“…1,2 Among the different forms of advanced carbon materials, porous carbon has attracted the interest of scientific communities due to its high surface area, pore volumes, and easy diffusion of ions/molecules. [3][4][5][6][7][8][9] Equipping carbon with different-sized pores and shapes lowers the density of the materials and expands its surface area to accelerate interfacial energy and mass transfer, which is crucial and decisive in many surface-related physical and chemical processes. The addition of heteroatoms influences electronic, structural, and surface-active properties.…”

These rGO/PPy composites have been integrated to investigate the use of supercapacitors and sensors with other materials such as cellulose, polyacrylonitrile, carbon dots, and polyaniline.…”

The tunable mechanical and stretchable properties of thermoplastic polyurethane (TPU), in conjunction with its convenience of surface modification, have attracted interest for various sensing materials. This study examines the process of creating conductive and flexible TPU composites by incorporating carbon materials such as graphene oxide (GO) and polypyrrole (PPy). The suitability of these composites for ammonia gas sensing and as supercapacitor electrode materials is investigated for evaluating the potential of the dual-functioning hybrid composites. Two fabrication process sequences are examined: one involves surrounding TPU with GO and subsequently adding PPy, and the other involves wrapping TPU with PPy and incorporating GO. The results reveal that the fabrication process sequence can be adapted to control the mechanical and electrical properties of TPU composites. Furthermore, the conductive TPU composites exhibit significant potential for dual-function applications as both ammonia gas sensors and supercapacitor electrode materials. Among the TPU composites tested, TPU-PPy-GO demonstrates the best performance in terms of gas sensing and supercapacitor capabilities. A further evaluation of TPU-PPy-GO focuses on its selectivity and sensitivity to other reducing gases (triethylamine, ethanol, and methanol) and its galvanostatic charge−discharge properties for energy-storage electrode applications. By modification of the fabrication sequence, conductive TPU composites can be used extensively as chemical sensors and energy storage materials.

“…It exhibited the specific capacitance of 140 mF g −1 and retained for 5000 cycles under mechanical stress, these films can be employed for wearable electronic device applications. [ 14 ] Zhang et al synthesized chemically a worm‐like morphology of PEDOT:Tos on polypropylene nonwoven fabric and it exhibited a promising thermoelectric performance. The morphology of PEDOT:Tos on propylene nonwoven fabric is one of the key parameters getting more heat energy for the fabricated stretchable thermoelectric devices.…”

Stretchable conducting films are a prime necessity for future stretchable and wearable electronics. In this work, highly conducting poly(3,4 ethylenedioxythiophene):Tosylate (PEDOT:Tos) films are deposited on extremely stretchable styrene‐ethylene‐butylene‐styrene (SEBS) substrates via vapor phase polymerization (VPP) and their inherent properties are systematically studied. The charge transport and electrical properties of VPP PEDOT:Tos stretchable films are measured from room temperature down to the low temperature of 5 K. Interestingly, the mechanical properties of the stretchable substrate lead to buckling of the PEDOT:Tos that affect the electrical conductivity but not the charge carrier mobility, optical, and structural properties. The VPP PEDOT:Tos on the stretchable SEBS substrate show a semiconducting behavior as electrical resistance is enhanced upon cooling from room temperature to 5 K. Such kind of stretchable conducting films can be used for stretchable transistors, wearable sensing, energy storage, and electrochromic applications.
