The production of nanofibers has become a significant area of research due to their unique properties and diverse applications in various fields, such as biomedicine, textiles, energy, and environmental science. Electrospinning, a versatile and scalable technique, has gained considerable attention for its ability to fabricate nanofibers with tailored properties. Among the wide array of conductive polymers, poly(3,4-ethylenedioxythiophene) (PEDOT) has emerged as a promising material due to its exceptional conductivity, environmental stability, and ease of synthesis. The electrospinning of PEDOT-based nanofibers offers tunable electrical and optical properties, making them suitable for applications in organic electronics, energy storage, biomedicine, and wearable technology. This review, with its comprehensive exploration of the fabrication, properties, and applications of PEDOT nanofibers produced via electrospinning, provides a wealth of knowledge and insights into leveraging the full potential of PEDOT nanofibers in next-generation electronic and functional devices by examining recent advancements in the synthesis, functionalization, and post-treatment methods of PEDOT nanofibers. Furthermore, the review identifies current challenges, future directions, and potential strategies to address scalability, reproducibility, stability, and integration into practical devices, offering a comprehensive resource on conductive nanofibers.

This study investigates the influence of three critical 3D‐printing parameters—layer height, print speed, and extrusion temperature—on the mechanical properties of liquid crystalline polymer 3D‐printed specimens, using a low‐end 3D‐printer. The extrusion process during 3D‐printing can further align the molecular domains within the material along a common direction, leading to a reinforced polymer structure with superior properties. Specifically, the tensile strength, deformation at rupture, and flexural elastic modulus were evaluated to determine how layer height, print speed, and extrusion temperature affect the structural integrity of the printed components. The results demonstrate a significant improvement in both tensile strength and flexural modulus with the reduction of layer height from 0.16 to 0.08 mm. The study highlights the challenges associated with interlayer adhesion in liquid crystalline polymers 3D‐printing, which is crucial for optimizing the mechanical performance of printed parts. Post‐processing annealing was conducted over a wide temperature range (100°C–250°C), revealing its potential to further enhance material strength, though molecular diffusion emerged as a limiting factor in its effectiveness. By successfully demonstrating these advancements with a low‐end 3D printer, this research paves the way for wider adoption of liquid crystalline polymers in additive manufacturing. The use of accessible and cost‐effective equipment ensures that these high‐performance materials can be integrated into diverse applications, promoting democratization of advanced polymer technologies.
