- Аннотация: Polymerization-induced self-assembly (PISA) enables the fabrication of polymeric nano-objects with tunable morphology and surface functionality. To obtain diverse nanostructured morphologies with antioxidant gallol pendants, a gallol methacrylate homopolymer (PM12) was synthesized as a steric stabilizer and subsequently chain-extended with N-phenylmethacrylamide (NP) to yield PM12-b-PNPm diblock copolymers via reversible addition–fragmentation chain transfer dispersion polymerization (RAFTDP) in alcoholic media. Depending on the block length of the PNPm segment, an array of morphologies, including micelles, worm-like aggregates, and vesicles, was obtained, as characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM). The experimentally observed morphology evolution was supported by molecular dynamics (MD) simulations using two complementary approaches: (i) atomistic MD to probe the local conformations of PM12-b-PNPm and its aggregation-driving block, and (ii) coarse-grained MD to investigate aggregate morphologies, thereby providing deeper insight into polymer self-assembly. Furthermore, deprotection of gallol methoxy (–OCH3) groups produced hydroxyl (–OH)-rich shells, endowing the polymers with antioxidant functionality, as confirmed by 1,1-diphenyl-2-picrylhydrazyl (DPPHradical dot) and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTSradical dot+) assays.
