The study used arc discharge method (ADM) to produce silver nano-colloid in deionised water (DW), and compared the difference between pre-adding and post-adding of polyvinyl alcohol (PVA). First, they added 50 ppm of PVA into 200 mL silver nano-colloid, named Ag-PVA. Second, they added 50 ppm of PVA into 200 mL DW as the dielectrics and produced silver nano-colloid through it, named PVA-Ag. Then they compared the differences between two samples with several instruments. They examined wavelength and absorbance by using UV–visible spectrophotometer (UV–vis), used Zetasizer to measure particle size and zeta potential, adopted scanning electron microscope (SEM) and transmission electron microscope (TEM) to observe shape, size, and distribution of the silver nanoparticles in the colloid. The results indicated that colloid PVA-Ag had higher zeta potential and better suspension.
