Abstract Scope |
Significant advancements in refined spinneret inventions and polymer innovations have catalyzed a remarkable expansion in the fabrication and diverse applications of multifunctional nanofiber-based products over the past two decades. However, our understanding of the underlying mechanisms responsible for nanofiber formation, particularly the processes of jet initiation and transitions, remains limited despite preliminary studies in the early 2000s. The limitations primarily stem from a lack of real-time monitoring capabilities and an incomplete understanding of the reinforcing mechanisms of functional materials. Leveraging progresses in modern high-speed cameras, lighting, and nanoindentation technique, we conducted a study to investigate the impact of iron oxide quantum dots (FeQDs) on the branching mechanisms, interfacial nano-mechanics, and chemistry of polyacrylonitrile (PAN)/FeQDs. The knowledge gained from this study is anticipated to offer fresh perspectives on the toughening mechanism of quantum dot-fiber composites, bridging gaps in understanding the connections between jet principals, fiber morphologies, interfacial nanomechanics, and surface chemistry. |
