dc.description.abstract | In this study, we investigated the effects of mesoporous titanium silicate (TS-1) zeolite on the melting behavior and isothermal crystallization in poly(butylene succinate) (PBS)/TS-1 zeolite hybrid composites (PTHC). Isothermal crystallization results revealed that TS-1 zeolite acted as a nucleation agent in PTHC, thus the t (1/2) of PTHC was faster than that of homo-PBS. However, the nucleation effect of TS-1zeolite did not depend on the TS-1 zeolite content. The large surface area of the mesoporous structure readily formed molecular chains inside and outside of the pore mouths of TS-1 zeolite, covering the nucleation site, as a result of the byproduct deposition during polymerization. At isothermal crystallization, temperatures ranging from 88 to 92 A degrees C, nucleation of TS-1 zeolite occurred because of the presence of free byproducts and the formation of a molecular chain in the pore mouths. In contrast, isothermal temperatures ranging from 80 to 84 A degrees C resulted in ineffective nucleus activation because of the steric hindrance in the porous structure. Synchrotron small-angle X-ray scattering (SAXS) analysis revealed that TS-1 zeolite can accelerate lamellar recrystallization during heating. | en_US |
dc.description.sponsorship | rous structure of TS-1 zeolite on the crystallization andmelting behavior of PTHC samples by isothermal crystallizationand SAXS analyses. TS-1 zeolite exhibited differentnucleus activations at each selected isothermal temperature.This result is due to byproduct deposition inside and outsideof pore mouths in TS-1 zeolite during polymerization.Nucleus activation of TS-1 zeolite in the bulk PTHC systemwas affected by the degree of freedom of the molecularchain in the pore mouths according to crystallization temperature.From SAXS analysis, TS-1 zeolite accelerated lamellarrecrystallization of PTHC samples, compared with homoPBS,during heating. This result could indicate that mesoporousTS-1 zeolite can effectively induce nucleus activationduring melting because the active nucleation sites were notcovered with byproduct. | en_US |
