Nanoparticles positioning effect on properties of (PS‐PANI/NiNPs) nanocomposite films

This work presents the effect of driven nickel nanoparticles (NiNPs) towards surface (PS-PANI)/NiNPs nanocomposite upon application a uniform magnetic field. The purpose is to obtain distinguishable optoelectronic and electrical properties. process increases roughness its reactivity, enables tuning optical Based on results from X-ray photoelectron Fourier-transform infrared spectroscopies, magnetically-driven NiNPs are oxidized, forming NiONPs NiOHNPs. oxidation transforms hydrophilic hydrophobic state. In addition, bandgap energy decreases 4.04 3.77 eV, conductivity 12.77 μS/cm 57.80 77.52 μS/cm, for 50 100 mT fields, respectively, which attributed well-dispersed in PS-PANI polymer matrix, resulting high homogeneous film.
