Monomer insertion into vesicle membranes and fixation of monodisperse kinetically stabilised vesicles
The formation of monodisperse vesicles in the system TDMAO (tetradecyldimethylamine oxide) - LiPFOS (lithium perfluorooctylsulfonate) can be finely controlled by the presence of a polymer of the pluronic type (EOn-POm-EOn). Thereby vesicles with a low polydispersity of 5% and controlled size depending on the polymer concentration can be produced, that are sterically stabilised by polymers attached to the vesicle bilayer. In our investigation we aim to use these vesicles as templates to produce well-defined hollow polymer capsules. SANS will be used to determine the location of monomers and resulting polymer (using deuterated compounds) and the effect on the vesicles' structures. From this study valuable information regarding a systematic and optimized formation of such nano-sized polymer capsules shall be gained as they would be interesting for instance as containers for active agents.
