“…As the concentration of ANI in the reaction system increased, the load of PANI gradually increased on the surface of CDM, which caused the hydrophilicity (Table 1) and the transparency (Figure S2) of CDM-PANI to gradually deteriorate. 35 The asymmetric decoration of the cellulose membrane would endow its opposite surfaces with different properties. In addition to the morphology, the wettability of both sides of CDM-PANI was also studied.…”

The mysterious ability of a lotus leaf to self-clean (upper surface is superhydrophobic and lower surface is superhydrophilic) has inspired the design of conductive Janus cellulose composite membranes with signal-capturing properties and biocompatibility of cellulose. Herein, diffusion-controlled polymerization was used to construct Janus conductive electronic skin. Specifically, dialysis membranes containing an aniline (ANI) solution were put into an APS solution. Due to the diffusion of APS, ANI polymerized inside the dialysis membranes and the thickness of polyaniline (PANI) could be controlled by the concentration of ANI. Finally, composite membranes (CDM-PANI) with Janus performance were achieved. The resistance of the conductive side of CDM-PANI showed an inverse proportional relationship with the thickness of PANI. When the thickness of PANI was increased to 1.37 μm, the resistance of CDM-PANI became stable (55.3 Ω•cm). More importantly, the PANI layer that was decorated by the diffusion-controlled polymerization method imparted excellent firmness to cellulose-based membranes. The signalcapturing properties of CDM-PANI in response to tiny motions, organic gases, temperature, and illuminance of the membrane were studied, and these results demonstrated that the relative resistance of Janus membranes exhibited a good linear correlation with the concentration of organic gases, temperature, and illuminance. Therefore, the membranes could be used to detect the concentration and intensity of organic gases, temperature, and illuminance. This easy-to-tune strategy provided a new design philosophy for the fabrication of Janus conductive membranes.

Recent Progress in Conducting Polymer Composite/Nanofiber-Based Strain and Pressure Sensors

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.
