Predicting the mechanical properties of animal glue thin films

This report shows that animal glue from porcine skins can be used to make thin films with reproducible properties. It shows that the tensile strength of the film relates linearly to the bloom strength, while the stiffness remains constant for temperatures lower than the glass transition temperature. The report continues to show how Differential Scanning Calorimetry (DSC), Fourier Infra-red Spectroscopy (FTIR), and X-ray Diffraction (XRD) can be used to predict the strength of an animal glue film. The test results show that XRD is the easiest method to obtain a reasonable prediction of the mechanical properties. Meanwhile, DSC holds additional information on the internal stress state of the sample, which may promise better predictions of the mechanical properties once the analysis has been optimized.
