Abstract: Carboxylic ended aliphatic aromatic hyperbranched poly(5-hydroxyethoxyisophthalic acid)(PHEIA) was employed for an electrostatic layer-by-layer self assembly procedure. The self-assembly films have been successfully formed from both aqueous solution and water THF mixture. The self assembly procedure was monitored by UV-Vis spectroscopy and contact angle measurement meter. The obtained multilayers were characterized by AFMfor the surface morphology investigation. The results indicate that PHEIAis able to form self assembly film in the presence of poly(diallyldimethylammonium chloride) (PDAC). On the self assembled surface where PHEIAacted as an outmost layer, the PHEIAaggregated into sphere-like particles with uniform diameter. Furthermore, the layer-by-layer self-assembly procedure provided a favorable method for modification of the hydrophilicity of the substrate without heavy interpenetration between these two polyelectrolyte layers.
