Preparation of Ag–Polyacrylamide Nanocomposites by Ultraviolet Irradiation Technique
Polyacrylamide (PAM)/silver (Ag) nanoparticle composites were prepared via ultraviolet irradiation of a mixture solution of silver nitrate (AgNO3) and PAM. The resultant composites were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) thermogravimetric (TG) and Fourier transform infrared (FT-IR). XRD results showed that pure phase Ag was obtained in the prepared nanocomposites. TEM results showed that the Ag particles were in sphere shape with 8-25nm diameter in the as-prepared nanocomposites. FTIR characterized the interaction between polymer chains and Ag particles in hybrid nanocomposites. The TGA results showed improved thermoresistance and high thermal stability behavior of hybrid composites.
