Summary: In this study, a Ni(OH)(2)/CNT/CF composite electrode was developed and characterized to investigate its electrode kinetics for enhanced urea oxidation reaction (UOR) performance. The electrode exhibited satisfactory UOR performance with higher oxidation current and lower overpotential, attributed to the active and reversible Ni2+/Ni3+ redox reaction of the composite. The inclusion of CNTs in the electrode structure led to increased reaction surface area and electrical conductivity, resulting in lower charge transfer resistance compared to conventional electrodes.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
