Vesicles prepared in water from a series of diblock copolymers “polymersomes” are physically characterized and compared to lipid vesicles. With increasing molecular weight M̄n, the hydrophobic core thickness d for the self-assembled bilayers of poly(ethylene oxide)-polybutadiene (PEO-PBD) increases up to ≃20 nm considerably greater than any previously studied lipid system. The mechanical responses of these membranes, specifically, the area elastic modulus Ka and maximal areal strain αc are… CONTINUE READING
