“…Icing accretion is a common physical phenomenon that can cause performance degradation and loss of function, resulting in serious safety issues and economic losses in many systems, including solar panels, aircraft, high-speed rail, power lines, etc. − Passive anti-icing surfaces such as slippery liquid-infused porous surfaces (SLIPS) exhibit ultralow icing adhesion due to the transformation of the icing interface on SLIPS from “solid–solid contact” to “solid-liquid-solid contact”. − However, the widespread application of SLIPS surfaces is hindered by the loss of lubricating oil due to erosion caused by air–liquid flow and ice shedding. Therefore, an alternative method of constructing liquid-like slippery surface by covalently grafting polydimethylsiloxane (PDMS) brush or organic molecules with chemical bonds is developed, which can effectively improve the durability of ultraslippery surfaces. − However, passive anti-icing alone is insufficient to, achieve complete anti-icing under dynamic icing conditions. , A combination of active and passive anti-icing/deicing methods is necessary.…”

A photo/electrothermal surface can convert sunlight and electricity into heat to solve icing problems. The combination of active photo/electrothermal surfaces with passive slippery surfaces provides a highly efficient strategy for all-day anti/ deicing. However, the lack of transparency remains a primary impediment to the widespread application of these anti-icing measures in photovoltaics, windshields, and other fields. Herein, we report a bilayer transparent photo/electrothermal coating with a liquid-like slippery property for all-day anti/deicing. The prepared coating exhibits ultraslippery, low ice adhesion, and enhanced stability properties through covalent grafting of polydimethylsiloxane (PDMS) brushes in a cross-linked skeleton of epoxy. Moreover, the coating demonstrates a visible transmittance of up to 77% and effectively absorbs ultraviolet and near-infrared light due to the addition of ultraviolet and infrared absorbers, resulting in a temperature increase under sun illumination. The bottom indium tin oxide layer is fabricated to provide the composite coating with electrothermal capability, so that it can achieve all-weather deicing. The coupling of photo/electrothermal and slippery properties can promote the rapid removal of grown ice in a short time. The slippery properties and their exceptional durability under mechanical, optical, and thermal conditions render the composite coatings highly promising for engineering applications.
