| 摘 要： | Unique crystalline morphologies of solution-cast films of HDPE/iPP blends were inves-tigated by means of transmission electron microscopy (TEM), electron diffraction, metalshadowing and specimen-tilt techniques. The unique morphologies come from an epitaxialcrystallization 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 about50°. The HDPE existed with different crystalline morphologies in the two kinds of crystal-line regions of iPP spherulites, i.e. cross-hatched and single-crystal-type structures. Basedon structural analysis, two models of epitaxial growth of HDPE on iPP are proposed.
