Abstract
A new generation of polyimide (PI)/silver nanowires nanocomposites were prepared by a solution mixing method with different contents of prepared silver nanowires. The structural and properties of pure PI and PI/Ag nanocomposites were studied by several techniques such as fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy, field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), X-ray diffraction (XRD), electrochemical impedance spectroscopy, and thermal analyses. FT-IR and 1H-NMR spectra confirmed the success in preparation of PI sample. The FE-SEM and AFM analyses show the good dispersion of silver nanostructure in the PI matrix. The XRD pattern shows the presence of crystalline nature of inorganic silver nanowires in the organic amorphous PI matrix. The thermal and impedance spectroscopy analyses results reveal that, with increases in the content of silver in PI matrix up to the 2 vol%, the conductivity, and thermally stability factors of samples were increased.
