“…The critical stage of washing fastness was achieved with the carboxyl functionalized CNT/TPU/Dopamine composite using ultrasonic deposition process. Washing fastness achievements can be attributable to the interactions among TPU and dopamine polymers [241]. Hydrophobic composites formed with silk fibroin/PANI composites and its anti-wetting property were ascertained with the porous structures, entrapping the bundles of air pockets [242].…”

The Conducting of polymers belongs to the class of polymers exhibiting excellence in electrical performances because of their intrinsic delocalized π- electrons and their tunability ranges from semi-conductive to metallic conductive regime. Conducting polymers and their composites serve greater functionality in the application of strain and pressure sensors, especially in yielding a better figure of merits, such as improved sensitivity, sensing range, durability, and mechanical robustness. The electrospinning process allows the formation of micro to nano-dimensional fibers with solution-processing attributes and offers an exciting aspect ratio by forming ultra-long fibrous structures. This review comprehensively covers the fundamentals of conducting polymers, sensor fabrication, working modes, and recent trends in achieving the sensitivity, wide-sensing range, reduced hysteresis, and durability of thin film, porous, and nanofibrous sensors. Furthermore, nanofiber and textile-based sensory device importance and its growth towards futuristic wearable electronics in a technological era was systematically reviewed to overcome the existing challenges.

“…In addition, various drugs and bioactive ingredients can be easily encapsulated into the nanofibers through the electrospinning technique, which can impart nanofibers with predetermined biological behaviors [ 33 , 34 ]. Moreover, a wide variety of post-treatment processes are perfectly suitable for the modification of electrospun nanofibers to further improve the properties and functions of as-prepared nanofibers [ 35 , 36 ]. The direct transformation of electrospun nanofibers into textile yarn-like structures, also named as nanofiber yarns (NYs), provides an innovative routine for renewing and updating the existing microfiber yarns (MYs) made from the traditional melt, dry, and wet spinning techniques [37] .…”

A flexible strain sensor with excellent mechanical and electrical properties was fabricated by depositing carboxylated multiwalled carbon nanotubes (CNTs) and graphene (Gr) onto thermoplastic polyurethane (TPU) nanofibrous membranes. The deposition efficiency and fastness of CNTs and Gr particles on TPU nanofibrous membranes were improved by vacuum assisted deposition and ultrasonication. Furthermore, a flexible strain sensor with excellent sensing performance was obtained by optimizing the optimal hybrid ratio between CNTs and Gr. Electromechanical experiments showed that the strain sensor had a wide working range of 172% with a high‐gauge factor of approximately 217 for TPU/5CNTs5Gr composite. Moreover, the TPU/5CNTs5Gr composite also exhibited good durability in 10,000 tensile loading‐unloading cycles, and had superior sensing performance when monitoring the bending motions of human finger, elbow and knee.
