Key Points

To develop a single-reactor hybrid emulsion-dispersion (HED) polymerization strategy for synthesizing functional polymeric Janus nanoparticles without multistep seeded or templated routes.
Induced symmetry breaking via polymerization-induced phase separation in a single-pot reactor without seed preparation, sequential monomer addition, or post-modification.
Conducted kinetic analyses and constructed a morphology map to evaluate the effects of solubility, interfacial energy, and kinetic arrest on particle architecture.
Synthesized N-halamine-functional Janus nanoparticles (<200 nm) and evaluated their interfacial enrichment and antibacterial efficacy in coating systems.
Polymerization-induced phase separation established symmetry breaking within the first minutes of the reaction, successfully generating sub-200 nm Janus nanoparticles.
Particle composition and morphology were tunable by controlling the balance between polymer solubility, interfacial energy, and kinetic arrest.
N-halamine-functional Janus nanoparticles preferentially enriched at coating-air interfaces, conferring efficient and rechargeable antibacterial activity.
