MICRO-FTIR STUDIES ON THE LARGE STRAIN DEFORMATION AND FAILURE OF SEMI-CRYSTALLINE POLYMERS
Understanding of the structural evolutions during deformation and failure is critical for preparation of high performance polymers and extensive efforts are still undergoing in polymer community. Due to the presence of two phases, actually, the structural evolutions in the semi-crystalline polymers under stretching are complicated. More and more studies have suggested that the deformation and failure at large strain is taken over by the amorphous entangled network rather than by the crystalline phase.1 In this context, Fourier transform infrared spectroscopy is advantageous in monitoring the molecular orientation in the amorphous phase over other methods. Moreover, because of inhomogeneous deformation in the necking region and at crack tips a micro-sampling technique is required.
