Nano-coating of Metal Surface by Use of Supramolecular Film Whose Tensile Stress Is Promoted by the Mechanical press

为了研制一种新型的由分子层组成的涂层剂，利用一种两亲性的三亮氨酸衍生物对铁件表面进行防锈处理。具有非常简单的亲水基团的三亮氨酸衍生物，如羟基、巯基、羧基和氨基，不能防止铁表面生锈。这是因为这些简单的亲水基团很难附着在铁表面。另一方面，具有多个羟基的直链戊糖的三亮氨酸衍生物强烈地附着在玻璃和铁的表面上。它的防锈效果目前正在试验中。

In order to develop a new coating agent, which consists of amonomolecular layer, protection effect against rust was performed on the iron surface,by use of an amphiphilic trileucine-derivative. The trileucine-derivatives having a very simple hydrophilic group, such as a hydroxy, mercapto, carboxy, and amino group,has not prevent the iron surface from rust. This is because these simple hydrophilic groups were difficult to stick to the iron surface. On the other hand, the trileucine-derivative having a linear pentose head that has multiple hydroxy groupsstrongly stick to the surface of glass and iron. Its rust-protection effect is now under experiment.
