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

Abstract

In here, chemical oxidative synthesis of a new poly(quinoline)-copper composite was given in one-step pathway. To obtain composite, the copper sulphate 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 solid state conductivity measurements. SEM observations exhibited the presence of a plate-like heterogeneous morphology. Rod like structures was revealed from TEM images. TEM studies also indicated that the copper nanoparticles were almost uniformly distributed on polymer. The thermal decomposition kinetics of oxidation product were also studied. For this, the different methods such as Coats-Redfern, Flynn-Wall-Ozawa, Tang and Kissinger-Akahira-Sunose were used.
