Abstract The insufficient density and discontinuity of solar energy photothermal superhydrophobic flexible film seriously affect the practical application. Light harvesting heat storage are effective ways to solve this problem. Inspired by viscous temperature‐regulating material within inflorescence Lobelia telekii arrangement bracts on its surface, a for photoheat is proposed that integrated three‐order trap one‐order storage. surface features microcone array with micro‐grooves, modified carbon nanotubes (MCNTs), layered structures microcapsules, forming three‐level trap. generated increases temperature partially absorbed inside microcapsule . stable polyurethane films structure (S x ) was elevated 3–5 °C compared without it (Flat‐S ), while MCNTs‐S MCNTs) exceeds S 2–6 °C. ice particles 0.45 completely dissolved 180 s under xenon lamp light source. Meanwhile, demonstrated superhydrophobicity outstanding anti‐fouling capabilities. fabricated realized biomimicry in both performance, providing strategy biomimetic de‐icing.

Synergistic Effect Between 0D CQDs and 2D MXene to Enhance the Photothermal Conversion of Hydrogel Evaporators for Efficient Solar Water Evaporation, Photothermal Sensing and Electricity Generation

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 30, 2024

Abstract Solar‐powered interfacial water evaporation is a promising technique for alleviating freshwater stress. However, the performance of solar evaporators still constrained by low photothermal conversion efficiency and high enthalpy. Herein, 0D carbon quantum dots (CQDs) are combined with 2D MXene to serve as hybrid material enhance light absorption ability, meanwhile sodium carboxymethyl cellulose (CMC)/polyacrylamide (PAM) hydrogels used substrate transport reduce enthalpy evaporation. The synergistic effect in CQDs/2D materials accelerate carrier transfer, inducing efficient localized surface plasmon resonance (LSPR) effect. This results enhanced efficiency. integrated hydrogel demonstrate rate (1.93 2.86 kg m −2 h −1 under 1 2 sunlights, respectively) (1485 J g ). In addition, applied sensing temperature difference power generation (TEG). TEG device presents an output density (230.7 mW ) sunlight. work provides feasible approach regulating controlling performances evaporators, gives proof‐of‐concept design multipurpose systems.
