Abstract
- This paper reports the investigation about the usage of an epoxy (EP)-coated spinneret for the preparation of medicated electrospun nanofibers. Cellulose acetate (CA) and acetaminophen (APAP) were used as the polymeric carrier and model drug, respectively. The electrospinning was undertaken using both EP-coated spinneret and traditional stainless steel capillary as spinnerets. According to the images from scanning electron microscopy, it is obvious that the nanofibers produced using the EP-coated spinneret had a finer diameter and a narrower size distribution (450±90 nm) than nanofibers fabricated using stainless steel equivalent (660±180 nm). In vitro dissolution tests revealed that the sustained-release profiles of nanofibers from the EP-coated spinneret were superior to those of their stainless steel equivalents, although APAP existed in a similar amorphous state in both nanofibers. Because the EP-coated material can exploit the electrical forces more effectively than its steel analogue, it can enhance the electrospinning technique for producing polymeric functional nanofibers.
