WebWe observed morphological changes of the polymer films when the pre-annealing temperature was near the crystalline temperature (Tc, 207°C). These nanostructural transformations resulted in a modified interfacial morphology of the donor phases and, therefore, greatly influenced the device performance.

WebCombined effects of graphene nanosheets (GNSs) and shear flow on the crystallization behavior of isotactic polypropylene (iPP) were investigated by in-situ synchrotron wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS) techniques. For crystallization under quiescent condition (at 145 °C), the half-crystallization time (t1/2) of … WebIn Crystallization of Polymers, 2nd Edition, Leo Mandelkern provides a self-contained, comprehensive, and up-to-date treatment of polymer crystallization.

WebDec 1, 2000 · In addition, the present simulations offer an explanation of the recently claimed “spinodal mode” of polymer crystallization without invoking spinodal decomposition. 2. Simulation method. The simulation model attempts to incorporate just enough detail to observe chain-folding without impeding the efficiency of the simulation. Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by differe… WebThe β-nucleating agent (β-NA), zinc phthalate (ZnPht), was prepared from a mixture of zinc oxide (ZnO) and phthalic anhydride (Pht) during the extrusion of isotactic polypropylene … the outsiders series hulu
