Electrospun polyacrylonitrile nanocomposite fibers reinforced with iron nitrate nanoparticles

The methodology of preparing pure Polyacrylonitrile (PAN) fibers and magnetic PAN/FeNO3 composite Nanofibers is the traditional electrospinning process where fibers of diameter ranging less than 100 nm and larger lengths can be sophisticatedly produced on laboratory bench. With varying properties of polymer concentration, voltage and other parameters pure PAN fibers and those loaded with FeNO3 are produced. Analysis of those prepared fibers has been done through a series of experiments like SEM, FITR and X-ray Diffraction. SEM analysis explains the formation of fibers and leads to the selection of best possible ones for future methods of rheological and TGA analysis. In the past where similar contributions have been done for the fibers with FeO and Fe3O4 and the Nanoparticles, the same mentioned procedure replaces them with FeNO3. On the whole, uniform bead-less fibers are obtained and their behaviors' are studied as well. Also, graphical information for correlating the size of fibers and their polymer concentrations has been obtained. TGA analysis for recording their stability under different thermal conditions is reported. Anilining methods using microwave equipment are done instead of conventional ones.
