11.3.2 MATERIALS CHARACTERIZATION
INFRARED SPECTROPHOTOMETRIC ANALYSIS (FTIR)
The IR spectra of gelatin, PAM, and PAM g-gelatin respectively are shown in Figure
6(a–c). From the IR spectra of gelatin, it was evident that it shows a broad absorption
band at 3431 cm
-1
, due to the stretching frequency of the –OH and NH
2
groups. The
band at 2925 cm
-1
is due to C–H stretching vibration. The presence of a strong absorp-
tion band at 1649 cm
-1
confirms the presence of C=O group. The bands around 1446
cm
-1
and 1332 cm
-1
are assigned to CH
2
scissoring and –OH bending vibration, respec-
tively. In the case ...
