Crystallization and Mechanical Properties of Nano ZnO/PP/PLA Composite Filaments

摘要

In the present work, the effect of plasma treated ZnO nanoparticle on crystallization behavior and properties of polypropylene(PP)/polylactic acid (PLA) composites filaments has been intensively researched. Our results show that, although the interracial interaction between PP/PLA and nano ZnO is very weak, addition of nano ZnO and the proportional relations of PP/PLA in composites induced the increase of percent crystallinity. Tensile results showed that nano ZnO /PP/PLA nanocomposites filaments were strain rate sensitive materials and the activation volumes of the nano ZnO/PP/PLA nanocomposite filaments by following Eyring's equation could be evaluated.
