5. Conclusions
Preparation of silver nanoparticles via the chemical reduction method of silver nitrate by tri-sodium citrate in an aqueous medium is the best method to synthesis stable alkaline solution of silver nanocolloid. The silver nanocolloid prepared by this method was found to exhibit high stability. Incorporation of alkaline solution of silver nanoparticles into compound to make natural rubber latex foam can enhance the antibacterial activities of the resultant NRLF samples. Moreover, the modified natural rubber latex foam gave anti-fungal properties which were absent in the control NRLF samples. The treated NRLF by SNP can be used as antifungal natural rubber latex foam.
