Wettability Gradient-Induced Diode: MXene-Engineered Membrane for Passive-Evaporative Cooling

Nano-Micro Letters, Год журнала: 2024, Номер 16(1)

Опубликована: Март 21, 2024

Abstract Thermoregulatory textiles, leveraging high-emissivity structural materials, have arisen as a promising candidate for personal cooling management; however, their advancement has been hindered by the underperformed water moisture transportation capacity, which impacts on thermophysiological comfort. Herein, we designed wettability-gradient-induced-diode (WGID) membrane achieving MXene-engineered electrospun technology, could facilitate heat dissipation and moisture-wicking transportation. As result, obtained WGID obtain temperature of 1.5 °C in “dry” state, 7.1 “wet” was ascribed to its high emissivity 96.40% MIR range, superior thermal conductivity 0.3349 W m −1 K (based radiation- conduction-controlled mechanisms), unidirectional property. The proposed design offers an approach meticulously engineering membranes with enhanced transportation, thereby paving way developing more efficient comfortable thermoregulatory textiles high-humidity microenvironment.

The compelling integration of superhydrophobic coatings with light-to-heat conversion capabilities has garnered substantial interest due to their dual functionality encompassing passive anti-icing and deicing attributes. However, the insufficient mechanical stability environmental human health concerns stemming from extensive use organic solvents limit practical application. In this study, an all-waterborne photothermal coating (PCPAS) was prepared through synergy composite micro-nanoparticles derived carbon nanotubes (CNT), polydopamine (PDA), Ag particles fluorine-containing polyacrylic emulsion (PFA). PDA provided active sites for Ag+ reduction reaction enhanced interfacial interaction between CNT particles. enhancement enabled maintain stable superhydrophobicity after 260 times sandpaper abrasion 240 tape peeling. Simultaneously, micro-nanoparticle's ability gave excellent anti-icing/deicing capabilities. Under condition -20 °C, freezing time 30 μL water droplets extended 392 s, 2 × cm ice cubes placed on surface could completely melt only 1142 s under simulated sunlight irradiation a 1 kW/m2 intensity. addition, also had suitable self-cleaning properties substrate applicability. comprehensive attributes render it promising contender applications in challenging outdoor environments.
