Abstract

Effects of the isothermal crystallization temperatures of poly(vinylidene fluoride), T(IC,PVDF), on polymorphic crystalline structure, phase transition, fractional crystallization, and enzymatic degradation of poly(butylene adipate) (PBA) in crystalline/crystalline blends have been investigated. The crystal modifications of PBA can be regulated by T(IC,PVDF). Lower T(IC,PVDF) (e.g., 80 °C) facilitates the formation of PBA α crystals in both the isothermal and nonisothermal melt crystallizations and also favors the β-to-α phase transition of PBA upon annealing at elevated temperatures. This might be attributable to the decreased equilibrium melting temperature of PBA when T(IC,PVDF) is decreased. Higher T(IC,PVDF) is favorable for the fractional crystallization of PBA, which tends to segregate in the interlamellar regions of the PVDF matrix under these conditions. PBA shows faster enzymatic degradation in the blends with a lower T(IC,PVDF) than those with a higher T(IC,PVDF), attributable to the preferential formation of α crystals at a lower T(IC,PVDF). This study provides a new method to control the crystal modification and physical properties of polymorphic polymers in their blend systems.

  • There are few binary miscible blends showing fractionated crystallization, such as PEO/PBS, PBA/PVDF, PBA/PBS, PEO/PHB, and PEO/PES.

    “Compared to immiscible blends, there are just few binary miscible blends showing fractionated crystallization, such as PEO/poly(butylene succinate) (PBS) [69][70][71][72][73] , poly(butylene adipate) (PBA)/poly(vinylidene fluoride) (PVDF) [ 74 , 75 ], PBA/PBS [76] , PEO/poly(3-hydroxybutyrate) (PHB) [77][78][79][80] , PEO/ Poly(ethylene suberate) (PES) [81] .”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
