  • Development of a morphology diagram based on composition and molecular weight.
  • Macroscopic alignment of block copolymer films followed by selective degradation of PLA to form nanoporous structures.
  • Structural and surface characterization using small-angle X-ray scattering, SEM, DSC, and N2 adsorption measurements.

    • Main Results:

    • Formation of hexagonally packed nanocylinders of PLA within a PS matrix was achieved.
    • Anisotropic nanoporous polystyrene monoliths with continuous, hexagonally close-packed nanoscopic channels were successfully prepared.
    • Pore size was tunable through synthesis or blending, and channels were lined with hydroxyl functional groups.
    • High surface area and well-defined pore size distributions were confirmed.

    Conclusions:

    • PS-PLA block copolymers are effective precursors for creating aligned nanoporous polystyrene monoliths.
    • The developed method allows for tunable pore sizes and functionalized channel surfaces.
    • These nanoporous materials exhibit significant potential for applications in nanomaterial synthesis, catalysis, and separations.
