Interfacial bonds between matrix and reinforcement materials are one of the most important parameters in composite materials to improve wettability and stress transfer. In this research, interfacial covalent bonds between alumina and carbon nanotubes (CNTs) were created by microwave treatment of aqueous solution of mixed Al(acac)3 precursor with CNTs. Al(acac)3 precursor was used to decorate Al3+ ions on the CNT surface. Furthermore, microwave treatment was utilized to form Al2OC and Al2O3 composite on the CNT surface. The Al-O-CNT covalent bonds were formed by thermally energetic microwave radiation, which was confirmed by x-ray diffraction and X-ray photoelectron spectroscopy.
