Resumo |
Unique crystalline morphologies of solution-cast films of HDPE/iPP blends were investigated by means of transmission electron microscopy (TEM), electron diffraction, metal shadowing and specimen-tilt techniques. The unique morphologies come from an epitaxial crystallization of HDPE on iPP. The contact planes of the two kinds of crystals are (100) of HDPE and (010) of iPP, while the intercrossing angle between their chain axes is about 50-degrees. The HDPE existed with different crystalline morphologies in the two kinds of crystalline regions of iPP spherulites, i.e. cross-hatched and single-crystal-type structures. Based on structural analysis, two models of epitaxial growth of HDPE on iPP are proposed. |
