Summary
Carboxylic ended aryl-alkyl hyperbranched polyester poly(5-hydroxyethoxyisophthalic acid) (PHEIA) was synthesized and employed for an electrostatic layer-by-layer self-assembly procedure, in which poly(diallydimethylammonium chloride) (PDAC) was used as the polyanion while PHEIA acted as the polycation. From both aqueous solution and water-THF mixture of PHEIA, self-assembly films have been successfully formed as monitored by UV-Vis spectroscopy and contact angle measuring device. In the self-assembled surface where PHEIA acted as outmost layer, sphere-like particles with uniform diameter was observed by Atom Force Microscope (AFM). This phenomenon should be attributed to the aggregation of PHEIA. Furthermore, the layer-by-layer self-assembly procedure provided a favorable method for adjusting the hydrophilicity of the substrate without much interpenetration between these two polyelectrolyte layers.
