Two types of half-esters of succinic acid have been prepared. One
contains a 1,2-dialkylated glyceryl group, while the other has a normal
alkyl group as the hydrophobic group. The mono-molecular films of the
half-esters developed at the airâwater interface were evaluated
byÏâA curves. Multilayer
LangmuirâBlodgett (LâB) films deposited on the substrate are
discussed in terms of pinhole defects. Influences of the surface pressure
on accumulation, the number of layers, and the chain length of the
lipophilic group are analysed. The LâB film made from the
double-chained homologues possessed fewer pinhole defects compared with
that composed of the single-chained one.
已制备了两种丁二酸半酯类型。一种包含1,2-二烷基化的甘油基团,而另一种则具有正常的烷基作为疏水基团。通过π-A曲线评估了这些半酯在气-水界面上形成的单分子膜。关于基板上的多层Langmuir-Blodgett(L-B)膜,就其针孔缺陷进行了讨论。分析了表面压力对累积、层数和亲脂性基团链长的影响。由双链同系物制备的L-B膜相比于单链同系物制备的膜具有更少的针孔缺陷。
