Decoupling particle size and charge transport in PEDOT:PSS via morphological inheritance of monomer emulsification

= 1.06 nm). Grazing-incidence wide-angle X-ray scattering (GIWAXS) reveals the underlying crystallization mechanism: nanoconfined templates generated by extreme cavitational shear force the PEDOT chains to overcome conformational disorder, adopting a highly extended and ordered arrangement. This confinement effect unexpectedly extends the crystal coherence length (CCL) to 12.35 Å. By enhancing charge delocalization within the crystalline domains, this microscopic ordering fundamentally compensates for the transport resistance induced by grain boundary accumulation. Furthermore, the HPH nanocolloids exhibit excellent fluid processing stability (viscosity of 12 mPa s), and their ultrahigh specific surface area endows the films with outstanding interfacial electrochemical capacitance. Ultimately, this work establishes a paradigm in which "microscopic ordering compensates for macroscopic defects," providing crucial physicochemical criteria for the rational design of high-performance conducting polymers.
