In this study, the novel Locust Gum/polyethylene glycol-silver nanoparticles (LG/PEG-Ag NPs) were prepared using a green and facile ultrasonic method. Also, this study highlighted the effect of ultrasonic cavitation on morphological and structural of the biopolymer blend based nanostructure. The ultrasonic-dependent rheological properties of LG/PEG-Ag NPs were investigated, and mathematical models were constructed with the results of viscosity studies using the dilute solution viscometer (DSV) method. The LG/PEG-Ag NPs were characterized by different techniques such as Fourier Transform-Infrared Spectroscopy (FTIR), Scanning Electron Microscopy / Energy Dispersive X-Ray Spectroscopy (SEM/EDX), and Brunauer–Emmett–Teller (BET). According to the results, LG/PEG-Ag NPs exhibited a uniform spherical shape with a diameter of 320 nm while the surface area was 130.533 m2/g. The influences of the operating parameters such as the sonication time, amplitude, salt, and temperature on the intrinsic viscosity of fabricated LG/PEG-Ag NPs was examined in different experimental conditions to optimize the system. Additionally, the optimization on the effect of the rheological parameters of the LG/PEG-Ag NPs with the highest correlation constant was determined using the Huggins model. The experimental results provided a mathematical model to describe the effect of the LG/PEG-Ag NPs on the intrinsic viscosity for nanofluids. Finally, comparative error analysis models were conducted to verify the validity of the obtained relationships.
