Flexible capacitive pressure sensors play an important role in electronic skin and human–machine interaction due to their high sensitivity and convenient preparation, comparing with those resistive/piezoresistive sensors. However, due to the complexity of the application environment, reported capacitive sensors often experience signal instability by electromagnetic interference and proximity effects. The great challenge for capacitive sensors is to maintain sensitivity and wide linear range while reducing interference. This study proposes a high anti‐jamming capacitive flexible pressure sensor with polyvinylidene fluoride (PVDF)@AgNWs@TiO2 film as the dielectric layer. Core–shell structure‐based AgNWs@TiO2 is embedded into the PVDF film. The introduction of the core–shell structure not only enhances the initial capacitance but also balances the dielectric constant, dielectric loss, and breakdown strength of the dielectric layer. The sensor is validated to exhibit a high signal‐to‐noise ratio for a variety of interference sources and is demonstrated with an intelligent glove sensing system, which provides a new idea for developing a high anti‐jamming capacitive flexible pressure sensor.

“…TiO 2 /g-C 3 N 4 has a wide light absorption range and low photoinduced carrier recombination rate, degraded rhodamine B (RhB) dye by 97% after 40 min of irradiation. Loading noble metals such as Ag, Au, and Pt on the surface of TiO 2 can reduce the carrier recombination rate and improve the efficiency of TiO 2 photocatalysis [ 29 , 30 , 31 ]. …”

In this paper, Ag-TiO2 photocatalysts with different Ag contents (1 mol%–5 mol%) were prepared and applied to cement mortar. The photocatalytic performance of Ag-TiO2 and photocatalytic cement mortar under UV light and simulated solar light was evaluated. The results showed that Ag loading on the surface of TiO2 could reduce its band gap width and increase its absorbance in the visible region, and 2% Ag-TiO2 had the highest photocatalytic activity under UV light, the degradation rate of methyl orange (MO) was 95.5% at 30 min, and the first-order reaction constant k was 0.0980 min−1, which was 61.7% higher than that of TiO2, and 5% Ag-TiO2 had the highest photocatalytic activity under solar light, the degradation rate of methylene blue (MB) was 69.8% at 40 min, and the first-order reaction constant k was 0.0294 min−1, which was 90.9% higher than that of TiO2. The photocatalytic mortar prepared by the spraying method has high photocatalytic performance, The MO degradation rate of sample S2 under UV light was 87.5% after 120 min, MB degradation rate of sample S5 under solar light was 75.4% after 120 min. The photocatalytic reaction conforms to the zero-order reaction kinetics, which was 1.5 times–3.3 times higher than that of the mixed samples and has no effect on the mechanical properties of mortar.

“…19 As a kind of nanoparticle, titanium dioxide (TiO 2 ) has been widely used in coatings, chemical fibers, and other fields. 20,21 For example, Al-Balakocy et al 22 treated polyester-cotton blended fabric with alkali, and then loaded the fabric with TiO 2 through a hightemperature and high-pressure dyeing machine. The modified fabric had good antibacterial and antiultraviolet (UV) properties after five washings.…”

The comfort of polyester (polyethylene terephthalate or PET)as well as its reusability is greatly affected by its hydrophobicity. To improve the hydrophilicity of PET, titanium dioxide (TiO2) and gelatin were proposed to treat polyester by surface coating in this study. TiO2 and gelatin were selected because of their excellent ecological performance and wide usage. PET fabric had a super-hydrophilic surface and satisfied mechanical properties after various modifications. The synchronous treatment produced a significant effect. The fabric was coated with a dispersion of 4 g/l TiO2 and 5 g/l gelatin by the two-dip and two-rolling process. The static water contact angle of TiO2/gelatin-coated PET fabric reached 0° within 45 s. The results indicated that the PET fabric coated with TiO2/gelatin exhibited remarkable super-hydrophilicity and excellent resistance to wear and washing. Furthermore, the altered fabric underwent evaluation to assess its tensile fracture properties, air permeability, and crease recovery, which influenced its wearability and comfort. These performances demonstrate the potential application of TiO2/gelatin-coated PET fabric in textiles and apparel.
