氯仿来制备流延膜时，烷基链被认为具有部分叉指，并且叉指长度为1.6nm。通过扫描力显微镜（SFM）、傅里叶变换红外光谱（FT-IR）、广角X射线衍射和差示扫描量热法（DSC）对流延膜结构进行了表征。(C)2002 Elsevier Science（美国）。
The surfactant-encapsulated cluster (SEC) composed of a hydrophobic dimethyl dioctadecyl ammonium (DODA) shell and an encapsulated hydrophilic polyoxoanion core can form casting films. The structure of the casting film is influenced by evaporation rates of organic solvent. When the casting films are prepared by slow evaporation of chloroform, the alkyl chains are considered to possess a partial interdigitation, and the interdigitated length is 1.6 nm. The casting film structure is characterized by scanning force microscopy (SFM), Fourier transformation infrared (FT-IR), wide-angle X-ray diffraction, and differential scanning calorimetry (DSC).
