Highly Efficient Photothermal Icephobic/de-Icing MOF-Based Micro and Nanostructured Surface.

ABSTRACT: Photothermal materials have gained considerable attention in the field of anti-/de-icing due to its environmental friendliness and energy saving. However, it is always significantly challenging to obtain solar thermal materials with hierarchical structure and simultaneously demonstrate both the ultra-long icing delay ability and the superior photothermal de-icing ability. Here, a photothermal icephobic MOF-based micro and nanostructure surface (MOF-MNS) is presented, which consists of micron groove structure and fluorinated MOF nanowhiskers. The optimal MOF-M₂₅₀ NS can achieve solar absorption of over 98% and produce a high temperature increment of 65.5 °C under 1-sun illumination. Such superior photothermal-conversion mechanism of MOF-M₂₅₀ NS is elucidated in depth.
