Synthesis and characterization of polyaniline-polyanethole composites as conductive polymer materials

Abstract

Synthesis of polyaniline-polyanethole (PANI-PAN) composite has been successfully carried out by mixing method at room temperature using dichloromethane as solvent. PANI-PAN composites were reacted at 5%, 10%, and 15% polyanethole variations by weight of polyaniline. The synthesis results obtained were structure analyzed by FTIR and characterized by TGA, SEM-EDX, and conductivity. The synthesis of PANI-PAN composites from various variations resulted in the product being a grayish green solid. The success of the PANI-PAN composite synthesis was shown by the results of the FTIR analysis, namely the presence of a typical absorption between polyaniline and polyanethole in the PANI-PAN 5, 10, 15% (w/w) composite, respectively, is indicated by the presence of an amine group (-NH-) at a wavelengths of 3499.94 cm-1, 3457.55 cm-1, and 3506.74 cm-1 for polyaniline and ether groups (C-O-C) at wavelengths 1235.46 cm-1, 1244.14 cm-1, and 1242.21 cm-1 for polyanethole. The morphology of the PANI-PAN composite was performed using SEM-EDX showed the presence of cavity filling in the polyaniline indicated that there had been an even distribution between the polyanethole in the polyaniline. The results of thermal analysis showed an increase in thermal stability compared to polyaniline. The conductivity value of the PANI-PAN composite showed a better value than polyaniline and was optimal at 10 wt% variation.
