“…Despite their potential, the obstacle of retaining the antibacterial loading into substrate materials remains a point of contention . Various techniques to augment the antibacterial agent’s adhesion onto textiles and retain its antibacterial properties have been explored, such as treating cotton fabric with an alkali solution, plasma electrospinning to form active chemical surface groups, and mixing the electrospun solution with high-temperature adhesive powder. − Nevertheless, the antibacterial longevity of such coatings is significantly compromised after approximately five laundering cycles due to their tenuous adherence to the textile. , …”

This study addressed the limited antibacterial durability of textile materials, which has suppressed their applications in preventing infectious disease transmission. A class of highly durable antibacterial textiles was developed by incorporating protonated polyaniline (PANI) textile with poly-(acrylic acid) (PAA) as the functional binder via cross-linking polymerization. The resulting PAA−PANI textile exhibits exceptional electrical conductivity, reaching 8.33 ± 0.04 × 10 −3 S/cm when cross-linked with 30% PAA. Remarkably, this textile maintains its electrical stability at 10 −3 S/cm even after 50 washing cycles, demonstrating unparalleled durability. Furthermore, the PANI−PAA textile showcases remarkable antibacterial efficacy, with 95.48% efficiency against Pseudomonas aeruginosa and 92.35% efficiency against Staphylococcus aureus bacteria, even after 50 washing cycles. Comparatively, the PAA−PANI textile outperforms its PANI counterpart by achieving an astounding 80% scavenging activity rate, whereas the latter only displayed a rate of 3.22%. This result suggests a solid integration of PAA−PANI into the textile, leading to sustainable antioxidant release. The successful cross-linking of PAA−PANI in textiles holds significant implications for various industries, offering a foundation for the development of wearable textiles with unprecedented antibacterial durability and electrical stability. This breakthrough opens new avenues for combating infectious diseases and enhancing the performance of wearable technologies.

The demand for wearable electronics has driven the development of conductive fabrics, particularly those incorporating polyaniline (PANI) that is known for its high electrical conductivity, flexibility, and ease of fabrication. However, the limited stability and durability of the conductive fabric, especially during washing, present significant challenges. The drawbacks can be traced by weak physical attachment between the fabric and the conductive coating, leading to a decrease in conductivity over time. These drawbacks significantly impact the fabric's functionality and performance, highlighting the need for effective solutions to enhance its stability and durability. This study focuses on addressing these challenges by employing a thermochemical treatment. A hydrophilic surface of the polyester fabric is obtained after the treatment (hydrolysis), followed by grafting of PANI on it. The adhesion between PANI and the polyester fabrics was found to be enhanced, as proved by contact angle analysis. Furthermore, the PANI-hydrolyzed fabrics (treated) demonstrated stable conductivity (∼10 −3 S cm −3 ) even after 10 washing cycles, showcasing their excellent durability. In comparison, the unhydrolyzed PANI fabric experienced a drop in conductivity by three orders of magnitude. X-ray photoelectron spectroscopy via N 1s core line spectra showed chemical shifts and quantified the level of doping through PANI's protonation level. We found that PANI-hydrolyzed fabrics preserved their dedoping level from 44.77 to 42.68%, indicating improved stability and extension of their electrical properties' lifetime after washing as compared to unhydrolyzed (untreated) fabrics, from 36.99 to 26.61%. This investigation demonstrates that the thermochemical approach can effectively enhance the durability of conductive PANI fabrics, enabling them to withstand the washing process while preserving their electrical endurance.
