Abstract
Natural rubber (NR)-based composites or hybrid products obtained from NR and several nano-materials are of interest due to their wide range of applications. However, they are easily contaminated with bacteria or fungi that can affect human health, especially those used in food container and on human skin. Herein, we present the composite sheets of NR latex and silver nanoparticles (AgNPs) with exceptionally high antibacterial activities. AgNPs were firstly synthesized by a facile, rapid, and green microwave-assisted method using curcumin as a biomaterial reductant and stabilizer. Then, natural rubbers loaded with AgNPs (NR/Ag) composite sheets were prepared via a simple direct latex mixing-casting process of NR latex and various contents of AgNPs. The result demonstrated that the synthesized AgNPs had a spherical-like shape of 12.25 ± 3.13 nm. All the prepared NR/Ag composite sheets exhibited high performance in antibacterial properties against Staphylococcus aureus and Escherichia coli, and the antibacterial activities were dependent on the loaded AgNPs content. In this study, it is anticipated that these rapid, simple, green, and effective methods can suitably be scaled up for large-scale preparation of the stabilized AgNPs colloid and NR/Ag composite products.
