2. FTIR spectra: (a) the standard spectrum of polyacrylamide obtained from The
Aldrich Library of Infrared Spectra, Edition Ⅲ, No. 18127-2, (b) the spectrum of
poly[N-(2-Aminoethyl)acrylamide], its sample was obtained from the solvent after the
synthetic process was carried out by fully separating the PbS CNWs and evaporating
the small molecules (ethylenediamine, H2O). Compared to (a), a characteristic peak of
-CO-NH-R at 1566 cm-1 appeared in (b) resulting from the combination of the bending
vibration of NH and the stretching vibration of C-N,* which was apparently different
from that of –CO-NH2 [at ~1620 cm-1, δ(NH2)].** The wide peak at 3366-3261 cm-1
resulted from the stretching vibration of NH existing in the structure
–CO-NH-CH2-CH2-NH2. The deformation vibration of the NH2 in -CH2-CH2-NH2
was located at 1615 cm-1, which could not separated from that of the stretching
vibration of C=O (1641.8 cm-1).
