Introduction: The use of processes based on nanomaterials and nanotechnology is growing rapidly in all fields of science and technology, and due to the problems of the dust crisis in the south and southwest of the country and air pollution in metropolitan cities and industrial cities, the production of anti-spandband Bacterial has many uses to reduce contamination and stop the growth of various contaminants (germs, viruses and bacteria).
The present paper has been carried out with the aim of producing antibacterial mask from silver nanofluid by library and experimental method in laboratory environment. The results of this article can help reduce the dust crisis and respiratory problems of patients, especially in metropolitan areas.
Methods: Checking antibacterial tests , halo and using standard and valid cards such as: books, ISI articles, etc.
Results: Observations of the diameter of the halos show that spunbond filters are resistant to standard bacteria, especially at 4000 ppm, and reduce bacterial growth by a large percentage and have the greatest antibiotic effect. The filter with a concentration of 2000 ppm and then a filter with a concentration of 1000 ppm had an antibiotic effect. Also, by examining the quantitative results of antibacterial test by Behprovar Salamat Laboratory and approved by the Food and Drug Administration regarding bacterial growth of a sample with an optimal concentration of 4000 ppm in the vicinity of five different types of standard bacteria shows that the number of bacteria in culture medium adjacent to the sample The coating remained constant and bacterial growth and proliferation did not happen.
Conclusion: Air pollution is one of the most important problems of metropolises and industrial cities that has caused numerous respiratory problems in the people and the presence of fine dust in the south and southwest of Iran has caused respiratory diseases and many problems for the people. The production of antibacterial spunbond masks from silver nanofluids produced in this study, helps a lot to the diseases mentioned, and can be a suitable and cost-effective alternative for these patients. Also, the simple and low-cost coating method with immersion method in this research to produce antibacterial spunbond from silver nanofluid is a suitable alternative to previous time-consuming and cost-effective methods.
