Abstract
One of the most necessary vitamins for human's body is vitamin E which many scientists investigated on release. In this study, two new compatible polymers (POLYCAPROLACTONE and CHITOSAN) have used at the same time for creating a nanolayer with this vitamin. Two methods of producing including electrospinning and finishing have studied. For this purpose, various percentages of polycaprolactone and chitosan have combined with vitamin E and produce with two methods. The surface morphology of nanofibers was studied by microscopy (SEM). By using infrared spectrometer (FTIR) the links between vitamin and nanofiber were studied. The effects of drug release and antimicrobial from nanofibers with standard (AATCC100) were measured. Based on the results of tests it was found that nanofiber PCL-chitosan containing vitamin with a ratio of 70-30 and a concentration of 1 gr and 0.3 gr that has produced with electrospinning, was shown the best speed and the best release in compared to concentrations and the other ratios and the speed of electrospinning was more than finishing and it had 81% Antimicrobial effects.
