چكيده فارسي :
In this study, the effects of incorporating Fe3O4 nanoparticles on the hydrogen bonding index, degree of crystallinity and shape memory behavior of polyurethane (PU) nanocomposites were studied.PU/Fe3O4 nanocomposites were prepared by solution casting method. The degree of crystallinity of the samples was determined using differential scanning calorimetry (DSC). The results of the shape memory test revealed that the increment of the degree of crystallinity improved the shape fixation ratio of temperory shape of PU/ Fe3O4 nanocomposites.
