Recently, a novel coating method using an aqueous doapmine solution was proposed, the deposited coating was found to have extraordinarily strong-adhesion to numerous materials such as metal and polymers. However, it has suffered from many controversy in scientific fields due to its final structure and deposited mechanisms. Here, we have proposed a new structure for final dopamine product coupling with solid state spectroscopic, thermal behavior, and gas transport behaviors of dopamine coated microporous polyethersulfone membranes. In its final analysis, the results represented that it is a supramolecular aggregated of monomers consisting of 5,6-dihydroxyindoline and its derivative in contrast to previously proposed polymeric structure.
