Presumably, the shifting of the hydrogen-bonded N-H, C=O, and O-H stretching bands into higher frequencies and the decrease in [DELTA][nu] can be attributed to the gradually weakened hydrogen bonds between the amide/carbonyl groups and hydroxyl groups present in the PA6 and PVA molecules, respectively, and hence, cause the absorption band of the free amide, carbonyl, and hydroxyl groups to become more pronounced.
