Dual rotation centrifugal electrospinning: a novel approach to engineer multi-directional and layered fiber composite matrices

In this study, a dual rotation centrifugal electrospinning system (DRCES) is designed, developed, and used to prepare medicated fabrics. Through simultaneous rotation of both spinneret and collector, multi-directional blended fiber matrices (PVP and TPU) were deposited directly on the rotating collector. To detail the process, key stages of the centrifugal electrospinning process are elaborated, and the influence of gas infusion and collector rotation speed on resulting fiber morphologies was explored. Multi-directional fibrous structures show in vitro biocompatibility (fibroblast). Regulation of drug release rate was achieved using polymer composition and filament alignment. This study demonstrates a rapid fabrication method (~ 50 g/h) to engineer layered fibrous structures using DRCES, which provides a foundation for preparing complex drug matrices (single and multi-directional) for tailored active component release.
