“…Wet snow occurs when a portion of the snow melts as it falls, typically at temperatures just above freezing. Dry snow is powdery and occurs when temperatures are well below freezing, allowing it to remain low in LWC and can be easily blown by the wind [33]. Temperature variations between day and night, ground temperature, and sunlight exposure further affect the wetness of snow.…”

The performance of road vehicles degrades when driving in adverse weather conditions. Weather testing for vehicles is important to understand the impacts of precipitation on vehicle performance, such as driver visibility, autonomous sensor signal, tire traction, and structural integrity due to corrosion, to ensure safety. This tutorial summarizes the essential elements for performing realistic testing by applying physical and meteorological rationale to vehicle applications. Three major topics are identified as crucial steps for precise quantitative studies, including understanding the natural precipitation characteristics, estimating the perceived precipitation experienced by a moving vehicle, and selecting data collection strategies. The methods used in current practices to investigate the effects of rain and snow on road vehicles at common facilities of outdoor test tracks, drive-through weather chambers, and climatic wind tunnels are summarized. The testing techniques and relevant instrumentations are also discussed, with considerations of factors that influence the measured data, such as particle size distribution, precipitation intensity, wind-induced droplet dynamic events, accumulation behaviour, etc. The goals of this paper are to provide a tutorial with guidelines on designing weather testing experiments for road vehicles and to promote the idea of establishing standardized methodologies for realistic vehicle testing that facilitates accurate prediction of vehicle performance in adverse weather conditions.

“…At the northern areas in winter, freezing is inevitable, which causes many problems in the production and living fields of people, including traffic accident, aircraft crash, power line tower collapse, etc., which threatens human safety in severe cases. − For various complex application scenarios, traditional anti-icing and de-icing technologies have become difficult to promote in practical engineering applications. For example, de-icing with mechanical, thermal, or agents are often limited by energy consumption, environmental protection issues, durability, and operations and maintenance costs. − Therefore, it has practical significance to develop advanced anti-icing materials or coatings with high efficiency, durability, and wide application.…”

In winter, the freezing phenomenon threatens the safety of people both in the work and home environments. At present, electrothermal de-icing technology is widely used, but how to improve the portability and anti-icing/de-icing efficiency of electrothermal de-icing technology has attracted extensive attention. Here, we proposed a simple yet universal flexible electrothermal hydrophobic self-lubricating tape (EHT) with a multilayer structure including an electrothermal layer and hydrophobic self-lubricating layer on a polyimide base. The resulting tape surface exhibits a hydrophobic/electrothermal synergistic effect on anti-icing and de-icing performance. Compared with the electrothermal tape (ET) without a hydrophobic self-lubricating layer, the friction coefficient and ice adhesion strength on the EHT surface were reduced by 29% and 57%, respectively. In addition, the hydrophobic self-lubrication effect of EHT can reduce the adhesion of supercooled water droplets on its surface in an extremely harsh environment to allow more de-icing easily under joule heat, and the different electrothermal power demand in diverse surroundings can be controlled by adjustable voltage. More importantly, the uniform EHT material can be prepared in a large area using a traditional blade-coating process that gives a convenient route to anti-icing in the engineering protection field.

“…In industrial applications, the outdoor equipment was often covered with a layer of ice or frost, , so frost and ice layer melting experiments have also been carried out. The frost formation process is shown in Figure S7, and the melting process of the frost and ice layer is shown in Figure a (Video S1) and Figure b (Video S2), respectively.…”

Photothermal deicing is a noncontact, economically, efficient, and environmentally friendly melting/preventing ice method. Obtaining a cheap, easily fabricated material with high photothermal conversion and deicing efficiency is a challenge. Here, carbon-based photothermal superhydrophobic materials with thermal insulation micropores were prepared by using the salt-template. We demonstrate that the microholes array structure can enhance light absorption and hydrophobicity of the material, and the micropores structure can inhibit the heat transfer from the surface to the subcooled substrate, which synergistically greatly enhances the photothermal conversion. A heat transfer model was established to clarify the influence mechanisms of air cushion on interfacial heat transfer during the photothermal anti-icing and deicing process. The selfcleaning, flexibility, mechanical, and chemical stability tests show that the material has the potential for outdoor application. The prepared materials with high photothermal deicing efficiency provide a new way for the anti-icing and deicing of outdoor equipment.
