Pluronic and Poly(acrylamide) based semi IPN hydrogels were prepared by free radical polymerization with redox initiator system in the presence of N,N’-methylenebisacrylamide. Highly stable and uniformly distributed silver nanoparticles have been obtained with hydrogel networks as nanoreactors via in situ reduction of silver nitrate (AgNO3) using sodium borohydride (NaBH4) as reducing agent. The formation of silver nanoparticles has been confirmed with ultraviolet visible (UVvis) spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) analyses, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Thermogravimetric analysis (TGA) provides the amounts of silver nanoparticles exist in the hydrogel networks. The developed semi-IPN hydrogelsilver nanocomposite was evaluated for preliminary antibacterial applications. |
