Main Methods:
- Employed a template synthesis strategy combining polymerization-induced self-assembly (PISA) and oxidative polymerization.
- Utilized RAFT-mediated PISA to create morphology precursors (PTN-templates) by controlling composition, hydrophilic segment charge, and solids content.
- Investigated morphology retention, polythiophene chain formation, and spectral shifts (UV-vis, fluorescence) to confirm PTNP synthesis.
Main Results:
- Achieved a wide variety of PTN-templates with diverse morphologies by systematically regulating PISA parameters.
- Successfully synthesized PTNPs exhibiting morphology retention from the prepared templates.
