Abstract
AbstractThe Unidrive X1000 CAT mixer was used to disperse nano‐silver into matrix resin. The field emission scanning electron micrograph showed the flock of nano‐silver has burst into smaller clusters and dispersed evenly in epoxidized rubber seed oil. Two bacterial strains: gram‐positive bacterial (S. aureus) and gram‐negative bacterial (E. coli) were used to evaluate the antibacterial property of sample. The results showed matrix resin without nano‐silver possessed antibacterial property with both strains. The presence of nano‐silver raised the gram‐positive antibacterial property but reduced gram‐negative antibacterial property of matrix resin. The viscosity of matrix resin containing different nano‐silver contents was unchanged except 100 ppm. Moreover, the presence of nano‐silver has prolonged the and curing time but increased maximum exothermal temperature of emission. In general, the presence of nano‐silver improved strongly in mechanical properties of composite especially nano‐silver content of 20 to 60 ppm.
