Synthesis and Characterization of Nano-Silver Incorporated Natural Rubber Latex Foam

Abstract

Synthesis and characterization of silver nanoparticles (SNP) incorporated natural rubber latex foam (NRLF) is described. SNP synthesized by reducing of Silver Nitrate (AgNO₃) with Tri-Sodium Citrate (TSC) were adsorbed in-situ on to the NRLF matrix. Antimicrobial activities were tested by qualitatively and quantitatively against Gram positive Staphylococcus aureus and Gram negative Escherichia coli. It was found that the resultant NRLF samples inhibit the growth of so called two main groups of bacteria in very strong manner. The SEM and EDX analysis provided evidence of adsorbed silver particles on the foam rubber matrix are in nanometer size.
