Self-Assembly Ultrathin Films Based On Dendrimers

Abstract

Abstract: An ultrathin film with forth generation poly(aminoamine)(PAMAM) dendrimers (methyl quaternary ammonium salt) as polycation and poly(sodium p styrenesulfonate) (PSS) as polyainon was fabricated via sequential deposition. It shows that the step by step depositions carried out smoothly by monitoring with UV Vis spectrometer. The multilayer film is rather flat with a mean roughness of 0.39 nm determined by AFM. The average thickness of a bilayer is 5.0 nm obtained from XRD, which indicates that the dendrimers molecules were compressed and possess high flattening.

Key words: Dendrimer, Self assembly, Electrostatic interaction
