Abstract:A simple and effective approach to induce hierarchical self‐assembly of Y‐shaped amphiphilic triblock polyurethane/poly(acrylic acid) complexes system in aqueous media is reported here. Hydrogen bonding interactions and electrostatic repulsive forces, which can be controlled by regulating the pH condition of complexes solution, were the main driving forces to induce morphological transitions. With the gradual decrease of pH value, a variety of micro‐/nanostructures including giant vesicles, small vesicles, mul… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
