摘要: In this study, we report a new phenomenon dealing with the size-dependent behavior of wall thickness block copolymer vesicles, especially decrease in decreasing vesicle size. Four vesicle-forming copolymers from polystyrene-b-poly-(acrylic acid) (PS-b-PAA) family (i.e., PS(500)-b-PAA(50), PS(310)-b-PAA(28), PS(240)-b-PAA(15), and PS(412)-b-PAA(46)) were chosen for study. The sizes thicknesses vesicles after quenching determined TEM micrographs, plots made versus size each various blocks. First, effect length PAA on relationship between was examined. prepared longest that yields smallest decreases strongly By contrast, case which ...
