ATR-FTIR spectra of the a pristine PCL, b PCL-NH2 from 1 h of aminolysis, c PCL-gelatin, d pure gelatin. The successful immobilization of gelatin was deduced from the presence of a broad band of free O–H and N–H groups (at 3,295 cm−1), amide I band (at 1,650 cm−1) and amide II band (at 1,550 cm−1) as compared to the FTIR spectrum of pure gelatin
