“…The high extent of interactions in the oCVD PPy-coated electrospun PU fiber mats leads to much enhanced thermal stabilities at lower temperatures as compared to the one-side-coated PU solid films. The approximate weight percentage of oCVD PPy can be calculated from the residual weight of the samples and is summarized in Table . The absolute value of oCVD PPy content in the PU solid film is very low.…”

Electrically conductive polymer nanocomposites have been the subject of intense research due to their promising potential as piezoresistive biomedical sensors, leveraging their flexibility and biocompatibility. Although intrinsically conductive polymers such as polypyrrole (PPy) and polyaniline have emerged as lucrative candidates, they are extremely limited in their processability by conventional solution-based approaches. In this work, ultrathin nanostructured coatings of doped PPy are realized on polyurethane films of different architectures via oxidative chemical vapor deposition to develop stretchable and flexible resistance-based strain sensors. Holding the substrates perpendicular to the reactant flows facilitates diffusive transport and ensures excellent conformality of the interfacial integrated PPy coatings throughout the 3D porous electrospun fiber mats in a single step. This allows the mechanically robust (stretchability > 400%, with fatigue resistance up to 1000 cycles) nanocomposites to elicit a reversible change of electrical resistance when subjected to consecutive cycles of stretching and releasing. The repeatable performance of the strain sensor is linear due to dimensional changes of the conductive network in the low-strain regime (ε ≤ 50%), while the evolution of nano-cracks leads to an exponential increase, which is observed in the high-strain regime, recording a gauge factor as high as 46 at 202% elongational strain. The stretchable conductive polymer nanocomposites also show biocompatibility toward human dermal fibroblasts, thus providing a promising path for use as piezoresistive strain sensors and finding applications in biomedical applications such as wearable, skin-mountable flexible electronics.

Synthesis and application of Fe ₃ O ₄ @nanocellulose/TiCl as a nanofiller for high performance of quasisolid‐based dye‐sensitized solar cells

Summary In this research, to optimize the surface of the photoanode, two different types of surface coatings were used and their effects on the photovoltaic parameters were investigated. Also, to compare the two different electrolytic systems based on liquid and gel‐state electrolyte, the novel magnetic core‐shell nanocellulose/titanium chloride (Fe3O4@)NCs/TiCl) nanocomposite was introduced into a polymeric system as a nanofiller to decrease the crystallinity of the polymer and enhance the diffusion of triiodide ions in quasisolid‐state dye‐sensitized solar cells (QS‐DSSCs). For this purpose, Fe3O4@)NCs/TiCl was synthesized by coprecipitation of Fe3+ and Fe2+ ions in the presence of nanocellulose and then used as magnetic support for bonding TiCl4 to prepare QS‐DSSCs. Containing a 10.0 wt% magnetic nanocomposite, it displayed a higher apparent diffusion coefficient (Dapp) for I3− ions (4.10 × 10−6 cm2/s) than the gel polymeric electrolyte (GPE) did (1.35 × 10−6 cm2/s). GPEs were characterized using various techniques including current density‐voltage curves, AC impedance measurements, and linear sweep voltammetry (LSV). The photovoltaic values for the short‐circuit current density (Jsc), open‐circuit voltage (VOC), and fill factor (FF) and the energy conversion efficiency (η) of the novel Fe3O4@NCs/TiCl nanocomposite–based QS‐DSSCs were 14.90 mA cm−2, 0.757 V, 64%, and 7.22%, respectively.

“…PGE is a stable gel network constructed by filling a polymer matrix with a liquid electrolyte, which shows lower vapor pressure, lower contact resistance, and higher electrical conductivity with excellent thermal stability, mechanical stability, and durability. In recent years, numerous polymers have been prepared and applied as the PGE matrix for DSSCs, such as poly(ethylene oxide)(PEO), poly(vinyl pyrrolidone) (PVP), poly(dimethylsiloxane) (PDMS), and polyurethanes (PU). − To obtain high ion conductivity, these polymers are often designed and fabricated into porous structures to provide more space for liquid electrolyte storage . For example, Manafi et al fabricated a blend of porous poly(vinylidene fluoride- co -hexafluoropropylene) (PVDF-HFP) and poly(ethylene oxide) (PEO).…”

To overcome the drawbacks of solvent evaporation and leakage from the liquid electrolyte in dye-sensitized solar cells (DSSCs), a polymer gel electrolyte (PGE), based on polydopamine (PDA)-modified electrospun polyvinylidene fluoride (PVDF) nanofibers, PDA@PVDF, was prepared and applied in quasi-solid DSSCs (QS-DSSCs). The PDA coating increased the wettability of the liquid electrolyte by improving the distribution of the ionic liquid electrolyte. This, in turn, enhanced the ion conductivity of the PGE as well as the stability of QS-DSSC. The PDA@PVDF nanofiber membrane exhibited a satisfactory ultimate tensile strength of 9.3 MPa with a failure elongation of 130%. Such high toughness provided excellent mechanical support for the PGE. Owing to the unique pore connected structure of nonwoven nanofibers as well as the reduced surface tension with the liquid electrolytes, the PGE-based QS-DSSC retained 95.7% of the short circuit current from the liquid-electrolyte-based DSSC and showed an energy conversion efficiency of 8.26%. No significant impacts were observed for the open-circuit voltage and fill factor. More importantly, the QS-DSSCs using PDA@PVDF-based PGE showed a significantly improved solar cell stability under both indoor and outdoor conditions.
