“…Also, the absorption peaks of methylene (CH 2 ) and methyl (CH 3 ) between 2800 and 3000 cm −1 of the fabric are widened and strengthened, which further indicates the successful construction of the membrane on the fabric surface. From Figure 3G, the polyester fabric has characteristic peaks at 17.2°, 23.7° and 27.1° 31 . The WPU membrane has an obvious diffraction peak at 20°, and the position of the diffraction peak is consistent with other studies, indicating the presence of a large number of amorphous, microcrystalline and subcrystalline in the membrane 29 .…”

Noise reduction with materials of finite thickness has been a hot research topic. In this study, multi‐layer gradient fiber‐based composites integrating porous, resonant and damping structures were prepared for efficient sound absorption. Here, the effects of composite structure, fiber‐based thickness and micro‐perforated membrane fabric (MPMF) structure on the sound absorption of the composites were investigated. From the results, the sound absorption band of the composite can be effectively tuned by adjusting the structure of the MPMF or the thickness of the fiber‐based. In addition, the established acoustic model can accurately predict the sound absorption performance of the structure. It is worth mentioning that the gradient structure optimized by the algorithm exhibits broadband sound absorption (noise reduction coefficient of 0.42) and thin feature (thickness of 0.9 cm). Moreover, the medium and low frequency sound waves can be propagated and absorbed more easily by optimizing the structure of the composite. This work provides a reference for the preparation of multi‐layer gradient sound‐absorbing structures and the design of acoustic products in a specific frequency range.

“…Specifically, the adsorption band at 441 cm À1 and 578 cm À1 are owing to the bending vibrations of Bi-O bond; the strong peaks at 727 cm À1 and 820 cm À1 are attributed to the W-O and W-O-W bond of Bi 2 WO 6 , respectively. 16,46 These peaks prove the successful synthesis of Bi 2 WO 6 nanomaterials.…”

“…It is worth noting that the small peak at 1384 cm À1 corresponds to the vibration of N-O bond. 46,48 It was ascribed to the hydrolysis products of Bi(NO 3 ) 3 $5H 2 O, such as BiONO 3 and Bi 2 O 2 (OH)NO 3 . 31,49 This conclusion can also be veried by comparing the FTIR spectra of 0.97BWO before and aer the acid treatment.…”

“…Since it is difficult for Bi 2 WO 6 photocatalysts to be separated and collected for repeated operation, the growth of Bi 2 WO 6 nanomaterial on a porous substrate to make the immobilized photocatalyst is worth developing. Bi 2 WO 6 photocatalysts have been coated on different supporting materials such as indium-tin-oxide glass [51], stainless steel [52,53], and polyester fabric [54,55] to make immobilized photocatalysts, exhibiting some advantages such as enhanced photocatalytic activity, self-cleaning properties, and recyclability. Indigo is a widely used dye in the textile industry for the dyeing of blue jeans and other blue denim products [56].…”

Polydopamine-Bi2WO6-Decorated Gauzes as Dual-Functional Membranes for Solar Steam Generation and Photocatalytic Degradation Applications

et al. 2021

The dual-functional Bi2WO6/polydopamine (PDA)-modified gauze membrane has been developed for applications in photocatalytic degradation and solar steam generation. Two types of membrane were prepared by changing the growth sequence of Bi2WO6 nanomaterials and PDA on gauze substrates. The spatial distribution of Bi2WO6 and polydopamine has a great influence on light absorption, photocatalytic degradation, and solar steam generation performances. Bi2WO6 photocatalysts can absorb short-wavelength light for the photocatalytic decoloration of organic dyes. The photothermal polydopamine can convert light into heat for water evaporation. Besides, the gauze substrate provides water transport channels to facilitate water evaporation. The morphology, surface chemistry, and optical properties of Bi2WO6-PDA modified gauzes were characterized by scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and diffuse reflectance spectra. The photothermal properties, wetting properties, and solar steam generation rates of the composite films were also studied. Degradation of 96% of indigo carmine was achieved after being irradiated for 120 min in the presence of G/PDA/BWNP. The water evaporation rates of the G/BWP/PDA sample under the irradiation of an Xe lamp (light intensity = 1000 W/m2) reached 1.94 kg·m−2·h−1.
