A Novel Mesoporous Taurine-Doped Polyaniline/PVA Electrospun Composite Nanofiber: Comprehensive Study

Conductive polymers, in particular polyaniline (PANI), are gaining a lot of attention because of their unique combination of electrical conductivity, flexibility, and tunable properties, which make them ideal for applications in energy storage, sensors, and flexible electronics. However, PANI's limited mechanical properties, poor machinability, and conductivity loss in physiological environments make them unsuitable for practical use. To overcome these problems, PANI is frequently incorporated into polymer composites. In order to improve PANI's properties, taurine (Tau), a biocompatible amino acid, is doped into PANI, and T-PANI/PVA composite nanofibers are made by electrospinning. Taurine improves PANI's conductivity and biocompatibility by acting as an efficient bioactive dopant with its sulfonic acid group. X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), Brunauer–Emmett–Teller (BET) surface area analysis, UV–visible spectroscopy, photoluminescence (PL) spectroscopy, Thermogravimetric analysis (TGA) and mechanical studies were among the methods used to systematically characterize the electrospun (T- PANI/PVA) composite fibers. According to the findings, taurine doping enhances the nanofibers' mechanical stability, electrical conductivity, and thermal characteristics along with improved ion transport and molecular alignment. These results imply that taurine-doped PANI/PVA nanofibers, equipped with the conductive qualities of PANI, mechanical strength of PVA and the biocompatibility of taurine, provide a potential platform for flexible electronics, sensors, and biomedical applications.
