WitrynaThe studies are concerned with isothermal crystallization at various temperatures (10 to −50°C) and at constant elongation ratios (1–4.5) and hence with the effects of weak-to-intermediate and high orientations on oriented crystallization versus the behavior of unoriented specimens. Witryna17 sty 2024 · It was found that the PCL films with similar thicknesses crystallize much faster on oriented PE than on CaF 2 substrate. For example, the crystallization rate constant of a 102 nm thick PCL film decreases tremendously by 3 orders of magnitude from 1.1×10 −1 on PE substrate at 50 °C to 7×10 −4 on CaF 2 surface at 40 °C.
