Molecular self-assembly is a process where molecules spontaneously organize into specific structures through intermolecular forces such as hydrogen bonding and van der Waals interactions. This method enables the design of nanoscale architectures by varying the volume fractions of the polymer blocks, resulting in nanostructures of different sizes and shapes. In this study, we utilized block copolymer self-assembly to create three-dimensional mesoporous carbon nanocomposites enriched with manganese oxide. The process involved the co-assembly of an amphiphilic PS-b-PEO polymer with manganese and phenol-formaldehyde precursors, leading to the formation of cylindrical structures. Upon carbonization, these structures transformed into mesoporous carbon containing manganese oxide. A range of analytical techniques, including SAXS, SEM, BET, among others, was employed to evaluate the nanostructures. Our findings confirm that these nanocomposites are well-suited as cathode materials for aqueous zinc-ion batteries, demonstrating structural stability and excellent electrochemical performance.
