Pretreated by Polyethyleneimine and n-tetradecanoic acid adsorption, the super-hydrophobic film was formed on the fresh aluminum surface. 摘要通过聚乙烯亚胺与十四酸的反应，在铝表面构建稳定的超疏水膜。
Plasmids encoding genes for either green fluorescent protein or red fluorescent protein were bound to superparamagnetic nanoparticles coated with polyethyleneimine. 无论是编码绿色荧光蛋白还是红色荧光蛋白的质粒编码基因都是与外包聚乙烯亚胺的超顺磁性氧化铁颗粒结合。
