Drug release system based on a composite polycaprolactone nanofiber membrane with dual functionality of shape memory effect and antibacterial ability.

ABSTRACT: In this study, a multifunctional composite membrane based on polycaprolactone nanofibers having controlled drug release, shape memory effect, and antibacterial ability was successfully prepared by the electrospinning technique. The addition of graphene oxide (GO), zinc oxide nanoparticles (ZnO NPs), polyethylene glycol (PEG), and berberine (BBR) strongly affected the morphology, crystalline degree, melting temperature, and shape memory performance of the composite membrane, thanks to the physical crosslinking network formed by the hydrogen bonding or van der Waals interactions between the components. As a result, the recovery ratio of the composite membrane reached a higher value (76.3% ± 0.7%) than that of the PCL fiber membrane (22.8% ± 0.7%). The additional components significantly impr
