Interfacial synthesis, characterization and thermal studies of PANI/MAl2O4 (M = Mg, Zn) nanocomposites

Science and technology of nanoscale materials is enriched by developing new synthetic technology and its applications in various fields. Recent development reviews the combustion method which is an efficient and simple method for the preparation of different materials and their composites. Metal oxide-based polymer nanocomposites have gained much importance due to their special applications. In addition, interfacial polymerization method has gained its importance in the synthesis of composites by eco-friendly system. Nanosized metal aluminates such as MgAl2O4 and ZnAl2O4 were prepared by a combustion route using poly(vinyl alcohol) as a fuel. Interfacial polymerization method was used for the preparation of polyaniline-MAl2O4 (PANI/MgAl2O4, PANI/ZnAl2O4) nanocomposites. These composites were well characterized for their structures by employing X-ray diffraction tool and morphology by scanning electron micrograph tool, respectively. In-depth morphology of the sample was well studied by transmission electron micrograph tool. The bonding nature of the sample was studied by Fourier transform infrared (FT-IR) study, and the presence of metals in the composites was confirmed by EDX pattern. Electrical and thermal studies of the PANI/MAl2O4 composites were conducted to understand their electrical and thermal behaviors, respectively. UV-visible and DLS studies of the prepared nanocomposite were also conducted to understand the absorbance and particle distribution, respectively.
