摘要

碳前驱体激光诱导石墨烯（LIG）可用于制造半导体、能源和生物医学设备。为了扩大其应用领域，亟需探索将生态友好型前驱体转化为石墨烯。本文研究了一种结合纸基 LIG 的仿生结构和表面改性的方法，用于生产非对称超润湿 Janus 膜。分子动力学模拟说明了纸基 LIG 的转化机制。十八硫醇改性的仿生新月形 LIG 表面具有超疏水性能，水接触角 (WCA) 为 157°，水滑动角 (WSA) 为 3.5°。等离子体改性的 LIG 表面具有超亲水性，WCA 为 0°。实验证明，Janus 膜能高效分离轻油-水和重油-水混合物。此外，Janus 膜的超疏水表面具有优异的光热性能，表现出卓越的抗结冰能力。所提出的仿生 Janus 膜制造方法将为 LIG 应用提供一种生态友好型解决方案。

Eco-friendly bionic superwetting Janus membranes prepared from paper-based laser-induced graphene for photothermal anti-icing and on-demand oil–water separation

Laser-induced graphene (LIG) from carbon precursors is used in the manufacture of semiconductors, energy and biomedical devices. To expand its field of applications, there is a strong need to explore LIG conversion of eco-friendly precursors. An approach combining bionic structures and surface modification on paper-based LIG was investigated for producing asymmetric superwetting Janus membranes. Molecular dynamic simulation illustrates the paper-based LIG conversion mechanism. The Octadecanethiol-modified bionic crescent-shaped LIG surface exhibited superhydrophobic performance, the water contact angle (WCA) is 157° and the water sliding angle (WSA) is 3.5°. The plasma-modified LIG surface was superhydrophilic with the WCA of 0°. The Janus membranes were demonstrated for high-efficient separation of light oil–water and heavy oil–water mixtures. Furthermore, the superhydrophobic surface of the Janus membranes with excellent photothermal properties exhibited superior anti-icing capability. The proposed approach for fabrication of bionic Janus membranes would provide an eco-friendly solution to LIG applications.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
