Recent Advances in Electrospun Polylactic Acid-Based Nanocomposites with Carbon Nanotubes: Characterization, Optimization, and Biomedical Applications

Recent advances in electrospun polylactic acid (PLA)/carbon nanotube (CNT) composites have created new avenues for enhancing properties and expanding biomedical applications of these materials. This study investigates the impact of incorporating CNT on the mechanical, thermal, and electrical properties of electrospun PLA nanofibers. Findings reveal that the presence of CNT within the polymer matrix leads to marked improvements in tensile strength, Young's modulus, thermal stability, and electrical conductivity—properties that are critical for biomedical applications, particularly in tissue engineering scaffolds and biosensors. Furthermore, the distribution of carbon nanotubes and optimization of electrospinning parameters, including solution concentration, solvent type and ratio, applied voltage, and working distance, play essential roles in achieving nanofibers with uniform morphology and enhanced properties. This study concludes with an analysis of future challenges and opportunities to further refine CNT dispersion and advance the mechanical performance and biocompatibility of these nanocomposites for applications in tissue engineering and regenerative medicine.
