Coverable Self‐Cleaning Glass via Abnormal Transport and Jump of Charged Particles

Surface particle pollution is present everywhere, from windows in daily life to transparent curtain walls in tall buildings and photovoltaic panels in deserts. Cleaning these particles takes a lot of labor and costs, highlighting a method for dealing with surface particle pollution that is facile, fast, and sustainable. Here, the abnormal reverse lateral transport behavior of charged particles is reported, the mechanism of abnormal transport and jump behaviors is revealed of charged particles, and the phase diagram of the influence of electric field and particle size on these two behaviors is established. Based on this discovery, a transparent and simple self-cleaning glass driven by the electric field is developed, with a thickness of only 0.62 mm, which can achieve a sustainable surface self-cleaning function when facing organic and inorganic particles. Its cleaning time is ultra-fast, and 97.79 g m^-2 particles can be cleaned in 10 s. The self-cleaning glass can be easily covered to any object surface to achieve self-cleaning and does not affect the function of the object surface, opening a door for no water consumption, facile, fast, and sustainable self-cleaning of various surfaces.
