Conformal Structured Ceramic Textiles with Passive and Active Heating Functionality

“…In order to fulfill dual-mode solar and joule heating in harsh cold environments (Figure a), a conformal polypyrrole@Al 2 O 3 ceramic fiber fabric is designed. The Al 2 O 3 ceramic fiber fabric had the advantages of flexibility, high-temperature resistance, and strong thermal stability. , In contrast, the PPy had the advantages of good conductive properties, excellent optical properties, , strong adhesion to fiber, and easy synthesis. , According to the amount of pyrrole in the synthesis process, the prepared composite ceramic fiber fabric was denoted as PPy@Al 2 O 3 -n, where n is the mass concentration of pyrrole monomer in the reaction solution. The optical photos of the synthetic PPy@Al 2 O 3 ceramic fiber fabric are shown in Figure c, in which the ceramic fiber fabric in Figure c (1–4) was Al 2 O 3 , PPy@Al 2 O 3 -10, PPy@Al 2 O 3 -20, and PPy@Al 2 O 3 -40 successively.…”

Electrospun nanofibers for medical face mask with protection capabilities against viruses: State of the art and perspective for industrial scale-up

“…In addition, the high fracture strength and tensile elongation provided by nanotextiles woven fabric plays an important role in the production of flexible and smart textile for healthcare wearable applications [ 30 , 302 ]. Recent electrospun nanofibers prepared by using polypyrrole (PPy) and covered with PAN-KCZ/ZnO nanofibers were twisted to prepare composite NYs with both photothermal and electrothermal properties for self-sterilization application [ 303 ]. The fabricated nanotextile woven provided a faster high-temperature response under the exposition to both light irradiation and electrical power, which promoted the continuous release of active KCZ in preventing the infection from bacteria pathogens.…”

Natural piezoelectric tourmaline mineral for piezocatalytic decomposition of organic dyes under vibration

“…[4][5][6][7] Among them, photocatalysis can harvest light energy to treat dye wastewater, which is widely reported. 8,9 The light-driven catalyst generates electron-hole pairs, which further decompose organic dye macromolecules through electrochemical redox generation of active substances. 10,11 However, low solar energy utilization and unresponsive in darkness limit its development.…”
