Hyperbranched poly(ester-amine) (PEAC) with terminal acrylate groups aggregated into micelles in acidic methanol-water mixed solutions at a volume ratio 1：100．and the micellar size became large with increasing the solution pH value．Self-assembled films were successfully formed from hyperbranched polyester (PMPP) with terminal aromatic carboxylic acid groups and PEAC by layer-by-layer dipping and the process was affected by the pH value of PEAC solutions．With PEAC as the ouflayer

further reaction of the self-assembled film based on acrylate groups was investigated．The film was irradiated by UV light and washed byionizingwater．The cured film fell off the substrate seriously due to the highly branched architecture of PEAC and the polymerization of acryate groups．In addition

the self-assembled film was immersed in aqueous p-phenylenediamine solution for 72h．Regular spherical particles in diameter of 200 nm were observed on the film surface

which was due to the stroag arene-arene interaction of benzene rings introduced into the film surface through Michael addition between acrylate groups and amino groups in p-phenYlenediamine．
