Formation of polymer vesicles by liquid crystal amphiphilic block copolymers.

摘要: We report the formation of polymer vesicles (or polymersomes) by a new class amphiphilic block copolymers in which hydrophobic is side-on nematic liquid crystal polymer. Two series these copolymers, named PEG-b-PA444 and PEG-b-PMAazo444, with different hydrophilic/hydrophobic ratios were synthesized characterized detail. Polymersomes nanotubes formed adding water into solution dioxane. finally obtained dialyzing resulting mixture against water. These self-assemblies have been studied classical TEM cryo-TEM. For series, polymersomes observed for ranging from 40/60 to 19/81. PEG-b-PMAazo444 26/74 18/82. sample ratio equal 25/75, tubular morphology tube diameter typically 100 nm length up 10 mum was also together during addition
