Synthesis and characterization of polyaniline/magnetite nanocomposites for fabrication of nanofiber textile

Polymers nanocomposites containing inorganic fillers like metal particles dispersed in the polymer matrix are of great interest for the optical and dielectric application. Polymer/inorganic composites such as polyaniline/magnetite nanocomposites (PAni/Fe3O4) can be manipulated through various treatm...
