Regulating the Alkyl Chain Length of Quaternary Ammonium Salt to Enhance the Inkjet Printing Performance on Cationic Cotton Fabric with Reactive Dye Ink

“…The high-resolution C1s XPS spectra of the untreated cotton fabric and cotton fabrics treated with different QASs are shown in Figure c. The C1s spectra are fitted to three components, where the peak at 284.6 eV belongs to C–C/C–H bonds, the peak at 286.3 eV is attributed to the C–O/C–N bond, and the peak at 287.8 eV is ascribed to the CO/O–C–O bond. − Compared with untreated cotton fabric, the peak content of the cation-modified cotton fabric at 284.6 eV increases with the alkyl chain length of QAS in Table S2. The reason for this phenomenon is that as the alkyl chain length of QAS increases, the content of the C–C bond in QAS increases so that the grafting of QAS on the cotton fabric results in the increase in C–C bond content.…”

Self-Cleaning Red-Toned Perylene Poly(aryl ether) Film with Superior NIR Reflectance for Passive Radiative Cooling

“…Several groups have demonstrated the use of porous polymer films as passive coolers. 21,22 Besides the decent cooling capacity, the construction of a porous polymer material has the advantages of facile preparation procedures, 23 low production cost, and ease of scaling up. 24 trapped pollutants from the surfaces to maintain the optical characteristics and durability against natural erosion require immediate attention.…”

“…A high emissivity at the atmospheric window (8–13 μm) can be simultaneously obtained by stacking the reflective layer with multilayer absorbers. , With the development of nano-manufacturing technology, adjustable reflectance and emissivity of materials were achieved by precisely controlling the shape, size, and arrangement of surface micro–nano structures. , However, the practical applicability of the above strategies are limited by challenges associated with the use of complex equipment and scaling up. , The high reflectivity can be realized through the mismatch in the refractive indexes of different materials hence scattering the incident wave at the interface, such as between the polymer matrix and the air pockets of a porous polymer. Several groups have demonstrated the use of porous polymer films as passive coolers. , Besides the decent cooling capacity, the construction of a porous polymer material has the advantages of facile preparation procedures, low production cost, and ease of scaling up . Despite the advantages, mitigation of the trapped pollutants from the surfaces to maintain the optical characteristics and durability against natural erosion require immediate attention .…”

Facile preparation of nickel phosphide for enhancing the photoelectrochemical water splitting performance of BiVO4 photoanodes

“…In contrast to high-cost noble metal, the development of earth-abundant, cost-effective transition metal-based OECs is of more practical significance. 27,28 Recently, transition metal phosphides, which have been shown to have superior electrocatalytic OER performance than transition metal oxides/hydroxides, 29 were adopted to modify BVO photoanode as OECs for enhancing the PEC water splitting performance. Kim and coworkers used CoP to modify Mo doped BVO photoanodes, which achieved 2.5 mA cm −2 at 1.23 V RHE .…”
