The films were prepared by mixing all solutions until homogeneous before pouring into<br>polystyrene plates and dried in an oven at 40 o<br>C for 3 days. The obtained films were characterized for their<br>morphology and secondary structure using scanning electron microscope (SEM) and Fourier transform-infrared<br>(FT-IR) spectrophotometer. The native keratin film had smooth surfaces with slight fragile throughout the film<br>area. Considering among the cross-linked agent, the keratin film cross-linked with glutaraldehyde had the<br>smoothest surfaces than others. In addition, the differences of cross-linked agents were affected on different<br>morphology of the films. The secondary structure analysis found that random coil structures of films had been<br>changed into β-sheet after blending with cross-linked agent. This reflected to increase of dense texture, strength<br>and thermal stability of the films. The results could be suggested that the morphology, secondary structure and<br>thermal stability of the keratin films were depended on content and type of cross-linked agents used.<br><br></p> ER -
