  • Exfoliative Mg/Al layered double hydroxide (Mg/Al-LDHGly) was obtained via hydrothermal synthesis in the presence of glycine. The product prepared by hydrothermal reaction for 10 h at 120 ℃ possesses high thermal stability and maximal crystallite size in a, c directions. TEM and SEM analyses show that Mg/AlLDHGly was of well-crystallized hexagonal product with stacks of slightly curved layers. Benefiting from mechanism investigation on its gradual delamination in formamide, rapid delamination of Mg/Al-LDHGly at room temperature was realized, which provided fundamental for preparation of (Mg/Al-LDHGly)/polymer nanocomposites by using exfoliation-adsorption method.

Abstract: Exfoliative Mg/Al layered double hydroxide (Mg/Al-LDHGly) was obtained via hydrothermal synthesis in the presence of glycine. The product prepared by hydrothermal reaction for 10 h at 120 ℃ possesses high thermal stability and maximal crystallite size in a, c directions. TEM and SEM analyses show that Mg/AlLDHGly was of well-crystallized hexagonal product with stacks of slightly curved layers. Benefiting from mechanism investigation on its gradual delamination in formamide, rapid delamination of Mg/Al-LDHGly at room temperature was realized, which provided fundamental for preparation of (Mg/Al-LDHGly)/polymer nanocomposites by using exfoliation-adsorption method.
