【 摘 要 】

In the present work we have synthesised PVP composite nanofiber by using the electrospinning technique. The development, and morphology of the readied nanofibers were analysed by SEM. Arrangement of ultra-fine consistent smooth fibers with diameter across in the scope of 64-116 nm and length up to a few microns was seen in the case of PVP composite nanofibers. Experimental investigation was performed by electrospinning of PVP considering 6grams dissolved in 40ml Di-MethylFormamide(DMF).The process parameters considered were voltage of 20kV, flow rate 0.5ml/hr, needle dimension 21 gauge and tip-to-collector distance 100 mm. It was found that concentration of polymer is a critical factor in controlling the beads formation and fiber diameters although applied voltage and Spinneret to-collector distance also influenced the fiber diameter.
