| Abstract | Colloidal silver nanoparticles synthesis (CSNPs) with the chemical reduction method obtained the achievement by using PET oligomers as a stabilizer that was oligomerized from the glycolysis reaction of poly (ethylene terephthalate) (PET) and ethylene glycol (EG). The study was conducted by varying the concentration of silver nitrate (AgNO3) solution, D-glucose, and stabilizer to find the most suitable conditions to control silver nanoparticles (AgNPs) size. Fourier transform infrared spectroscopy (FTIR) exposed oligomers’ functional groups, the same as poly (ethylene terephthalate). The scanning electron microscope (SEM) and atomic force microscopy (AFM) revealed that the smallest size was about 42 nm for high concentration at 0.75 M of AgNO3 solution, 1.00 M of D-glucose, and 1.8%w/w of the PET: EG ratio. When analyzed by an atomic absorption spectrophotometer (AAS), the AgNPs concentration was approximately 71,870 ppm. The antimicrobial efficiency test by the plate count method showed greater than 95% inhibition when using CSNPs at AgNPs concentration of 10 ppm. Furthermore, blending CSNPs in polyethylene pellets and polyethylene sheets at AgNPs concentrations of 200 ppm and 750 ppm, respectively, could provide more than 95% inhibition efficiency. |
