Gamma Irradiation in Grafted Ag-NPs Synthesis to PP Surfaces and DI Water System Modification in Semiconductor Patterning

Abstract

The application of gamma irradiation as a factor to graft the synthesized silver nanoparticles to the polypropylene surface and modify the de-ionized (DI) water supply system is a new experimental project. In this study, using the effect of gamma irradiation on the surface of a certain type of filter, reduces silver ions and modifies the filter surface simultaneously. Then, the effect of the modified filter on the performance of DI water supply systems, which are directly and indirectly related to quantum technologies and nuclear science, was investigated by modeling on the surface of indium phosphide (InP) semiconductor. The dose of gamma irradiation and the reduction conditions of silver nanoparticles were determined after passing the optimization stage. So, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), ultraviolet-visible absorption spectroscopy (UV-Vis), attenuated total reflection (ATR) and bacterial counting tests by plate count agar (PCA) were used. Then it was found that the desired result of filter surface modification is due to the formation of surface plasmon resonance in the colloidal solution of silver nanoparticles which is produced during gamma irradiation synthesis.
