Abstract
Description
We report a laboratory developed efficient metal rotating collector design in electrospinning that aligns majority of the polyvinyl alcohol nanofibers with or without carbon nanotube inclusions. The average diameter of PVA and PVA-CNT composite nanofibers fabricated is 200 nm. A comparison of fiber diameter distribution and alignment has been established in case of static and laboratory designed rotating disc collector. Raman analysis suggests the presence of carbon nanotubes in the electrospun web. AFM suggests the thinness of the fibrous filaments and SEM shows the structural morphology of the fibers.
