Synthesis and Characterization and Thermal Decomposition Kinetics of Poly (quinoline)-Copper Composite

Abstract

In here, chemical oxidative synthesis of a new poly(quinoline)-coppercomposite was given in one-step pathway. To obtain composite, the coppersulphate and 2-amino-8-quinolinol were used as oxidant and monomer,respectively. The oxidation product obtained was characterized by FTIR, UV-Vis,thermogravimetry (TG), photoluminescence (PL), SEM-EDX, TEM analysis and solidstate conductivity measurements. SEM observations exhibited the presence of a plate-like heterogeneousmorphology. Rod like structures was revealed from TEM images. TEM studies also indicated that the coppernanoparticles were almost uniformly distributed on polymer. The thermaldecomposition kinetics of oxidation product were also studied. For this, the differentmethods such as Coats-Redfern, Flynn-Wall-Ozawa, Tang and Kissinger-Akahira-Sunose were used.
