The orientation and crystallization of poly(ε-caprolactone)/poly(vinyl chloride) (PCL/PVC) blend film, induced by highly oriented polyethylene (PE), have been investigated. One can evidence that PCL can grow orientedly on underlayer PE in its blends with PVC. Moreover, it was revealed that the degree of orientation of the PCL/PVC (50/50 wt%) blend film can continue to increase during annealing process even after the overlayer-oriented PE have been peeled off. This result indicates that a layer of crystal aggregates or only oriented PCL molecules can be initiated by the oriented PE during solvent evaporation process, and these aggregates or oriented molecules can serve as nuclei to induce the following oriented crystallization without induction layer. Moreover, the overlayer PE can induce the blend film to reach higher degree of orientation than PE underlayer can do. This should be attributed to the lower free energy of PCL than that of PVC, and PCL prefers to enrich at the air/polymer interface and can be induced to orient crystallization by PE overlayer than by underlayer PE layer. The result can provide a method to regulate thin films of small organic molecules or conjugated polymers without the alignment layer.
