The hydrogen-bonded poly(vinylpyrrolidone)/poly(acrylic acid) (PVPON/PAA) thin films were prepared by the step-wise interfacial complexation, i.e. layer-by-layer assembly process. Rhodamine B (RB), was utilized as mode compounds to investigate the pH

a b s t r a c t Poly(vinylpyrrolidone) (PVPON) and poly(acrylic acid) (PAA) were layer-by-layer (LBL) assembled to prepare the thin films based on hydrogen-bonding complexation. The hydrogen-bonded PVPON/PAA films were incubated in acidic, neutral an
