Imidazole-functionalized nitrogen-rich Mg-Al-CO3 layered double hydroxide for developing highly crosslinkable epoxy with high thermal and mechanical properties

Ionic liquid-based N-octadecyl-N'-octadecyl imidazolium iodide functionalized layered double hydroxide (LDH-IM) was synthesized for manufacturing high-performance epoxy nanocomposites. Nonisothermal differential scanning calorimetry (DSC) performed to study cure kinetics of reinforced قث with LDH and LDH-IM. Incorporation Mg-Al-CO3 into hindered the curing reaction, as detected by dimensionless Cure Index (CI). By contrast, epoxy/LDH-IM cured Good Excellent due ionic liquid. Higher activation energy completely nanocomposite obtained compared epoxy/LDH The reaction rate calculation orders instantaneous autocatalytic non-catalytic reactions, optimal kinetic parameters based on isoconversional methods were in good agreement experimental rates. Lower value Tg neat signified weak interactions between Mg-Al-CO3-LDH matrix, while a higher epoxy/LDH-IM. Network degradation samples also investigated. decomposition approved strong interfacial adhesion assigned system. highly reactive nature developed LDH-IM gives reason its usage developing curable high thermal mechanical properties.
