Metamaterials at terahertz frequencies offer unique opportunities, but are challenging to fabricate in bulk. We adapt the fabrication procedure for microstructured polymer optical fibers to inexpensively fabricate metamaterials potentially on an industrial scale. We produce polymethylmethacrylate fibers containing ~10 μm diameter indium wires separated by ~100 μm, which exhibit a terahertz plasmonic response.
FAQs
Polymer concentration and flow rate influence how much material enters the charged jet and how readily that jet can thin. Concentration changes the polymer content available to form the fiber, while flow rate changes the amount delivered over time. Adjusting these variables helps researchers tune diameter and improve consistency across the fabricated fibrous material.
Applied voltage affects the electrical forces that stretch the polymer solution, whereas collector distance influences the travel path available for jet stretching and solvent evaporation. Together, these conditions shape the final fiber diameter. Maintaining controlled values is important because changes in either factor can alter diameter uniformity and the resulting structure of the material.
Consistent diameter supports more reproducible mechanical, structural, and transport behavior. Fiber thickness contributes to characteristics such as porosity and surface area, which can influence degradation and interactions with cells. By limiting diameter variation, researchers can compare materials more reliably and better connect fabrication conditions with the performance of tissue-engineering or delivery systems.
A polymer solution is delivered into an electric field, where charging forms a stretched jet that travels toward a collector. During this path, the jet undergoes thinning and solvent evaporation before depositing as fibers. Researchers adjust polymer concentration, flow rate, applied voltage, and collector distance to obtain the desired diameter and reproducibility.
Controlled fiber dimensions support tissue-engineering scaffolds, drug-delivery systems, filtration materials, and other biomimetic structures. In each case, diameter can contribute to the material’s surface area, porosity, transport behavior, degradation, or cell interactions. Reproducible control therefore helps researchers design fibrous systems with more predictable structural and functional performance.
Adjusting diameter provides a way to tailor interconnected structural features and surface-related properties in fibrous materials. These features can affect transport, degradation, and how cells interact with a scaffold, while also influencing the behavior of drug-delivery systems. The same fabrication strategy can therefore be adapted to different bioengineering requirements while preserving measurable control over material structure.
