Characterization and Morphology of Composites Prepared from Polyacrylonitrile and Silver Nitrate

Abstract:

Polyacrylonitrile (PAN)/silver (Ag) nanoparticle composites were prepared via heat treatment of composite solutions of silver nitrate (AgNO3) and PAN in N, N-dimethylformamide (DMF). The resultant composites were characterized by infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and Thermo gravimetric analyses (TGA). TGA results showed that the PAN/Ag composite are thermally more stable than the corresponding neat PAN. XRD results showed that pure phase Ag was obtained in the prepared nanocomposites. They also showed that crystallinity of PAN was largely decreased after the composition with nano-sized Ag. TEM results showed that the Ag particles were in sphere shape with 30-60nm diameter in the as-prepared nanocomposites.
