Abstract
- In this work, zein nanofiber membranes loaded with ε-polylysine-polyphenol-polyaspartic acid were prepared using electrospinning for the controlled delivery of polyphenols. The loading efficiency (LE) and loading capacity (LC) of polyphenols in ε-polylysine/polyaspartic acid hydrogels were determined. Characterization of the films was carried out using water contact angle (WCA) measurement, thermal analysis (DSC/TG), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The study showed that the embedding rates of all samples reached more than 80%. The structural characterization results showed that the nanofiber membranes loaded with hydrophobic polyphenols were more stable and no new compounds formed during electrostatic spinning. The
