In the field of materials science, one current challenges is to organize nanoparticles with various sizes, geometries and compositions into specific structures for constructing functional devices. this research, self-assembly monotailed single-chain different charge densities was investigated. Poly(2-(dimethylamino)ethyl methacrylate)-block-polystyrene (PDMAEMA-b-PS) synthesized by reversible addition–fragmentation chain transfer polymerization, amphiphilic PDMAEMA were prepared intramolecular cross-linking blocks. The degree controlled at about 20%. surface on reactions varying amounts iodomethane. density has a significant influence nanoparticles. made from PDMAEMA74-b-PS100 self-assemble spherical micelles in aqueous solutions, average size increases density. With an increase density, morphology aggregates self-assembled changes vesicles, mixture worm-like cylinders vesicles. cyclohexane–THF mixture, PDMAEMA74-b-PS297 bunchy micelles, or vesicles large compound depending densities.
