investigating the effect of cu nanoparticles on the absorption of basic dyes on pan nanofibers

The aim of our research is to investigate the effect of copper nanoparticles in polyacrylonitrile (pan) nanofibers on dye absorption. in this regard, three different concentrations of cu nanoparticles were added to the polymer solution, and the samples produced by electrospinning were used to check the amount of basic dyes absorption. according to the sem images, with the increase in the amount of cu nanoparticles in the samples, the diameter of the nanofibers has decreased and the amount of color removal has increased.
