Flexible and multifunctional textiles have potential applications in self-cleaning and portable electronic product applications, but the current problem that needs to be solved is to maintain their inherent breathability and flexibility while expanding other functional applications. Herein, we adopt the layer-by-layer assembly method to develop a multifunctional textile with superior asymmetric superhydrophobicity, excellent electromagnetic interference (EMI) shielding, outstanding photothermal conversion, and solar water evaporation. The synergistic effect of SiO nanoparticles/poly(dimethylsiloxane) (PDMS) and 1,1,2,2-perfluorooctyltriethoxysilane (PFOTES) endows the textile with a water contact angle of 160°. MXene provides high conductivity (1200 S/m) and EMI shielding effects (36 dB) for multifunctional textiles. In addition, the multifunctional textile exhibits excellent photothermal conversion, and satisfactory solar water evaporation efficiency (80%) and rate (1.22 kg/(m h)) under 1 sun. Therefore, the prepared multifunctional textile has great potential in multiscene applications.
柔性多功能纺织品在自清洁和便携式电子产品应用中具有潜在应用价值，但目前需要解决的问题是在扩展其他功能应用的同时，保持其固有的透气性和柔韧性。在此，我们采用层层组装法开发了一种多功能纺织品，该纺织品具有优异的不对称超疏水性、出色的电磁干扰（EMI）屏蔽性能、卓越的光热转换性能和太阳能水蒸发性能。SiO纳米颗粒/聚二甲基硅氧烷（PDMS）与1,1,2,2-全氟辛基三乙氧基硅烷（PFOTES）的协同作用赋予该纺织品160°的水接触角。MXene为多功能纺织品提供了高电导率（1200 S/m）和EMI屏蔽效果（36 dB）。此外，该多功能纺织品表现出优异的光热转换性能，在1个太阳光照下具有令人满意的太阳能水蒸发效率（80%）和速率（1.22 kg/(m²·h)）。因此，所制备的多功能纺织品在多场景应用中具有巨大潜力。
