Summary: In this study, a quick, easy, effective, and green method for preparing green nanofluids containing silver nanoparticles was introduced for the first time. The solution plasma method with a high-voltage DC power source and extracts from the Paramignya trimera was utilized to prepare spherical silver nanoparticles with an average size of approximately 8 nm, which were uniformly dispersed in solution. The prepared nanofluids exhibited high thermal conductivity, with a maximum improvement of 18.3% obtained for the nanofluid prepared using a 4-minute preparation time compared to the base fluid. These results demonstrate the potential for this simple and environmentally friendly method in producing nanofluids with high thermal conductivity for various applications.
