Implication

Experimental analysis reveals iodide ion arrays direct polymer chain orientation in nylon 6 films, indicating a nucleation mechanism driven by unidirectional iodine diffusion.

Key Points

Investigate the arrangement of iodide ion species within iodinated nylon 6 complexes and determine how iodine penetration induces polymer chain orientation in nylon films.
Treated unoriented amorphous and α-crystalline nylon 6 films with an aqueous iodine–potassium iodide solution.
Examined the spatial alignment of I3− and I5− polyiodide species in uniaxially drawn and planar nylon 6 films.
Desorbed iodine to track the orientation of nylon chains in the resulting γ crystalline phase and during the subsequent γ-to-α phase transition.
Detected two polyiodide species, showing I5− arrays aligned parallel to nylon chains while I3− ions oriented perpendicular to the chain axis.
Treatment of unoriented films aligned I3− parallel and I2/I3− units normal to the film surface, producing perpendicular chain alignment in the desorbed γ form.
Demonstrated that the perpendicular chain orientation persists during the γ-to-α transition, driven by unidirectional iodide diffusion acting as a nucleation template.
