Graphene-alumina nanostructured hybrid: synthesis with use dodecylamine and physicochemical properties: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 29, No 6


Mixture of sol–gel and sonochemical methods is usually recommended for producing a nanostructured graphene–alumina hybrid, which is a promising uncooked materials for manufacturing fine-grained ceramics. This research focuses on the usage of dodecylamine each within the sol–gel synthesis of Al-containing particles and in sonochemical graphene exfoliation. It has been proven that, when forming graphene–alumina composite in a response combination of Al-containing sol and graphene suspension, graphene sheets participate as a template within the formation of a hybrid construction. Graphene sheets orient sol particles on their floor because of van der Waals interplay and management development and course of oligomeric gel chains. The graphene sheets restrict the expansion of Al-containing particles, which results in a rise within the particular floor of the hybrid as in comparison with an alumina powder sourced from the identical sol. The proposed method allows the preparation of chemically homogeneous composite nanopowders with uniform distribution of parts.
