Abstract

This work aims to fabricate natural rubber composite with an antimicrobial performance by incorporating silver nanoparticles (AgNPs). The AgNPs were in-situ synthesized by serving AgNO3precursor in natural rubber latex without reducing agent. The result finds the typical yellowish-brown slurry and shows the surface plasmon resonance (SPR) absorption band between 350-650 nm wavelength, revealing the formation of AgNPs in the natural rubber latex. TEM images display the spherical shape of AgNPs with the size between 5-30 nm. The negative value of zeta potential (-56.7 mV) elucidates more stability of AgNPs suspended in natural rubber latex. The as-prepared natural rubber latex containing AgNPs was utilized to fabricate rubber composite. The tensile test reveals the slight decline in mechanical strength; meanwhile, strain at break of rubber composites containing AgNPs does not significantly changed when compared to rubber composite without AgNPs. The clear inhibition zone suggests an antimicrobial manner of rubber composite containing AgNPs against E. coli and S. aureus pathogens. This result indicates that AgNPs are the responsible element for rubber composites' antibacterial property. This work substantiates the successful synthesis of AgNPs with a green and cost-effective procedure without utilizing a reducing agent. Moreover, it raises the natural rubber composite with antibacterial performance, which could be widespread end-use applications of natural rubber.
