This experiment demonstrates that PANI is grafted onto chitosan chain. It is worth remaining that the experimental procedure ensures the removing of free PANI.
Moreover, the degree of substitution of the chitosan amino group seems to be relatively small based on the fact that the peak assigned to this monosubstituted unit (at 4.94 ppm) is included within the H-1 signal (at 4.80 ppm). Moreover, it cannot be
calculated from the integral of the signal assigned to protonated amine group of PANI due to the fact the ratio of ionized groups is hardly known,even if it should theoretically be 50 mol%. Under these considerations, we assume that few long chains
of PANI are grafted onto the chitosan backbone based on the small degree of substitution and the quantity of grafted PANI

The assignment of this triplet is confirmed by its disappear-
ance when D2O was added (resulting of an exchange of proton by deuterium)
